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)

Great quality, compact and foldable, even through light clouds it has good power output. Will charge from inside vehicle window. I use it for phone and drone batteries.

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!

I have several portable solar panels for different occasions and purposes but, the one thing that separates this one from others is the handy pouch to carry a battery power pack and cords. This 28W panel is also compact enough to strap onto a backpack or place inside. With backpacking, any added weight is not desirable but, if you’re going to be roughing it for a few days or more in the wilderness and need a power source, then this would be a good contender. BUT, if you are going to be where there’s going to be an issue with having enough direct sunlight for effective solar charging then maybe taking several power packs would be more effective and logical. I like this solar charging panel and its portability. The output reading is bright enough and easy to see how much sunlight you’re getting and it does have two USB slots for dual charging capabilities. The only thing I do not like is the lack of a Type C port. I’m assuming it has to do with the type of solar power converted they’re using so it’s not a deal breaker for me. Hopefully they will come out with an updated version, which I would gladly buy IF it’s not too much more expensive. Overall I like this portable solar power charging system and the quality of the design and materials is pretty good. So, if you’re into backpacking, hiking, camping, or prepping then I recommend it. Other than hiking and backpacking, this panel is also part of my bug out gear list. You never know when you gotta make a run for it…

This solar panel works as advertised. I'm not entirely sure how accurate the LED screen is with the power its receiving, but it does charge the power bank I have within a decent amount of time (approximately 2.5 to 3 hours). The system folds up and secures your accessories, saving hella room for additional gear. I have the entire system (solar panel, power bank, cord, tri-pod, lamp) attached to the back of my battle belt. Definitely take the time and spend the money on this addition, completely worth it.

Super cool, very cleverly designed. Works well. Instructions are in Japanese. Only reaches advertised charging capacity with both ports being used. Minus one star for price, way too much when compared with competitor products.

Very high quality for the price paid! Solar panel seems to be pretty efficient. I like the design and how everything is well thought out.

The instructions were in Asian languages. If you only speak European or African languages, throw the instructions away. The digital indicator is a nice feature as it allows one to see the amount of power it is sending to the item you are charging. DO NOT FORGET TO GET A POWER PACK as it doesn’t store the energy for later. Lastly, the stand took a minute to figure out but it is simple once you understand it. The case is padded and built in. Great for travel to remote places. It appears to be better built than others I have used.

It's everything all the other 5 star reviews state, but one thing that was not as accurate as it could have been was the claimed weight. I weighed it on my precise digital scale 870g vs the stated 771g. So it does feel a bit hefty for backpacking and bike touring. That said, I don't I'll ever run out of power again given the total surface area on the 4 x solar panels. There's a lot of solar panel here for a portable unit. It's incredibly well designed, in Japan, although it's made in China, so hopefully it'll hold up in on the trail and on the road. And for the price, out of the box, it seems like a good value. Also, as noted, it holds perfectly the 15k battery (or any brick in that size category) with a protected, zippered pouch. Thoughtful!

Abit pricey but it's good quality and works really well

Pannello compatto e modulare per il sistema nestout, la potenza di carica non è elevatissima ma sufficiente a garantire la ricarica in tempi decenti. I piedi modulari permettono di orientarlo sempre con l'inclinazione corretta e di adattarlo a ogni superfice, inoltre la qualità dei materiali è molto buona. Consigliato!

Love this product line looking forward to using when camping

昨今二次電池仕様系がおおいですよね。あれ便利なんですけど充電がなくなるとどうしようもないですよね。。キャンプ行ってるときとか、災害があった時にバッテリ残量気にするのもね。。モバイルバッテリ持っていても結局は容量は限られている訳でして。 デバイスが電池式（一次電池）であれば電池を”買う”という選択肢がありますが、二次電池は何もできない。 これスペックのとおりです。これと同メーカー製のバッテリがあれば、いつでもどこでも（夜中以外）充電可能です。 あと製品として作りが非常によろしい。 お勧め。

bon produit. nécessite une exposition plein soleil pour recharger la batterie. minimum 8h pour recharger complètement la batterie
