ELECOM NESTOUT Portable Solar Panel, Dual USB-A Ports, 28W Power Generation Charger for Phone Camping, Durable Water-Resistant Ripstop Nylon, Foldable Lightweight, Adjustable Stands (4-Panel)

I use it as an emergency power source for my small electronics and GPS unit via the rechargeable Nestout battery. Thats right in the wheelhouse for this solar panel.Ruggedness: Seems well put together, and of high quality materials. That being said, the velcro fastened legs used to prop up the device so it can properly face the angle of the sun could be a little more sturdy. You will need a solid surface if you are going to use them. All in all, I like the look of this panel. It just says "I'm ready for the outdoors!".Charging time: It fully charged the Nestout 15k mAh battery from 40 to 100% in a period of about 7-hours. Needs full sun, and you might have to move it around to get the full charging effect. I recommend the 15k mAh battery because you can charge a smartphone or GPS multiple times with it. There is a lighter and smaller version as well, but I like the longer lasting battery power of the 15k.Portability: Packs away easily in most 60-90l hiking packs. With the 15K mAH battery it is a little hefty, but not unmanageable. You can pack the cables, battery, and any other accessories inside the pouch of the solar panel to save space. There is a way to charge the panel as you go, by securing to a backpack but I'm not sure how effective it is.Value for money: You could probably find better panels out there, but I can't argue with the price of this unit. Its priced about right, and fits the need.I love this device and the battery that i purchased separately. With the long term unreliability of the US power grid being a concern of mine, its important to have a backup option. Plus, you can take this wherever you go, even on vacation and have a reliable option to keep your devices charged!

This product works incredibly well I was able to charge lots of devices with it, I don't know how often I will bring it backpacking with me just because usually when I'm setting up camp it is night time so I don't get a whole lot of time to charge things with this unless I'm spending the night in the same place and have time in the morning to charge things. I don't often hang these off my back just because I spend a lot of time in Forest cover when hiking so it's not an incredibly practical thing to take with me everywhere, but if I'm going to be spending an extended period in one place this will be in my pack.

Charges pretty fast for solar, while in direct sunlight it charged my Nestout 15000mah power bank in a couple hours. I just wish it held a charge so you could plug in your devices after daylight. Overall it preformed better than expected even in cloudy weather.

I wanted something for my Jeep that was very compact that would charge small things.This seems to fit the bill very well. I like it so much. I think I’m gonna order another one for another vehicle to keep it in there.

Charged my phone and mobile chargers while camping. Worked pretty well even though it was cloudy

Charged my Samsung A53 to 3% in about 3 minutes on a clear sunny day, early afternoonThe panels seem fragile but I don't know. I don't see why they couldn't be reinforced with hard plastic edges for rigidityThe location of the readout is wasteful of compartment space, when it could be located all the way to one side to accommodate a larger battery bank. Please redesign that!But I will keep it, it works well enough for my purposes (emergency preparedness).

Beautiful product! Works as described.

A couple of hours of sun took my power bank from flashing three to solid four bars and all I did was set it up and left it. I’m good with it.
