Fine as a battery, not sure about the solar capability...
on 10 March 2016
This is a great idea for a product and as I work at festivals, thought that this would be great for camping. It's a compact and regular size for an equivalent battery source, reasonably light weight in black plastic casing that feels 'ok' but not entirely convinced it would survive countless camping trips. The battery charged my devices, phones etc without any issues; the only issue I had was getting it to recharge via the solar panel.
It does come with a cable to charge manually via USB to any powered device, like all the other batteries available but the USP to this is the solar aspect. I left it in a (reasonably sunny) window for 5 days, it recommended 3, but of the 3 power lights on the reverse it only reached 1 being illuminated. There is an on/off button on the back and the brief instructions do not clarify if this should be on or off or any other specifics to the solar charging. I was a little frustrated and tried different approaches but still couldn't get it above 1 of the 3 lights. I then used the USB cable and it charged quickly to full (3 lights) ready to use again.
I contacted the supplier and they were kind in returning my purchase price with no quibbles but didn't answer my question - how do you charge this properly via solar energy? This was frustrating, maybe it was a product fault specifically to my device only and the other reviewers may have different stories from their batteries, make your decision by reading around - it might just be me!
I did originally receive this at a discounted price for an honest review, I was given a refund, but obviously want to give an honest review. It's fine as a battery for your USB devices but based on my experience, I wouldn't rely on the solar charging facility.
