i bought this item a while back but never had use for it until last night when my power went out. the flashlight will not come on even if fully powered. the charger powered up my phone for 36% and the power bank died. smh.very disappointed.

I bought this item well over 3 years ago. Sadly today i went to use it and the battery inside expanded to the point where it looks like its going to burst... though that aside i give it a decent rating as it did last quite a lot longer than some other packs ive had before

Love these so much. I use mine all the time. I got one for everybody for Christmas. Everyone was so happy, especially the campers in the family. I always keep mine charged I can get about 10 maybe more full phone charges out of one full solar charger. This is so worth having if there are multiple people around or if you are outside.

works good, but just be aware that it dosent have a Type C OUTPUT, that type C port will only input power while the other USB ports will output to any other type of power supply. so if your charger has a starting end of USB C that outputs to USB A/B or a DC charger, you will need an adapter. but if you're using this for phones and not a laptop like me, you will be completely fine and everything works very well. overall this product is great, just be aware of what charger ends you have, there is no typical USA wall outlet in this travel power bank, so you can't plug things in that only have a charger with a wall plug in. but thats not normally a problem as most things take USBs anyways

WARNING!!!This product is terrible and does not match the seller's description.I bought 6 units of Power-Bank-Portable-Charger-Solar - 36800mAh Waterproof Portable External Backup Battery Charger Built-in Dual QC 3.0 5V3.1A Fast USB and Flashlight for All Phone and Electronic Devices (Black), which I was very disappointed with. The information on the Amazon site from the seller does not correspond to the truth (perhaps it was presented on purpose to mislead buyers).On the website, the product description states the dimensions to be 10.55 x 6.18 x 1.34 inches, but the actual size is 5.51 x 2.95 x 0.79 inches, which is almost 2 times less than the description on the website.Regarding the 36800 mAh, my Xiaomi phone has a 4000 mAh battery, but it only charges it about 1.5 times, so the volume of the product will not be more than 8000 mAh, which is confirmed by the almost 2 times smaller size of the product.The flashlight does not have the lighting efficiency as stated by the seller.This product does not meet the characteristics specified by the seller on the Amazon website, which misleads buyers.I do not advise you to buy this product because the information displayed by the seller is false.I ask the Amazon administration to pay attention to the seller's posting of false information about the product, which affects its image.

Thanks to severe ADHD, I’m incredibly forgetful, I never charge anything, I’ve always got a low battery percentage on pretty much everything I own and that includes power banks.To mitigate this issue, I ordered this little guy thinking “hey, it’s 20 bucks, why not”Well, thank the gods I did, I set it out in my sun room and forgot it existed until today when the power cut out unexpectedly during a storm.I’ll probably end up buying one of these for every room and person because it’s currently holding my little neuroatypical family together at the seams during a lengthy power outage.It’s charge my phone fully from 3% to 100 relatively quickly and been a flashlight that got us through bath night, it’s been powering usb fairy lightsIt’s 4 hours later and I still have about half of the battery life on it left.Don’t hesitate to hit buy now. It’s a “set it and forget it” piece of equipment and it’s TOUGH. I’ll recommend this particular one until the day I find anything better suited in the same price range.

I bought this product mainly for the compass. I own many USB chargers and this charger has LED flashlights (pretty bright) and a small compass as well as two USB ports for charging electronics. CAUTION: the instructions in the manual state this charger cannot support all-in-one data cables to charge multiple devices. It says do not use one. This charger charges by sunlight, supposedly, but I have not tested this . Please read the instructions. The instructions were all over the place. It' stated in the product's description that the batteries in the charger are "high-density lithium polymer batteries," but it also gives a WARNING in the product booklet/leaflet that, "This product contains lithium-ion batteries." Which does it contain, lithium polymer, lithium-ion, or both type batteries? I looked up the differences in the batteries, so they are different types.I almost returned this product based on the Precautions section of the product's booklet/leaflet:"Do not drop or use this product in high temperature, humid, strong magnetic environment." It has solar panels for charging by sunlight. It states in the product's description that it's waterproof-why can't the charger be dropped in water or be in humid areas? There is what appears to be a waterproof cap covering the USB ports."Do not place foreign objects such as metal onto the wireless charging area to avoid danger" There is no wireless charging area. If there is one, mine does not work and I should get this product replaced."Do not leave this product in the car, the closed high temperature environment will cause damage to this product." The purpose of the solar charging is to be placed in the sunlight. I guess it's best to place it in sunlight when it's cold not hot or humid as in the summer."This product has a built-in over-temperature protection function. When the ambient temperature exceeds the normal use temperature range, over-temperature protection may occur. At this time, just move the product to the normal use temperature environment and click the button to restore the output." Too much going on here. Is the product safe to use in high-temperature environments or not? No, I will not intentionally attempt to use this charger on a day over 75 degrees and you obviously cannot sit it in direct sunlight on a hot or humid day.Under the solar charging instructions in the booklet/leaflet, the instructions states, "Under the sunshine (avoid high temperature) or strong light environment, the solar power bank can charge itself without operation, and the solar-charging indicator light to turn green and steady lighting. Please charging the power bank with adapter when it under the self-protection mode that cannot be used or turned on." All quotations are typed verbatim from product's manual.I am going to use this for the compass because I specifically bought it when I saw the compass. I thought the product was larger, but it's smaller than I expected-fits in my hand 6 to 6.25 inch hand. The best parts about this product so far are that the LEDs are bright, the charger was fully charged when I received it, there is a waterproof cap, but I am concerned that getting this product wet will cause the internal batteries to swell and spoil the product. It may be worth the $19.99 spent, or it may be an overall dud, too. I am leery if the charging is actually 36800 mAh; I am suspicious that this may be an ok but not an excellent product. I wish to return later to say better things about this product as I use it more.UPDATE: image included
