This battery comes partially charged. I fully charged and discharged. I then made two charge / discharge cycles on the same smartphone to have the most reliable results possible.
I got a 7050mAh average rate of return of 88%, which is excellent, and making the measurements several times on different devices. This is what you would expect from a high-end external battery but we must bear in mind, when you bought it, that it provides is 5150mAh and 5200mAh between to see if it should your needs.
These very good results are partly related to the fact that this battery is built with Li-polymer cells, more expensive but more efficient than 18500 Li-ion cells typically used for this type of object.
This battery was designed to be small: to give an order of magnitude, same width as a smartphone 5 "and be light.
This led the manufacturer to make certain choices: no torch function, there is only one USB output 5V / 2.1A.
Charging time I found is about 12 (no fast charging).
From quon receives, we feel that the manufacturer, this is one of his trademarks, has paid special attention to the quality of construction and design.
It is delivered in a sturdy box, which itself contains a drawer case (green in my case). Inside, there is of course the battery, a flat charging cable of sufficient length and a case which, although not concrete, really protect the battery unlike the bags sometimes supplied by other manufacturers.
The quick guide in several languages including French. There is more than enough and scarce enough to be noticed, the French translation is good.
There is no dadaptateur sector. This is what practice 90% of manufacturers and easily sexplique: they are the same products that are sent all over the world and it would then send adapters to all standards which would have a stroke. Having home adapters, I prefer not to pay quen pay a plus an American English etc.
Once seen lon battery, one feels that the construction and quality. This is the solid (including the button flawed on some other batteries), pleasant to handle.
The look (jai white version) is nice and discreet. The battery fits easily into my small bag mans beside my smartphone.
If I had to find a fault common to many batteries, it would Indicator load: When it quun still led on, we do not know sil 25% remains in the battery or practically anything.
Best of all, the builder, AMZDEAL, used as much as possible recyclable materials.
I have been seduced by this product that delivers the level of lampérage provides, which is well built. Its range is not huge but enough for a battery that is truly mobile. There are good batteries with more of autonomy but their weight makes quon can hardly carry them constantly.
A battery that i lent to friends who bought and then lont whose quality makes you want to know other dAMZDEAL products.
If the characteristics of the battery fit your needs, I can only recommend it warmly.
