18650 Battery Charger 1-4 Slot Dual 18650 Charging 3.7V Rechargeable Lithium Battery USB Charger I received it well.

Excuse me

The battery picture at the top doesn't go up one spot while charging, but when charging, the red light turns on, and when fully charged, only the green light turns on.

Charging seems good, but it's slow. It's a bit cheaper.

Well received

A AAA 18650 can be charged
It's good

It works well

The product matches the description and was delivered quite quickly from the moment of ordering. Packed well, nothing damaged. The appearance is fine. There is nothing to say yet about the quality of the product

I can, I haven't applied it yet.

I think charging works well

For now it's fine with its work I still have to let it load to try it completely

For the moment well, the contacts of the negative are a little short but it works

Well received. Okay.

It works well

very good
thank u

It's a cheap price, so the quality doesn't look good.
I haven't been charging yet, but I'm a little suspicious.
