Solar Charger 100W Solar Panel Foldable Portable with Dual 5v USB18v DC for Laptop, Tablet, Notebook, 12v Car, Boat, RV Battery, Camping, Hiking, Travel

I bought this not expecting a ton out of it. After all, it lays flat on the ground or it's hung somewhere but in no way is it optimized to catch the sun at the correct angle. It is (technical term here) floppy and standing it up or leaning it against something isn't an option. That being said it does what I expected it to do and it does that well. I average somewhere around 60 watts of output and I've seen as much as 90 watts for short spurts. When I was researching it there were a few reviews that said it was difficult to match up the velcro when you fold it up. The trick here is to press the air of it as you fold it up. If you do that, it's plenty thin enough to get the flap around and attached to the velco strip. The little bag that is on it is fairly useless but it doesn't make things any more or less difficult to work with. I use it at the pool with a 1000-watt-hour power supply that powers a pair of speakers (8 watts nominal 14 watts peak) and the plan is to add a portable fridge to the mix. I can charge anything I want as long as I want, power the speakers, and all the while put more energy in than I am taking out using this panel with that little bit of draw. The USB charging ports on it are efficient and I find that charging from there seems to use less of the incoming power than charging from the power supply. I do notice the output drop a tiny bit, but it's constantly fluctuating and I don't have the sense I'm killing the output by doing that. The ease of flopping it open, throwing it on the ground, and hooking a cable to it cannot be matched. For that kind of completely brainless setup, the output is great. When you have it folded up it's a neat package and it doesn't seem frail or fragile in any way. If you wanted to carry it back packing you could but it would be on the larger end of the panels you'd attempt that with I'd think. I am in no way an expert on solar panels. Logic dictates most of what I know. I would not be scared to try this panel and there is no prior experience necessary to use it how it was intended to be used. The pool is a rough life for anything being packed back and forth and so far I'm impressed by just how unaffected this panel seems to be by all of that.

I bought this with this battery pack (https://www.amazon.com/Renogy-72000mAh-Portable-Generator-Technology/dp/B0791WDZTW). Perfect combo. The solar charger fully charged it up in 4 hours (1 PM to 5 PM on an overcast day). Tested using the pack to run my laptop while charging it (the laptop, not the pack. sadly, you can't charge and use the power pack at the same time). Between the adapters included with both, you probably won't need any others. if you do need something specific you'll want to grab that. it also came with clamps to jump a dead car battery (haven't tried that yet, but i bet it would work in a pinch). One downside is that you can't fit all of the included adapters and cables in the little pocket on the panel. No big deal. i bought a nylon draw sack and tossed that in my backpack for when i need them. these (https://www.amazon.com/dp/B0834LF61W) small ones are the perfect size and you can write on them with silver sharpie. The whole thing fits in my backpack for when i need it camping, but is too heavy for every day carry. I wish i had bought one sooner. 10/10 would buy again.

This review is for the ALLPOWERS 100-watt portable solar panel. First, the cost, I paid about 2 dollars a watt which is far better than any other "portable" solar panel that I have seen. Regular glass solar panels are going for less than a dollar a watt. Second, it is portable and would make a great choice for charging an electric bike battery "in the field" with a DC boost converter. I gave the panel 4 stars in weight because it is over 4 pounds but, that is not an issue since it can be stowed in a backpack with its small size. There is a parallel port to add another panel in parallel for faster charging. There are no MC-4 connectors supplied but, lots of solar generator plugs which goes hand in hand with portable solar generators. I know someone who has one of these and it is still working. Hardly a testimony, but a reason to take a chance on this solar panel.

With how much of a form factor this folds down to it makes it way more portable than larger panels that just fold once or twice. The power output I can only verify from a jackery 300 goes up to 76 watts, but I'm unsure if that's the limit of the jackery input or the solar panel, either way I'm quite happy with these panels, they turn sun into electricity that I use to charge my smaller devices. Do be careful with the cells, if you bend them or step on them you'll hear cracking which I assume is bad. TLDR: Very portable, does a decent job, be careful to not over bend or step on.

Nice Thanks

We have a briefcase solar panel in our caravan which is brilliant but it is heavy at around 10KG This is a 1/4 of the weight and 20W more powerful. I had been concerned with previous reviews but i shouldn't have. It works as well as the other panel we have and has the bonus of it being really small to pack away. My tests on an overcast scottish day were 20 Volts coming out of the unit and the USB reading the Desired 5 volts. It charged my Ipad no problem. It has 2 USB, and a selection of adaptors for any situation. it is quite wide at 3ft but folds away to a about 1ft which is brilliant for backpacks. It also comes with 4 carabiners for hanging on things and there are a number of Loops in the panel that can be used as mount points. I’m off to get a solar controller now to ensure my battery in the caravan doesn’t get over topped up. UPDATE: been installed in my caravan over last 3 months and it hasn't kept the battery topped up as well as my other 80Watt one. I have had to supplement it with an extra Solar panel, Problem isnt the panel as such but the fact i cant get a full flat face to sun angle with the folding design as i could with a rigid panel, i will however say when its laid out on the ground it works fine

Suelo hacer acampadas al aire libre y necesitaba una placa solar potente, pero compacta, y esta fue la solucion, al ser plegable, no ocupa nada y es muy comoda de transportar. Una vez abierta es muy grande y tiene una potencia aceptable, para cargar el movil y la bateria de coche para tener luz por la noche. Ahora en verano, debido al calor, la potencia se ve reducida, pero llega de sobra para el uso que le doy. Incluye pinzas, adaptadores para distintos tipos de portatil, etc.

Werkt goed, compact als het opgevouwen is, makkelijk in gebruik

Bought this last minute for a fishing trip. Jackery runs our 12v fridge overnight but had to rely on generator during the day. Gen only provides 38w for charging. This solar kit charged Jackery in several hours instead of 6+. And once charge ran the fridge through the Jackery and held 90% plus so still had it for overnight use. Plus cell phones, tablet and bluetooth speaker charges as needed. Lay it on truck windshield and pulled 45-75w in northern BC sun. Folds up smaller than a laptop. Totally happy with this unit.
