    This is a great battery except for one thing, it’s only 6000mAh, not 12000 the listing claims. Using a USB voltmeter I was able to accurately test it’s capacity and it only holds around 6100mAh of power. I tested it a few times and always had the same results +/-5% or so.

    Other than it being half of the rated capacity, I really like the battery in terms of charging. It puts out great power and charges everything I through at it as fast as a 2A wall charger. It also feels sturdy, build quality seems good.

    The solar charging works well for it’s size too. Remember it’s not meant to be the prime way to charge it up, but works well if left on your car dash or similar to keep it topped off and slowly recharge it. I would guess it would take a good 48 hours in direct sun to fully charge it (12 hours in the sun did charge it to 25% in my test – 4 hours over three days during midday sun). This actually is pretty good and on par with other solar battery packs I’ve used.

    I was provided a sample for review. I feel bad giving such a low rating because of this, if the manufacturer changes the listing to accurately reflect the capacity I would be happy to rate it 5 stars. I’ve reached out to the manufacturer to see if I received a bad unit but there seems to be a language barrier. At this point I don’t know if I received a bad unit or if its just way overrated. I will update this review if needed.
