Portable Power Bank or also known as mobile power bank 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 instance, if it says it comes with 2000mAh, you are assured of getting a 2000mAh capacity battery, whereas an non branded power bank 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 power bank with sand bags in it on Facebook. These fake goods are generally sold to tourists in developing countries.
Mobile Power Bank Comparison
| Capacity mAh | Weight | Charging Time | Cycle | |
|---|---|---|---|---|
Sanyo Eneloop Battery Mobile Booster KBC-L2BSP-S | 5000 mAh Lithium-ion | 135g | USB 14 hrs AC 7 hrs | 1800 |
Energizer XPAL Charger Power XP2000A | 2000 mAh Lithium Polymer | 70g | 4 hrs | 500 |
Energizer XPAL Charger Power XP1000K | 1000 mAh Lithium Polymer | 34g | 4 hrs | 500 |
GP Portable Power Bank XPB20 | 4000 mAh Lithium-ion | 130g | 10 hrs | 500 |
GP Portable Power Bank XPB21 | 2000 mAh Lithium-ion | 67g | 5 hrs | 500 |
GP Portable Power Bank XPB28 | 2000 mAh Lithium-ion | 71g | 4.5 hrs | 500 |
Sony Portable Power Supply CP-F1LSA | 3500 mAh Lithium Polymer | 125g | USB 8 hrs AC 4 hrs | 500 |
Sony Portable Power Supply CP-F2LSA | 7000 mAh Lithium Polymer | 198g | USB 15 hrs AC 7.5 hrs | 500 |
Yoobao Magic Box Power Bank YB655 pro | 13,000mAh NiMH | 294g | n/a | n/a |
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 1800 times. I like the Sony Portable Power Supply CP-F2LSA for its 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 retains 75% of the capacity, whereas others will probably have 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 appear to be producing world class goods.
Lithium Polymer vs. Lithium Ion vs. NiMH
| Voltage | Charge discharge efficiency in % | Self-discharge rate in %/month | Mainly Used In | Time durability in years | |
|---|---|---|---|---|---|
Nickel–cadmium | 1.2 | 70%-90% | 20% | Rechargeable Batteries | n/a |
Nickel–metal hydride | 1.2 | 66% | 5 - 30% | Rechargeable Batteries | 2 - 5 |
Lithium-ion | 3.6 | 99% | 5%-10% | Smartphone batteries | 2 - 6 |
Lithium-polymer | 3.7 | 99.8% | 5% | Power Bank / Power Pack | 2 - 3 |
any not made in china powerbank?

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.
