powkey30W Portable Solar Panel, Foldable Solar Charger with QC 3.0 USB - A USB -C & DC Output, Solar Battery Charger for Portable Power Station, Power Bank, Cell Phone, iPad, RV, Camping, Hiking

I like how portable this solar panel is. It's light weight and is easy to carry. It's generates decent power for it's size.The DC output is rated for the full 30 watts but the USB connections are only 15 watts each.I was able to get 24 watts DC testing with my Bluetti solar box. That's a realistic real world output since most solar panels generate about 80% of rated watts. I got 14 watts from the USB C and 8 watts from USB A at the same time. Again not bad.I plan to use this on long canoe trips to charge the batteries of my portable chargers for phones and cameras. This will set nicely on top of my canoe cover while paddling. It's exactly what I was looking for.

3 separate panels are held together by a heavy cordura nylon material. The 4th panel with no solar cells contains a storage pocket and the electronics for output with 3 ports - USB-A, USB-C, and a 5mm jack for the supplied cable.There are 10 adapters included that go into the included 5mm cable.They are labeled K I A B C E H F G I but I couldn't figure out if they were labeled or measured to any standard.For example, the "K" measured 7.9mm x 6mm with a center pin (outer and inner diameter). This (K) fit the input jack port on my Jackery, but nothing fit my laptop. There is nothing about the adapters in the "User Manual," (one folded piece of paper).You'll have no problem if using your own USB-A or USB-C output cables to whatever device, but the 10 jack adapters are hit or miss as to whether one will fit your jack port.With the cable, adapters, and 4 small carabiners it weighs 2lbs 1.3oz (33.3oz) (2.08lbs) or 944g. Not the lightest but much easier to handle than a 100 or 120 watt metal-framed rigid panel as it all folds down to a 9.75" square package (24.5cm) that's 1 1/8" thick (3cm) at its widest, and can be stored and packed easily.There are 4 metal grommets for the 4 mini-carabiners to facilitate hanging for best sun exposure if there's no table to just lay it out on.The pocket and the panels close with Velcro.If size is more important that total watts, this will get the job done on a sunny day (or two). If you have large items to charge, such as a 1000-watt power bank battery, it won't keep up but can slow down the whole discharge. 30 watts under full sun isn't bad for its size, just be aware that it may take time. For smartphones and tablets, this can quickly top up the battery.4 stars - Need more info on the adapters, such as what they're supposed to fit.

Panels have a bit of heft to them, but the fabric weave and stiching appears to be thick and tight so not expecting any wear and tear signs anytime soon. The stitched pocket is a nice touch to store cables and everything folds slim for easy transport. Keep in mind, its only going to max at 30w for pull so while it would work with larger power stations- it'll start to feel like trickle charging compared to smaller power stations which will be a bit more efficient in terms of how much power is coming back in vs the power draw of devices connected. This was tested with a small 84wH power station that had a 100w laptop plugged into it while on the road. We were able to get a good extra few hours on the laptop depending on use and when we got peak sun coverage. For the price, its pretty nice.

This charger is very lightweight and portable. I put it in my back pack and didn't even feel much difference. It packs away nicely when needed with velcro in all the right places.It has a USB-A and USB-C port for charging two devices at once. It takes a few hours to charge, but the idea is to have this hanging either off your backpack while you are trekking (easily done with the included caribeniers.Made of solid material, has a nice carry pouch for all the accessories. Great value for the price too!

I'm not the kind of person who goes camping or hiking, but I really wanted a portable solar panel for being able to charge various devices during a powered outage. This is perfect to have on hand for that. I've already tested it out and it works great. The second I started opening it up outside (and it was even a bit overcast), the power light came on. I set it up on my driveway and tested it out. As soon as I plugged either my iPhone or iPad into it, they started charging. Awesome.
