Works as promised. Love the bright green ready light!
Portable, easy to pack, easy to carry. You do need to unfold the first level, and then flip the panels open. The picture is the result. The Suaoki charged up, using the BigBlue panels, after 4 1/2 hours, the panel is folded, and the Suaoki is now charging my phone. Yay!

Met my expectations
The panel is well packed when shipping to us , no serious defect but the velcro is curled up and unable to close firmly. (So minus 1 star for this)The panel work fine , it able to charge my little power station perfectly at a cloudy day. I don’t know is it possible to fully charge a bigger power station. But it still met my expectations.The size is very compact , very easy to carry around. But because of it’s foldable design , it unable to stand upright and facing towards the sun on it’s own , it is the only concern.

Kept things charged in rainy weather.
I was trapped by weather at a remote lighthouse with some friends for several days. Although it was cloudy and rainy, this panel still put out a continuous 10 watts, which with 10 hours of daylight was enough to keep several phones and a laptop charged with moderate to heavy use. It did an awesome job.The panels themselves are pretty much waterproof, and the electronics that isn’t waterproof is in a pouch that closes up to keep water out. So it was possible to just put a power bank in it and leave it charging out in the rain.One thing to beware of is that an older power bank got fried by it. I think that it was because I’d plugged it into the USB-A port that can do quick charge, and with some intermittent light the solar panel got confused by the quick charge handshake and put out 9volts, which is too much for an old power bank. So make sure you plug older equipment into the USB-A that’s limited to 5 volts.

Great for charging portable lithium battery packs
Very portable and well made. Easy to setup and use. I just laid it on the ground. In full sun it output around 85 watts. Dropped to 60 watts when cloud passed over. I am sure I would have got more efficiency if I had took time to setup the right angle. But that is the one downside to this panel, it does not come with a stand. So you would have to get creative to align it properly. Otherwise, very happy with the panel.

Waited long enough for this!
Compact 100w folding multi voltage solar panel. Charges 12v batteries and USB devices. Surprisingly durable and a bit hefty for it. High performance quality. Big enough for practical power for solar generators. Wanted this a for a very long time! Affordable.

Power Output is only 9 watts from usb C which usb c is normally higher but not high enough from a supposed 25 watt panel. I’d expect at least 11 watts from this setup, but nope, just 9 watts max.There is far too much stress and strain when folded properly. That may create a longevity issues.For 9 watts, this is junk bc of the price point. Unless you absolutely have a reason for the shape and size, then maybe. There are plenty of 10 watt panels out there for way less.

Couldn’t get more than 5-7 watts out of this panel, something is wrong with USB C power handshake
I wanted to like this panel, I really tried. I live in Florida so we have a lot of great sunlight all year round. I’m going on a backpacking trip in New Mexico (Philmont) with the Scouts and I need a good panel to charge my phone and other gear. I had a UT658DUAL USB Tester made by UNI-T hooked up to both the USB A & C ports. The USB A would only deliver 7 watts. When trying USB C, I would watch the amps climb as high as 3 maybe a smidge more at 4.7 or 5 volts (15 watts) but it quickly dropped down to 1.16 amps at 4.58 volts which is only 5.3 watts. I think this panel wanted to deliver more but it couldn’t negotiate the handshake properly on USB C with 3 different battery packs (which will be the main use of this panel while hiking in the sun). The worst thing I discovered is that if you covered even 1/2 of one of the 8 fold out panels the whole thing stopped charging, that was depressing. I was testing this against the FlexSolar 20W panel (which outperformed this one but suffered from the same cover a portion of the panel and all stopped working problem) and the SunJack 15W panel (the clear winner as it still provided power if you covered one of the panels, just reduced by the percentage of panel covered). I tried contacting customer service about this problem but they didn’t respond (only email support provided). I can not recommend buying this panel. Please spend the money if you can afford the extra weight and get the SunJack brand.

Ich habe mir die Solarplatte zusammen mit einem Akku für meinen Bulli gekauft. Sie funktioniert einwandfrei. Als Kritikpunkt lässt sich nur die kurze Kabellänge nennen, wodurch ich dazu gezwungen war, mir ein Verlängerungskabel anzulegen. Sehr positiv finde ich die kompakte Größe im gefalteten Zusagen, sowie die vielen Anschlussmöglichkeiten

Most foldable panels are bottlenecked by the types of connector you attach to the panel. E.g if you buy a 60w panel with only two USB connectors you can only pull 5 watts out on each port. In the case of this solar panel, it supports USB PD and can deliver 60w out through that port and less concurrently through the other ports. Even in cloudy conditions, the panel has easily delivered 30watts to a Li-on battery via the USB-PD port. I’m also delighted that most the of the panel is entirely waterproof – you just need to shield the connector box from water (excellent for camping). Overall, a worthy investment and a significant step forward from previous technologies.

Pannello solare ottimo, di livello quasi professionale, unisce grande potenza ad una grande semplicità di utilizzo grazie al supporto delle più attuali tecnologie di ricarica usb e grande versatilità grazie al fatto che è pieghevole in 12 parti e di dimensioni abbastanza contenute in rapporto alla potenza di 100 watt.Anche il peso di 4 kg non è eccessivo in rapporto alla potenza ed è leggermente inferiore alla media dei prodotti dello stesso livello.Quello che sorprende è il potenziale veramente elevato che è difficile sfruttare a pieno perché è difficile trovare delle batterie che supportino una velocità di ricarica altrettanto elevata.È possibile ricaricare fino a 4 batterie contemporaneamente, io lo uso con una power station da 41200 mah e con 3 power bank di varie dimensioni e in condizioni di sole pieno ricarica tutto in meno di mezza giornata.In particolare se collego la power station Litionite Riden da 41200 mah al connettore Power Delivery con un cavo usb type-c compatibile con la ricarica a 100 watt, in condizioni ottimali, si ricarica da zero al 100% in meno di 3 ore !Queste caratteristiche secondo me giustificano il prezzo un poco più alto rispetto altri prodotti simili.

コンパクトに畳めるので持ち運びは便利ですが見た目よりは重く感じます、またソーラーパネル部分はどちら側も同じ見た目なのですが、青い端子部分がない方出ないと日を受けても充電されません、それでも持ち運びしやすいし、持っておくと便利だと思います。

2/24 10:20 に窓越し平置き状態で、5v 0.4a 2w で発電することができた。災害用に買ったので、テキトーな設置だけど発電できることが確認できたのでOKです。
