Hoco J91A-20000

The Hoco brand power bank battery can be attributed to solutions at the junction of the initial and middle price segment, especially considering its capacity of 20,000 mAh (or 74 W * h). On sale, the model is found in white or black, and the body itself is made of fire-resistant ABC plastic 28 mm thick and weighs about 400 grams. Inside, a lithium-polymer battery "hides" with a real (taking into account losses for energy conversion) capacity of 11,800 mAh.

Such a reserve should be enough for two or three charging cycles of modern Android smartphones (for the iPhone - a little more) or one and a half cycles for tablet computers with a 10-inch screen diagonal. The Hoco J91A-20000 portable battery provides a set of 4 ports, namely two USB A, which work exclusively for output, microUSB or USB C, capable of charging only the power bank itself.

You should not count on a fast charging process, because the corresponding technologies (protocols) are not supported, and the peak output power is at the base level by today's standards - 10.5 W. Additional advantages of the model include the possibility of pass-through charging, that is, while charging the battery itself, you can simultaneously replenish energy and connected gadgets.
