Great charger!

29 May 2021

The product came quickly in Russia. the device works. Although I was worried that it would be defective, because I came in a regular carton package .. Even without packing with bubbles .. And the device is heavy enough. At us in the mail are not very careful about the parcels. I'm afraid they might have turned his brain off. Was charged at 78%. In operation has not yet been, T. To a gift to a child. Let's see

Delivery fast and straight home, track is not tracked, store Thank you

22 May 2020

I give my opinion after 1 week of use. 3 positives for this product:-fast delivery from France, order May 09, received May 14 or in 6 days. -The battery is at European standards (CE) with logo present on the battery. -Battery life, I received the battery at 63% and I was able to recharge my Samsung galaxy S7 3000mAh 5 times before the battery is empty. It takes about 2h30 to 3h of time to recharge the battery from 0% to 100%. For now everything is ok, hope it lasts in time.

Good and fast shipping

21 May 2020

To the product no complaints. All as in the description and therefore to the store no complaints. Charged was 75%, the box is broken and opened (torn) a little, but no damage. Very!!! Unhappy with delivery!!!!!!!! Ordered from Russia, went very long (2 months). delivered by courier service sdek. The buyer's protection time came out, I had to open a dispute. During this dispute, the CDEC offered to ride around the city itself and dig their phones in search of their parcel because they it turns out they can not contact me. The dispute did not close, as a result, the Courier, unexpectedly, all the same to me and was able to call, and get there. The goods received 8 days to the end, it turns out, storage even in the SDEC.

21 May 2020

Thank you goods received in 15 days.

20 May 2020

A bank like norm. On % of the category sometimes Strano shows. Then more discharge then normally discharge

20 May 2020

Well, to say, portable charging with high, charges quickly, and itself charges quickly 10/10/10 I will still order. The best store on this trading platform

20 May 2020

Quality is satisfied. It's loaded. Delivery from Russia is very fast, about a week in Tatarstan

20 May 2020

Not bad, like. First I opened a dispute, but then I closed it. Did not charge initially and sat down instantly. But after reading the reviews, they realized that you need to discharge it to zero and everything will be OK! Can't say straight by 100% that 20000 mAh, but charges well.
