Delivery is instant-I ordered it on May 9, and on May 12 I already had the power bank. I watched a video review about him on YouTube, they claim that he has a capacity of no more than 2000 hours! I decided to jam it myself. I immediately discharged it to zero, recharging the discharged phone, and then put it on charge overnight. The tester showed that the declared capacity of 3350 mAh is true! Judging by the tester, the power bank was charged for 5 hours and its capacity was 3397 mAh!

First of all, I was a little nervous because there was only an option that could not be delivered, but it arrived much faster than the expected delivery date. Yo ~! Seller thanks ~! And the finish of the thing is actually better than the picture. Uh, man. The design is perfect ~ Good/I'll sleep! It's strong!!!

Matches the description, the smallest I could find (not counting the options with built-in wires, which I don't really like). IPhone 13 charges on the 70%. Of the minuses-not very fast charging, maximum 5 V, 1A and in and out.

I was looking for one specifically, came with a delay of several days. We will check the work in the future, I think it will justify itself, the price is pleasant.

The parcel arrived in Tyumen 27 days from the date of order, the track number was tracked normally. As for the product itself, this is not the first time I order for my family, everything is fine, compact, convenient, except for rolling on inclined surfaces. So the phone will recharge while running errands.

Neat, no flaws. Black color. When charging, the indicator lights intermittently blue. When charging gadgets, it shines constantly. Full battery charging lasts a couple of hours.

A simple filling on a microshoe ip5305, a direct-to-datashite circuit, one 18650 element. Indication-only one LED, a few minutes before the discharge starts to flash, it is impossible to determine how much charge in the battery. Charges from scratch in 6 hours, of course there is no fast charging. Too low-current devices (such as Arduin) will not work, turns off the load. You can make a trick, you just have to collective farm. Justifies his goals, the price is clearly overpriced. An analog from a case with the same board and batteries can be bought here several times cheaper. In general, he took from behind the cultural building and small size-into his pocket. Can be recommended.

The power bank is small, light, while performing its functions normally. Of course, the modern smartphone will not be able to fully charge, but it allows you to significantly recharge. In general-a good road option.
