eBay is awash with these solar mobile power banks, most claiming way more storage capacity than is genuinely inside — this one has just 4,800mAh of LiPos. The unit only charges properly in full sun — in low light it wastes all the energy it receives by burning it up in 4 blue LEDs that seem to stay on continuously. The physical construction is dreadful — everything inside is held together with sticky tape and foam pads. Even the circuitry on the PCB is nothing special. It’s a waste of money — don’t buy it.
