Mobile phone makers launch own-brand powerbanks.
Bangalore, May 20 2015: We at IndiaTechOnline, recently surveyed recently launched third-party power banks ( Pocket Power ) and suggested how best to use them (Stepney Power!). Our technology trend report has been overtaken by an interesting development: the launch of own-brand power banks by mobile phone makers.
These powerbanks work with all makes of phones - but their power rating is carefully tailored to provide 2-3 full charges for the maker's own flagship phones. Huawei has recently launched the AP007 Honor, a 13000 mAh power bank which costs Rs 1399 and is obviously aimed at users of the Honor phone range.
The Xiaomi Mi Power Bank packs 10400mAh for just Rs. 999 and is capable of 2.5 recharges for the Mi 3 and 4.5 full charges for the iPhone 5s.
We got to try out the latest launch in this category: ASUS ZenPower which offers 10050 mAh in a compact package that the size of a credit card -- but the comparison is misleading because it is about 2 cms thick and weighs 215 gms. It can give 2.4 charges to the recently launched ASUS Zenfone2, which runs on a 3000 mAh lithium ion battery.
It comes in a thick aluminium casing which can take a bit of rough use and the makers claim it has PowerSafe Technology which monitors temperature, controls both input and output voltages, and guards against short circuits. Since we didn't test either power bank or phone to destruction, we can only take their word for it.
The charging current is 2.4 A which considerably reduces the charge time when compared with most of the smaller capacity 1A charges. An at this current and mAh rating the ZenPower can also charge most tablets. It costs Rs 1499.
