Why is Pinsheng mobile power supply not enough to charge the mobile phone?

Hello, glad to answer for you.

Pinsheng mobile power supply is suitable for more than 95% of smartphones on the market, using high-quality lithium batteries, high conversion rate, and built-in protection system. If you can't fully charge your phone while you're using it, it could be:

1. Affected by the current limit protection of the mobile phone itself, the charging current is small input, so the charging speed is slow, and it is recommended to charge for a longer period of time;

2. When the mobile phone is about to be fully charged, the state of the power supply for trickle, when the receiving value of the mobile phone in the trickle state is lower than the default power-off value of the mobile bank, it may be that the power bank starts the power-off output in advance to protect the mobile phone and prevent overcharging, it is recommended to try whether other models of mobile phones have the same situation;

3. Please check and confirm whether there is any poor contact at the interface, which affects the charging effect;

If you rule out the above problems, it is recommended that you take the product to a nearby store for testing, and the after-sales service needs to meet:

1. Pinsheng**;

2. During the one-year warranty period (more than one year, the after-sales conditions are not met) 4. The product is tested to be a quality problem caused by non-human factors.

Summary. Are you talking about power bank, or power bank, I can't charge my phone.

Are you talking about power bank, or power bank, I can't charge my phone.

If it is the reason for the power bank, the first thing to check is the line.

If there is no problem with the line at all, this is the problem of the power bank.

Reasons for problems such as charging sockets, circuit boards, etc.

It's that the power bank has been placed for a long time. The lights are all on. When you unplug the power supply, the lights don't come on, and there is no power. Rushing doesn't work either.

It means that the power bank is out of power and can't be charged.

Is this already broken?

I dropped it under the table and took it out for half a year just like that, a 406 model.

Plug in the power supply and the lights are on.

It must have been a loss of power.

The loss of power is real, can it be activated?

This is not to say that it can be activated.

It's not a password either, enter a password and it's activated.

The disadvantage is that one of the batteries in it is broken.

1. Check the interface, circuit board, and battery cell of the power bank to see where the fault is. If it is under warranty, please send it for repair. If the warranty period is over, 2, please take it to a knowledgeable and qualified repair shop for repair. If the power bank is very cheap when you buy it, it is not worth repairing, and you can buy a new one to replace the broken one.

3. The most vulnerable power bank is the interface, battery cell, and circuit board. Either one of them will cause it to be unrefillable or unusable. Expensive repair, cheap loss.

4. If the power bank uses 18650 battery cells, and it is still available, you can remove the battery cells and put them into the police strong photoelectric flashlight or anti-wolf electric baton.

5. Some imported or high-quality strong photoshoots use 18650 cells, and are equipped with special chargers for 18650 cells, which can be used for grafting.

Reasons: 1. The electricity stored in the mobile power bank is gone; 2. Whether it is used correctly; 3. Whether the interface between the power supply and the mobile phone is being determined, and whether the charging cable has been broken. If all of this is okay, you should consider whether there is a problem with the power supply itself.
