The solar system doesn't work which is so disappointing . I wish I can send it back and gets refund but I threw the box thinking it must be good since the company is good over all.
First off this product does not charge by sunlight. I left it in the sun for three days and besides having the green light come on indicating it's charging by solar power it in truth did only that, reveal a green light. After half a week it wouldn't even charge one bar worth of energy. using it as a backup battery by charging it through a plug in and outlet works fine and you can get more than a full charge of an i-phone through it. But as a solar charging battery that's a lie. I thought it might have been my unit so I even exchanged it for another brand new one and left it in the sun for 5 days and still nothing! Don't buy this.
I wish I would have read the reviews. I've tried for over a week to charge by sunlight and nothing. For the same price you can get a better charger that you have to plug into a wall anyway. Don't waste your time trying to charge this by the sun.....life's too short!
I did some tests and the solar panels only charge at about 30-40 mah at 4.9 V when the green light is fully on. expect less due to the green light indicator. this is a 0.2 watt input. normal usb charges are 2.5 watts-10 watts depending on the charger, which is why the bank takes forever to charge in the sun. its a great power bank. just expect to charge via usb for an hour.. or via 100% direct sun at 25 hours and 100% efficancy. Direct sun is like at high noon with the solar panel perpendicular to suns rays. Efficancy drops the more filled the battery is so current will drop.. expect to spend at least 40 hours pointing this thing at the sun.
The solar charge function didn't work once. Very disappointed with this product.
I should have read the reviews. Its fine as a simple battery charger, if you charge it from a USB source. The solar does not work. I even exchanged it for another and had the exact same issue. Don't waste your time!
Been charging it in the hot August sun for a few days and it barely charges at all. Not even enough to turn the light on. Maybe I got a dud. If I plug it in to charge it it charges up quickly. But not even enough juice to charge my iPhone 6 twice. Don't buy this product!
this works as a regular battery pack but the solar charger doesn't work. left it in the sun all day and there was no increase in power supply. it's also really light in material so the quality isnt' that great.
Originally when I was in the market for a power bank I was just going to buy something that charges from USB. The solar panel was a big component of buying this charger.
The solar panel doesn't charge at all,
If I charge my phone from the fully charged battery it brings the power level down to 1 bar. So I may be able to get 1.5 charges on one device from it.
I expected a lot more, I feel the way it's marketed is misleading.
Great device when charging from electrical source. It can hold enough charge to fully charge your phone or other device two or three times. However, it doesn't charge so well by the sun. I'm not sure how long it would actually take to fully charge through solar, but my guess is probably a week.
Overall I would say it's an ok product and good to have around when your battery is low and you're not near a wall plug.
I left it in the sun for DAYS and it did not recharge. I will be returning it! Waste of money!!!
Product was charged once with the sunlight, able to charge my cell phone one time the the product was never able to hold a charge again. waste of money, I lost the packaging to this product but i will try to return it anyway.
Charged it once through the cord and it lost all of the charge within a few days. Left it in direct sunlight for a full day and it did not charge at all. Tried charging with the cord again and it stopped at 2 bars. Will be returning this product.
