Solar Charger, YELOMIN 20000mAh Portable Solar Power Bank for Cell Phones, Dual USB 5V Outputs/LED Flashlights and Compass, Waterproof External Backup Battery Pack for Tablets and Electronic Devices

So, the unit works well at charging my iThings and such. There are a value added few gadgets like a compass and the light too. I'm wondering if the compass is actually accurate as it's embedded in a metal housing with a big battery. I'm sure there's no electrical field disturbances to fiddle with the compass. LoL. The solar panels are curious. I've had it in a sunny window (hours a day of sunlight) for several days and it hasn't been able to top off the storage capacity with one bar left to go. So I'm calling bullsh*t on the solar feature as being functional. :-) Nice storage battery otherwise. Durable case.

Wow this power bank is unbelievable cause when its battery is over you can just a put it under the sun and it gets charge from the sun and honestly when i was buying I didn’t think it would work bit now wow it works

Very satisfied! It's charging my phone and running a desk fan at the same time. Fast charges my phone too!!! Very happy with this purchase. Read instructions though. Need to charge power bank at 10 hours before relying on solar charge. Just sayin.

This portable charger completely surpassed my expectations. The charger is very sturdy and feels like it can withstand the natural elements of the outdoors. There is a nice grip to it as well. It comes with a clip that I’ve been putting it on my bag and letting it charge as I’m on the move. The amount of charge this product can produce is plenty to get me through the day. I was surprised to how easily it picked up charge from sunlight and how bright the LED emergency light is. Solid product and would recommend to anyone who enjoys the outdoors.

Before I got this I never remembered to charge my power brick. That hasn't been a problem since, just sit it in your window or on your dash and don't worry about it. Also the 20000mah capacity is crazy, I could charge my phone 5 times over and it'll last all day, if you have an old phone you could charge it 10 times that's almost a week that you could make your phone last with no power source and then you add solar charging, now it's infinite.

This is a handy little invention. It has a built in compass and a flashlight with a flashing pulse light and a quick flashing pulse light. It appears to be built well and thus far, it appears to be able to charge my phone or laptop. Given the price, I highly recommend this handy little gadget.*Note: I mistakenly posted a bad review on this because I didn't have the right cord for it. Mea culpa.

Wall charger is a micro-usb, which is why I gave it four stars. That is not very prominent on the page. Didn't think about wall charging before my purchase because it is solar. It comes with a short charging cord, but would have preferred a USB-C, because that is what my phone uses. Not a deal breaker for me, just one more cord to worry about. If I would have thought about it I would have purchased one with USB-C instead.I have used it for off-grid camping. I hang it on the outside of the tent during the day. Has kept my phone charge for 4 days off-grid (would probably go longer, but that's my longest trip so far). I did wall charge it before the trip. I did not really use the flashlight, because I wanted to make sure I could charge my phone the whole trip.

I had a similar product before and really liked how it worked. I was looking for a replacement and this did not disappoint. You can get several phone charges out of this product.The solar charger is a bonus when traveling so that when an electrical outlet isn't available the sun will give additional charge and longer life to your chargers capacity. The built in flashlight is also a handy feature!If you are looking for something for home and travel this product is a great option.
