The M9 is connected to the PN 902 power bank and there is no response

In this case, how many hours will it take for your M9 to be fully charged? If it is about the same as the direct charging time, it means that there is a quality problem with the product itself. It is conceivable that this company has no strength to do mobile power supply.

If it is used for 3-4 hours or more than direct charging, it means that there is no quality problem with this power bank itself. However, this mobile power bank does not have an intelligent control chip, which cannot automatically identify the charging equipment model and choose the optimal charging method. It is recommended to choose a well-known brand:

I use LongVIA products, which are very easy to use.

Let's change it, it is recommended to use Romax power bank.

Let's change it, it's a problem with the protection board, and the light won't charge when it's off.

M9 connected to the PN-902 mobile power supply did not respond, but if you connect to *** first, after the blue light is on, after pulling out a replacement It is a problem with the protection board The light is off and it is not charged Change it, it is recommended to use Roma Shi Mobile.

As far as this issue is concerned, I dare not say what caused it. However, this power bank should be dealt with after after-sales.

Inside the power bank is a battery and a motherboard, and the problem is either in the battery or in the motherboard.

1 Brand Value Big brands are relatively more trustworthy, and of course they need to pay more moneyCottages, three no products must be resolutely avoided, although it is cheaper, but buddies can't afford to hurt, the quality is not ***, not to mention, the battery is not good, and there is danger.

2 Capacity size The larger the capacity, the better? I don't know how to say it more accurately. Large capacity means large volume, small volume unexpectedly small capacity, where to go, you need to choose yourself. Personal absolute 5000 or so is the first capacity, taking into account both capacity and volume.

3 Appearance style This doesn't seem to say much, radish greens have their own love.

4 Compatibility Power banks are not a panacea, so you must know which mobile phones are compatible with when you buy them, especially if they match the few electronic products you are using now?

5 After-sales service Whether it is a regular manufacturer and whether it provides perfect after-sales service, this is something that should be paid attention to when buying anything.

Tips about the power bank are basically just a few points, because of the convenience of work, I have used a lot of power banks, in addition to the well-known brand does not need to be recommended, taking into account the quality and performance, **appearance, I think holds the power bank is a good choice.

You can charge and discharge synchronously to see if something is broken, that is, connect the mobile phone while charging the mobile power to see if the mobile phone can be charged. If you can, either there's a problem with the charger. Or there is a problem with the movement of electricity.

The charger may charge the phone directly, and if it can be charged, it means that the power bank is broken. Longweisheng power bank is good. With intelligent control chip.

Pineng's brand is not bad, and now the market sales are also good, it is recommended that you go to the seller's side, and they will help you solve the problem more professionally.

Mine is the same, what the hell is going on? Is there a way to fix it?
