Where to buy

In this price segment is represented not so much the brand of batteries for smartphones, Powerbank 10000 Rock Slim is one of the best solutions in terms of price/quality.

Again, better to buy on the official website of the manufacturer of Rock on Aliexpress here, as this guarantees the authenticity and quality. Third-party sellers just resell this product, or you can buy only expensive, or it will be altogether fake.

If you specifically do not like this or design it, then I can still recommend powerbank Pineng firms of the same capacity.

Well, for those who want to charge directly from the sun and not from the network 220 or from the car, recommend that such powerbank solar.
