  1. D***z

    At first they brought faulty devices, I don't know why it happened, but they were not charged. In the end I wrote off the store and sent me new ones and everything is fine, thank you! The declared volume is kept in full!

  2. П***ч

    Packed smartly, even for a gift. The date of manufacture is printed on the packages in different fonts-2021 year. When unpacking, it showed 3 divisions, but this was clearly not 75%, both cans with a residual charge were not enough to charge one smartphone (4800 mAh). From scratch is charged long enough. After charging one jar is enough for one and a half charging the smartphone.

  3. O***a

    I ordered a power bank because it was written – mini. The size is small, but it itself is thick and heavy – 200 grams. No complaints, since the description included both dimensions and weight. Works.

  4. М***ч

    Welcome, so far it works well, packed well, thanks to the store

  5. I***M

  13. У***а

    Charge and work perfectly!!! Seller recommend!

  14. К***ч

    Works while there are no complaints. There is no fast charging either, because the battery power is probably low…

  15. М***ч

    The capacity of the cans has not yet been measured (I will add a review later), but should be fine, the manufacturer and the store are worthy. Both are charged out of the box on the 3/4. It was packed soundly.

  16. С***в

    Order packed well, delivered quickly. Corresponding to the description, no damage, works.

  17. P***k

    This is a repeat order. I find these basic power banks have no frills and have an excellent capaciy for their size. Recommended, many thanks.

  18. Ж***ч

    Shipped and delivered quickly, packed perfectly, Courier door to door!!! I did not check the quality while I was charging. If possible, I will supplement the review.

  19. T***z

    Good, delivery in time, bought as an extra battery for Oculus Quest 2. it can handle its function, enough for about 3 hours and a half sessions.

  20. З***ч

    Delivery to Moscow a few days, fast. Everything works and charges. But something lower indicator does not shine. And so it seems pretty good

    It's great!

  25. А***ч

    It's great!

  26. А***ч

    Packed well. The power banks themselves are working, the phone charges the battery 3700 2 times. In general, it is excellent as always with a romosse

  27. К***а

    As always great. Would still do protective cases).

  28. A***v

    The banks are great. But one did not work well-you had to press her hard with your finger so that she began to charge. Had to disassemble it and correct the internal components.

  29. И***О

    Great battery! I am not the first such one, I gave about 8, everyone is happy. Came quickly, in 2 days. Charge well, it is very convenient to take on the road because of the size.

  30. И***О

    Great battery! I buy it not for the first time and never let it down. Convenient to use and operate. I recommend it.

  31. S***v

    Chic power banks, the price tag is adequate and the delivery is fast. The package is reliable, nothing crumpled. For several years I have been using the same, but on the 30000, I decided to take a smaller one, for comparison by size-a photo. Recommend!

  32. Д***в

    For 600 rubles power bank super, issued about 9000 mAh capacity. And I took them both for 1150 rubles.

  33. A***v

    In terms of 5 V capacity 6300mA/h. In W/H, taking into account the conversion rate of 37 W/h as described in the description.

  34. П***ч

    Set of 2 light batteries. This is the fourth order in Romos. Impeccable quality. Delivered to Moscow in 3 days.
