Updated: June 9, 2019 / Home » Smartphone and Mobile » Power Pack / Power Bank

Portable Power Bank or also known as mobile powerbank USB charger is a must have gadget for those always on the go. With the rise of tablets and smartphones, without further ado, I’ve compiled a list of branded (and none-branded) powerbank.

Branded vs Non-Branded

Branded portable powerbank are probably 20% more expensive, but the quality is assured. For instant, if it says it comes with 2000mAh, you are assured of getting a 2000mAh capacity battery, whereas a none branded powerbank may display a large 15000mAh capacity due to firmware tweak, or a low grade material that will last only 100 cycles.

You’ve probably seen such images, the photo above shows a fake hard disk with metal rods in it. I remember seeing a fake powerbank with sand bags in it on Facebook. These fake goods are generally sold to tourist in developing countries.

Which is the best USB power bank charger?

Based on the table above, I did go for Sanyo Eneloop Battery Mobile Booster KBC-L2BSP-S, it has 3 times the cycle, meaning to say it can be charged and re-charged for 1800 times. I like Sony Portable Power Supply CP-F2LSA for the large capacity.

The good thing about Sanyo (now under Panasonic) is the low discharge rate, meaning to say you can charge it and keep the battery for 12 months and it still retain 75% of the capacity, whereas other will probably has 0 capacity. Watch the video below on Sanyo’s battery technology

As for Yoobao, 13,000mAh is crazy a lot, provided that they guarantee it comes with such capacity. Honestly, I don’t trust some of the products from China, except for Huawei and Lenovo, which appears to be producing world class goods.

    I haven’t heard of any such incidents where mobile being repaired or damaged because of local power banks ( made in china ) but can’t take risk of smart phones ( 1000 bugs ) better go for branded power banks.
