Video reviews At first glance, the battery from Asus is very similar to the Xiaomi Mi Power Bank 10000. Both in appearance and specifications. similarityIndeed, Asus ZenPower has a similar aluminium case, which does not differ in width and height from a regular credit card, and approximately the same effective capacity (about 6600 mAh). The differences lie in the larger output current (2.4 A instead of 2.1 A), as well as in the location of the remaining charge indicator and the USB port, which, unfortunately, is only one. 2.4 A of the output current allows you to gain a little time in charging gadgets — the Asus ZenFone 2 battery with a capacity of 3000 mAh will be fully charged in about 2.5 hours. CaseThe aluminium case of the battery is a definite plus. But if you put your phone close to it, there is a risk of scratching it. Therefore, Asus' savvy engineers added a special case called the Asus ZenPower Bumper to the package. It will not only protect the device and gadgets in contact with it, but also paint the external battery in a bright colour (black, blue, orange or light green). ProtectionIn the event of overheating, an increase in the voltage level above the nominal value or a short circuit in the battery, the built-in protection is activated, which will keep the device in working order. OnlineThe battery does not take up much space and is useful to anyone who wants to always be online, and the built-in battery in your favorite gadget is not enough for a whole day of use. | Filters Models P/N: 90AC00P0-BBT001 90AC00P0-BBT002 90AC00P0-BBT003 More ↓ 90AC00P0-BBT004 90AC00P0-BBT005 90AC00P0-BBT026 90AC00P0-BBT027 90AC00P0-BBT028 90AC00P0-BBT029 90AC00P0-BBT030 90AC00P0-BBT076 90AC00P0-BBT077 90AC00P0-BBT078 90AC00P0-BBT079 90AC00P0-BBT080 ABTU005 |
1) преобразователе напряжения от клемм аккумулятора до выходных 5В;
2) схеме зарядки в гаджете;
3) самом аккумуляторе гаджета в процессе зарядки - от отдаёт энергии меньше, чем получает.
Поэтому общий КПД 60-70% это норма жизни.
В мооём случае после небольшого разгона (два полных цикла) Asus ZenPower зарядил смартфон на 3300 мАч два раза, и ещё чуть-чуть ёмкости осталось. Я считаю - превосходный результат.
Кроме соответствия номинальной ёмкости, хочу отметить ещё признаки правильного павербанка:
1) при подключении входа на выход сам себя не заряжает (есть защита);
2) в процессе собственной зарядки позволяет заряжать гаджет (в этом случае большая часть энергии уходит в нагрузку, а аккумам повербанка достаётся по остаточному принципу).
