Packing is a box the size of the video cassette, vnturi bank and usb cord. In general, presentable. The capacity for the charge is 3250, the discharge is 2100. That is, the average smartphone charges from scratch almost completely. Plastic housing quality. The led is moderately bright, not annoying in the dark. As a result, of course, more expensive than a separate case and a good bank, but a good case separately buy unreal. So i recommend. Delivery days 10 (i.e. Do not shibko warily for express delivery).

Excellent banks! Ordered two at once and did not lose! Needed very compact with fast charging! Delivery in moscow for a day (at night ordered and already in the middle of the day the courier delivered home) perhaps it is necessary to buy a couple more while the price of norms!

Small and light. I have 10 and 20 mahs, but to carry them every day, given that they are needed once a week maximum, somehow not comilfo. This one took as an emergency option in a backpack, if on the road suddenly smart sits down, a little recharge is enough, and if i know that i will not see the outlet for a long time, i take large cans. I plan to order another one in a bike first aid kit, that would not shift each time.

Delivery is very fast. Works: charges the phone and charges itself. Small and light. Minus-there is no charge indicator. I took it as a gift, i think i will like it.

Excellent bank. The body is qualitatively made. No load produces 5.1 v, with a load of 4.99 v at 1.14a-1.2a. The container has not yet measured. The feeder inside is not bad. Inside i understand it costs 18650 battery. And i hope it will be possible to change over time

Came quickly with delivery home! Well done guys! Came discharged, recharging the battery from an hour, charged his iphone for 20%!! After another charge of the battery that lasted for hours four charged completely its iphone. In general, this external battery costs its money at least, very compact and cute! I recommend!

Everything is wonderful, a day after 3 after the order brought the courier, with which we previously discussed a convenient delivery time. To power bank itself no complaints-works fine.

First bought 1, fully charges the iphone with 0, but it is discharged itself. I ordered another 5 for gifts-very convenient as a reserve. You can always carry with you.

Works, enough for almost one charge of the smartphone with a 3100 mah battery

Externally, it seems not bad, but i thought it would be even better. I have not tried to charge this battery yet, how much real capacity i do not know, and how to know it, too, i do not know. I think as the nw will come down.
