Portable Mobile USB Power Bank Charger Pack Box Battery Module Case for 1x18650 DIY Power Bank
A part of the review has been auto-translated.
This is a very cheap Power Bank with an acceptable price. The product does not contain the battery, but the price of the item compensates for this deficit ... It has a good price-value rate!
Bom ,produto apesar de simples ,pelo preço é bem construído.
Good powerbank already tested, with built-in overload protection. The maximum output current is 1A, that's a bit low, but for the price, I won't complain.
Not bad for the price. They work as well as a more expensive sealed unit but you get to hunt around for the cheapest battery you can find and replace it when it is at end of life. (I get them from old laptop packs where there is usually one bad one failing the pack and the rest are good and otherwise wasted.)
works fine....Small opaque window , which allows an led power indicator to be seen doesn`t attach easily . probably requires gluing to plastic lid rather than the press fit.... no usb cable or instructions are included. very pleased with purchase....will be using to power outdoor 5v led lighting .
Reasonably well made powerbank considering the price. If you have a lot of old unprotected 18650 cells lying around it's a a good solution for slow charging devices or as an emergency backup.
A power bank works very well. Consumers can be operated with low current consumption (40 mA). The 2nd power bank switches off at consumers < 50 mA.
This is a good PowerBank with unbeatable price! It has no battery and doesn't support all devices, but with this price it is acceptable...
Yonk yoke poke! This product is amazing! Perfect for Williamellor!
Good little battery charger / power bank, works well. Can also be used for diy electronic projects, where battery power supply is needed.
