Just recently a Chinese copy of the 2nd generation iPod Shuffle came to me from China. You can see an overview of it -
The player is very, very cheap, purchased for only $1.73. The sound quality is satisfactory (no noise), does not slow down. In general, I'm happy with everything.
But there is This player has one flaw - there is no battery charge indicator . Therefore, I decided to write this article to tell you how long and how to charge the Chinese iPod Shuffle.
1. Take a cord with a Mini USB connector.
Mini USB looks exactly like this and nothing else:
2. We insert Mini USB into the special connector of the player:
3. We insert the other end of the cord into a regular USB connector on a computer/laptop:
4. The activity indicator should light up. This indicates that the player is charging:
While the player is charging, it operates in card reader mode - you can download music files, etc. to the device.
Since there is no protection circuit on the battery itself, the player should be charged for no more than 1 hour (maximum 2 hours) when completely discharged.
If you often keep the player in charging mode beyond the allotted time (more than 1-2 hours), the device will quickly become unusable!
Based on my personal experience, I will say that a fully charged battery allows the player to work for about three hours.
It happens that you come across defective players that only hold a charge for 20-30 minutes. But this is an exception to the rule and is rarely observed.
Music players require constant power supply, otherwise they will simply stop working. But if you just bought it, and have never held anything like it in your hands before, it will be useful for you to know what to do to make it sound again.
First, let's figure out what types of players there are and what you need to charge them. Today there are only two types of them: those that are powered by ordinary AA batteries, and those that have a built-in battery. To charge, you need a USB cable, a battery charger and a USB adapter for a power outlet. All this may be included with the player, or you will have to buy it separately. Now a few rules before you start charging the player. For devices that run on finger (pinky) batteries, we recommend replacing them with special rechargeable batteries, as they hold a charge much longer. In addition, these “batteries” can be recharged, unlike conventional ones, for which recharging threatens to lose useful properties or even leak, which promises damage to the player. If you have a player with a non-removable battery, then it holds a charge longer than the first one, but if the power source breaks down, you will have to have it repaired at a service center.
Finally, about the advantages and disadvantages of different charging methods. The first method is universal and completely safe for your player, although the battery will charge slowly. The second is, on the contrary, risky due to voltage fluctuations in the network, although it does not require a PC. And the third is good because you can charge the batteries faster than the previous ones, but their service life will be reduced.

When purchasing a player in stores, sellers advise you to immediately buy a charger for the player (unless, of course, it is not included in the package). This is due to the fact that the player is not fully charged via USB. Is this true or just a scam for money?
P.S. I noticed with my player (Cowon U5) that it charges via USB, sometimes quickly, sometimes for quite a long time.
7.02.2009 - 11:58:15
I bought it for myself, but for a completely different reason.
At work there is no way to charge from the computer, so I charge from the network.
At home I plug it into the computer and I don’t notice any difference in the operating time from different charging sources.
8.02.2009 - 02:04:45
I bought a wall charger for my kovon7. The fact is that when you connect to USB, the display shows that it is connected to USB and that’s it. And if it’s against the wall, then an animated picture is shown, saying it’s charging. When charging is finished, the battery in the picture is all plump! And what actually happens there in both cases - the devil only knows. There are two types of USB in terms of power: some are power, you can connect 2.5 HD without additional power, others are low-power. I don’t think that in the case of charging the player, power plays a role - the load is too small.
8.02.2009 - 05:57:27
I don’t know about players, but my phone cannot be recharged via USB (and neither does my husband’s). Moreover, the icon that recharging is in progress is shown, but in reality it is not recharging. Or it recharges, but just a little...
11.02.2009 - 10:25:52
In any case, it charges faster from a charger than from a computer. For my Cowon U3, I bought a charger from a Motorola phone with a USB connector. Everything fits perfectly and charges perfectly.
15.02.2009 - 07:37:49
I don’t want to stick out, but my IPOD manages to charge in the car while you’re driving somewhere, and very quickly; it lasts for a very long time, I think 25-30 hours, if fully charged. At home from the computer, while you’re adding something
21.04.2009 - 18:28:06
I bought it for 150 rubles. and did not waste my thoughts on this serious question of the universe
22.04.2009 - 02:18:15
After connecting Cowon 7 to the computer's USB, you need to perform a “safe removal of device” via the tray icon. Then an animated cup will appear on the player screen.

Fast charging is only good if you are sure that the charger is “smart”, i.e. controls the parameters of the charging battery and limits the charging current or voltage. Otherwise, regular fast charging may lead to premature battery degradation.

I have a Creative ZEN four gig.
First I charged it from the laptop's USB port. But I encountered a minor problem - the infection falls off, and Windows croaks every 10-15 seconds - either the device is found or removed. I decided to use the charger from the Lbook™ eReader V3ext kit. I did not record the charging time in both cases, because... I connected the player overnight.
The results are very different. When charging from USB, the battery lasts much longer. And after charging from the power supply, some inappropriate behavior of the player was also noticed: the discharge indicator is halfway, and after about an hour and a half it drops to zero, the player turns off...
Now I charge again from USB. In Windows I set the sound mode to "Silent". Let him croak to himself.
ps. krokik
According to the USB 2.0 specification, all ports must provide 5 volts 0.5 amperes per port. there are no power-non-power. if you need to power an external hard drive, then they provide a special cable for it, which can be plugged into 2 USB ports, thereby providing 1 ampere.
22.04.2009 - 06:56:10
Thank you!!! Well, it’s just my case - absolutely the same thing happens! I will know that I need to charge from USB
22.04.2009 - 07:02:16
They should, they should, but in practice... My external HDD Transcend works great on some computers without this additional cable, but on some (in particular, on the home computer), even if you plug it into any connector, it won’t work on one cable. I don't use extension cords. The computer's power supply is good, with a large power reserve.
22.04.2009 - 13:52:24
Malvado
Well, yes, it depends on the manufacturer of the hardware. specification is specification, but how diligently our Chinese brothers follow it...
I have an ACER laptop at home, and at work a computer based on a motherboard from GIGABYTE. So even the player, this same Creative, feels great on a GIGABYTE (although the power supply in the computer is a cheap PowerMaster), and if you plug it into your home laptop, then until the battery is charged, it’s impossible to put anything into this balalaika - as I wrote, periodically After 10-15 seconds it falls off.
I don’t have a cable with two USB connectors. I couldn't find it in stores...
22.04.2009 - 14:51:37
I’ve only been using the Sony NWZ-E436F for a month and I was also afraid that I wouldn’t be able to do without a charger. It costs almost half the price of the player. But it’s good that I wasn’t in a hurry to buy. I don't feel the need for it at all. Charges quickly using a USB cable. The battery lasts 45 hours and has to be recharged every 2-3 days.

I didn't understand...
22.04.2009 - 18:01:21
The battery is designed for 45 hours of continuous operation of the player. I don't wait for the player to be completely discharged and recharge it about once every three days. I listen to books every day.
22.04.2009 - 19:50:50
According to a familiar battery specialist, both the voltage and current supplied by the source are important for full charging. According to him, charging a lithium battery with a current less than the nominal one leads to systematic “undercharging” and a sharp decrease in capacity (for nickel batteries the opposite is true...)
Probably, if “wall” charging provides a current of 500 mA at a voltage of at least 5 V, its use is highly desirable. Another thing is that you can’t check this parameter when purchasing! You can only rely on an inscription like 5-9 V 600 mA if it is a brand.
Using a computer is also absolutely normal, the normal charging mode provided by the player’s developers. The main thing is that your computer's USB connectors meet the specifications, but how can you check this?
23.04.2009 - 00:57:07
Kovon, according to the passport 50 hours. I listen to it every day for about two hours.
I charge when the charge indicator is halfway, maybe once every two weeks...
23.04.2009 - 06:14:01

Maybe I should recharge less often? I listen from 2 to 5 hours and am afraid that I will find myself without a player at the most inopportune moment. And without books I feel empty, especially in the car.
23.04.2009 - 14:10:11
I would advise keeping an eye on the charge indicator. He can experiment - how long will it last if he plays without recharging until the end, when, for example, only one third of the battery is shown.
23.04.2009 - 14:39:42
Fine. I'll play around and share the result
24.04.2009 - 12:11:08
Is it true. I also have a Kovon U5, I bought a “socket-USB” adapter and noticed that the player began to discharge more tightly. But it still doesn’t reach the promised 24 hours. Maybe I should have started charging from the outlet right away?

Did you measure the consumption in the city or on the freeway?
The promised 24 hours are probably obtained at the stand, when it drones monotonously to itself without turning on/off, increasing/lowering the volume, video, text, etc.
29.04.2009 - 18:13:04
And I accidentally plugged a cell phone charger (Philips) into my Kovon. I only noticed when an hour had already passed. I was so scared! And nothing! Everything is fine. Recharged. But now I don’t want to take risks and I’m careful not to mix it up.
30.04.2009 - 10:15:41
All problems are caused by excess capacity! My old Philips 512M doesn’t have such problems. A file charge lasts for 1-2 days. Then you still need to plug it into your USB to charge new files. If you don’t pull it out right away, after half an hour it’s all charged again. I mean electricity in addition to the files.
30.04.2009 - 16:18:12
Moreover, even players of the same brand can behave differently. My wife and I have the same players, mine is older. Different computers behave differently. The older one is omnivorous. A younger person on one of his home computers refuses to manipulate files.
The device is quite cheap.
Charging from the wall is indeed noticeably better quality. Having such a device is even practical when you are going somewhere for a long time.
30.04.2009 - 17:13:31
I finally got to the “wall” charger from Lbook. It says on it that it outputs 5 volts and 1 ampere. I mean, it can give 1 ampere. which is 2 times larger than the standard USB port of the computer. If you believe the Device Manager, then when you connect the player, this very port outputs the required 500 milliamps. but the instability of the connection leads to all sorts of different thoughts about these amperes.
However, from the computer my Creatiff charges noticeably more densely.
1.05.2009 - 04:38:37
It’s impossible to generalize here.
When it comes to charging players, I use common sense. Still, a computer is a more serious device and there is more trust in it than in a cheap plastic box, stamped somewhere and by whom. Therefore, at home I charge only from the computer. And when traveling - well, there’s nowhere to go - from the charger.
1.05.2009 - 05:04:38
5V in a computer comes with a power supply, in cheap models the schematic design and element base do not differ from “no one knows where and no one knows by whom”, and is often produced by them (sometimes they change the “brand” stickers to order)
1.05.2009 - 14:09:41
The computer (its components) is usually stamped by an even more unknown person and where!
The attitude towards USB as a power source is not serious. There are power USBs, capable of holding 5 volts with a relatively powerful consumer (external hard drive or scanner without power) and low-power ones - suitable for flash drives. Connecting powerful consumers to a low-power port reduces the voltage and can completely damage it.
A “plastic box,” on the other hand, is a very simple device, the only purpose of which is to maintain a certain voltage at the output, regardless of the load (a discharged battery is many times more powerful as a consumer than a charged one). And some are even more advanced - they adjust the voltage depending on the charge of the battery.
So common sense still speaks in favor of the charger!
1.05.2009 - 19:10:07
On my computer I know where everything is stamped because I assembled it myself.

Isn’t this a superstition from historical batteries “with memory”?
16.07.2009 - 17:40:41
I bought SONY batteries for the camera from a “battery-rechargeable-charger” wholesale company. Nickel-Metal Hydride (Ni-MH). They said you need to do several charge-discharge cycles. And then just recharge as needed. And forget about “memory”.
PS: today I was left without a book again, because I was working away, and there was nowhere to recharge the built-in battery... I want AAA back
ZZY: yes, by the way, I tried to assemble the charger. I bought a plastic block on the market, which consists of three seats for AA batteries, and glued a USB connector to this block. I thought, I’ll plug in three batteries and let them charge the player on the train. Did not work out. The player doesn't even see the electricity connection. I'm afraid to connect four batteries. because if after charging they can produce more than 1.35 volts... I already burned the iRiver T30 with an external power supply...
Now, if you could assemble a circuit that gave 5 volts at the output, if you connected 4-5 AA batteries to the input. lack of knowledge. and people who know me don’t want to bother with such garbage.
18.07.2009 - 16:23:59
Well, this is what I did myself:
http://goods.marketgid.com/goods/758/2722356/
I was just afraid to install 4 batteries. I took a box of 3 pieces.
although there is also something ambiguous here: “A universal charger with which you can charge AA-size batteries via a USB connection to a PC.”
you need to do the opposite - use AA to charge the player.

I listen to music through my mobile phone, everything suits me, I don’t use an MP3, and the phone is charged directly from the computer when I download music

I agree that in theory there is little reason not to trust chargers. But practically I have more confidence in my computer. I just know that its power supply has been ensuring glitch-free operation of all devices around the clock for two years now. The entire computer is protected by not the cheapest UPS. The socket for the computer is, as expected, three-wire. Therefore, the likelihood of possible tricks on the part of the electrical network and elements of the power supply system, I think, is still less than in the case of the charger.
I apologize for the resuscitation.
The charger may have a higher current rating, in any case, with USB the voltage and current are very low due to its multi-functionality, but on the charger it is higher, so the battery charges faster when charging. Lithium batteries must have a built-in controller whose task is to control the charging process. If the battery is of high quality, then nothing depends on charging (in the sense of damaging the battery). In practice, charging on a PC is inconvenient, especially if the battery is very capacious, USB is often needed, so I charge from the charger. Problems can only arise if the charger produces a very high current, for example 1000 mA, this is too much for the player’s battery.
22.10.2009 - 10:33:52
If I'm not mistaken, then - due to the specification.
If I’m not mistaken, the port limits the consumer to 100 milliamps. (By the way, the current consumed by the power is shown in the equipment properties)
The battery electronics are most likely poorly protected from a number of interferences that can damage them. for example, a surge of several kilovolts, which is filtered out by larger (structural) devices due to the greater number of parts used in them
but USB charging from the network is still a very tempting object
The current consumption is determined by the consumer-player, and the port or charger can only limit it. increased port or charger current cannot be harmful to the player. it just won't all be used
By the way, 1000 mA does not seem to be such a large current for 5v power supply. You may have even more currents, in my opinion, with capacious and fast-charging batteries. so you should keep your contacts clean

Well, yes, by specification, of course. Error. The right word didn’t pop up in my mind, it’s time to cleanse my brain of junk. No, I certainly won’t listen to audiobooks at higher speeds.
Voltage surges! Don't be so scared. What about multi-stage automatic transmissions? Although it is different for everyone, such disgrace is still rare.
Of course, the current strength is determined by the consumer, but, apparently, the battery electronics are responsible for this infinitely. For a battery from a screwdriver, such a current may be small, but for a player it can burn out. I don’t know for sure, I won’t lie, but personal experience tells me (I once connected such an adapter to a radio receiver) that in this case, the higher the current, the worse it is and it’s not worth experimenting with. The adapter is matched to the battery, but on the player it is low-power, otherwise all adapters would be the same, they would only change the output voltage.
22.10.2009 - 12:12:03
but in practice I didn’t hear this happen often
The charger's parameter is its voltage.
which should naturally correspond to the consumer player. The player can burn out only if you charge it with a charger whose voltage is higher than required.
The charger itself can also burn out if its MAXIMUM current is less than the current consumption of the player. (I don’t know how USB ports survive here)
Apart from the output voltage, connector design (and polarity!) and maximum power, the chargers are absolutely no different from each other. It is likely that there will be a trend towards all devices switching to USB charging. and this connector itself will become the standard for low-voltage 5v pins
There are also power supplies that output alternating voltage; power supplies with a constant output voltage (OUTPUT) are marked with a straight line icon and a dotted line under it. and with variable voltage - a wavy line. the input (INPUT) on all power supplies is naturally marked with a wavy line
If you are using a power supply that came from nowhere, then keep in mind that it may be faulty and output something incomprehensibly destructive to your player. so it’s worth checking the output parameters with the device before poking. I also assume that there may be charges whose parameters the manufacturer guarantees ONLY on the native device. that is, tied to the parameters of the consumer input circuits. but in practice I have not seen this, it seems
I'm not good at electrics. I need to restore information and knowledge.
I chalked it to protect against power surges in the home. For example, I have a common machine installed in my apartment, then three are divided into sections per apartment, and so-called filters. Perhaps my ideas are wrong, but how is the PC more protected in this case? Although you are right that the charger must be of high quality.
The charger's parameters are voltage and current. Perhaps my misconceptions are caused by the fact that information pops up in my mind that the severity of electric shock is determined precisely by the strength of the current, and not by the voltage.
And the value of 1.5 A on USB is of course an error, I looked at a dozen and a half chargers and adapters at home and did not find a single one with such parameters.
