I bought this Baiter / SUPER-BAB 5200mAh Power Bank from Amazon UK on a lightning deal for £11.99. Current price is £12.99. It does not meet the claimed specification of delivering 2.4 Amps, and delivered capacity was disappointing at only 76%. I do not recommend this power bank.
If you really must, you can buy this from Amazon UK - This link contains an amazon referral link which helps me to buy more power banks to test.
In the box
Nicely packaged, good box with the powerbank and cable held in a foam tray. Small user manual included. The power bank has a fake CE mark (China Export rather than Conformité Européenne). Very shiny case is a bit of a fingerprint magnet.
- Dimensions: 105 x 42 x 22 mm
- Weight: 124 g
- Capacity: 5200 mAh / 19.24 Wh
- Micro USB cable length: 29 cm
- Input: 1 micro-USB
- Output: 1 USB A - 5V up to 2.4A claimed.
Poor. Immediate voltage drop to just over 4V at 2.1A which then slowly climbs back to 5V. It’s happier if the current is ramped up gently, but this is not a good performance.
Standard cheap power bank cable that’s 29cm long. Virtually no strain relief. 7% voltage drop at 2.1A which is underwhelming for a 30cm cable, but not the worst I’ve seen. Basically as expected for a cheap included cable.
After approximately 3 minutes at 2.4A the power bank turned itself off having delivered just 919 mWh, or 5% of the expected capacity. A second test at 2.4A resulted in 933 mWh. I re-ran the test at 1.5A discharge which is the standard for a USB dedicated charging port, and the power bank delivered 14656 mWh or 76% of the claimed capacity, which is poor compared to the normal 80-90%.
It did cut the power off cleanly at the end.
The 4 LEDs do seem to approximately represent 25, 50, 75 and 100% capacity.
Standby Power Loss
Approximately half full after sitting on my shelf for a few weeks. I’m not sure how full it was when it arrived.
