Hiluckey Solar Charger 27000mAh 22.5W Fast Charging Power Bank USB C PD Portable Phone Charger with 4 Solar Panels for Cell Phone Tablet

Don't let them tell you you need something more expensive! Everybody told me this wouldn't work, but my sister bought one and hers worked great so I went ahead and got the same one she had and mine worked great too! We both took hours on a four-day hike in upper Michigan and these bad boys charged everything we had the whole time. When we stopped, we open them up and set them in the sunlight and we were good to go! My sister walked with hers open on the back of her bag. If there's no sun, you're kind of screwed, but we were good for at least 2 days before we needed to charge these packs. I would recommend.

Ah, the marvels of modern technology never cease to amaze me! I recently had the pleasure of acquainting myself with a device that can only be described as a pocket-sized powerhouse of electrical energy. It's a little like carrying around your own personal thunderbolt, except with much less risk of being struck by lightning.To be perfectly honest, I was initially skeptical of this contraption. I mean, a power bank with built-in solar panels? And all of it an such a compact package? Come on!Now, I won't bore you with the technical details, but suffice it to say that this little gadget can deliver up to 18 watts of power to compatible devices (yes, it supports USB Type C Power Delivery) - which is frankly more than I ever expected from something so compact.And let's not forget about those folding solar panels, which seem to magically soak up sunlight and turn it into usable energy. Although, and that's one strike against this little box, there is no way to tell, how much power those panels actually produce. I wish there would be a little LCD, which both showed the rate of charge and discharge. But maybe that's an engineer talking in me.One of the things I appreciate most about this device is its build quality. It feels sturdy and well-made, like it could withstand being dropped from a moderate height or being stepped on by a particularly clumsy elephant. And the fact that it can fit snugly in a larger person's jeans pocket means that one can take it with anywhere, whether they are exploring the great outdoors, taking a transcontinental flight or simply commuting to work.All in all, I must say that I am thoroughly impressed with this little marvel of modern engineering. It's like having your own personal power plant in your pocket! I wish I had this power bank when I was climbing mountains in 2000s!

I purchased this to replace an older model, the HI-S025, which worked quite well on frequent camping trips for 4.5 years. After a few years one of the USB ports had quit and the other works about 80% of the time. I usually charge it in AZ sun, adjusting its position to get maximum sunlight and it goes from half charged to full in half a day on average. It charges my iPad mini from about 65% to 90-100% in a few hours. I find it best to charge one device at a time. The new model is a bit chunkier, has a better position for the popper to lock it closed and has a slightly bigger battery. It is recommended to fully charge it from a wall outlet before first time use, and again every three months. I advise against putting it on your dashboard inside the windshield of your car, since it can get much too hot and cause buckling of the material. If the new one is as good as the previous one, I will be very happy. It also comes with a small carabiner clip, perhaps to attach to a backpack. However, the only place of attachment would be the popper that keeps it closed, and I would not trust that given the weight of the device. It also comes with a charging cable, which as per the previous one is extremely short. For some reason they shrunk the specifications that are printed on the device down to microscopic level which you would need a magnifying glass to read. I will update as I get to use it more.Note…After a few hours of use, I discovered that one of the USB ports only works with 2 of my 6 charging cables.. the other port works with 4 of the 6 cables. All 6 cables work with wall chargers and a 330 Watt large power pack. So this charger is VERY FUSSY ABOUT WHICH CABLES WILL WORK WITH IT. I’ve purchased some more cables, but I don’t feel I should have to when the cables I have work fine with wall chargers and other power packs. I contacted customer service at the the seller and, after I provided photos of the problem, they gave a full refund without needing to return it. This is good service and means they will not try to resell a faulty device. I added back a star after subtracting two.
