Bests & Worsts Reviews from Amazon

Bought this for a trip, had it charged up the old school way, solar power and let it slow charge. Took it on my trek, didn't need it until day 2 and charged 2 devices with it. On day 3 had a little charge left in the bank, put it out in the sun in the morning in full sun and let it charge for over 10 hours. That evening went to charge one of my devices and it had no power in the bank. The lights just kept cycling on the bank, put it out again the next day, left it out over 10 hours in full sun, tried to use it that night and nothing, nada, zip. Tried to return it and cannot, don't think you can contact the seller either, you'll get frustrated and find this is a futile attempt. Doubtful they will contact you if you leave a poor review. If I could give a negative 5 stars I would. I would highly recommend purchasing another solar power pack, bought this as the reviews were high and the capacity was a tad bigger than what I needed. Waste of money and I have only had it 2 months and used once and now I am stuck with a solar charger/battery pack that cratered. Ended up ordering another solar power charger and hopefully this one will work in the field. Going to use this as a doorstop at the house now or maybe a weight when I go fishing. Waste of money and my time and lots of frustration. My opinion of this is low, low and low. You can find a better one, do yourself a favor and shop around.
