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

SAFARI SAVIOR: During a trip to South Africa, I needed a portable, flexible way to charge a variety of batteries in a bush camp without power. After lots of research, I found this foldable, relatively lightweight solar panel and it earned its cost and is now an essential part of my camping and photography gear.PROS: It had the key element - direct DC output to marry up with a DC input (TSA) approved CPAP battery. As well, the USB C output worked to charge a power bank for my photo equipment. In SA’s June winter sunlight, I managed to get everything recharged without drama for 4 nights. It comes with a dump truck full of cables, but I mostly relied on my own.CONS: The breakout box with connectors seems cheap. The DC connection feels sturdy but the USB C feels loose on the circuit board beneath the plastic housing. I fear it may last long.It does not seem to handle simultaneous outputs. When two cables were plugged in at the same time (DC and USB C) only one would charge anything. Make sure you sequence your charges wisely. The hardware for hanging and attaching is ok but I will replace the included plastic carabiners and I supplemented what's included with my own rubber twist ties that turned out to be invaluable for getting it attached to anything at just the right angle.TIPS: If you are going to rely on this charger for critical equipment practice your setup in the backyard before heading out. Run everything you'll charge down to 0% and see how your setup works, what's the best way to hang the floppy foldable panel. I did and as a result, avoided surprises in the field.Like all solar, its max rating is under unrealistic ideal conditions you're unlikely to replicate camping. Before cursing the panel, mind that you have cables rated at 100w to maximize your charging otherwise *you've* created the bottleneck that limits your input wattage, not the panel. I pulled 50w regularly, which was more than sufficient to recharge 1 CPAP & 3 Canon R6 batteries along with 50% of a 24,000mAh Anker power bank.It is foldable so you'll need to attach it with tension if it's above the ground. You'll need some line or twist ties to supplement the included carabiners.Don't leave it out at night or the hyenas will rip it apart...probably not a concern for you. 🙂FYI - this worked great with the Medistrom Pilot-24 Lite CPAP battery, a TSA-approved DC input/output CPAP battery and I was able to power my ResMed Airsense 10 for 4 nights without interruption

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.

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.
