[Upgraded] 30W Solar Charger with Kickstand, BigBlue SolarPowa 30 ETFE Solar Panel Charger with DC, PD 20W USB-C and USB-A, IP65 Waterproof, Compatible with iPhone, Samsung, iPad, Small Power Station

This is a well made little solar panel that charges very well and I believe is made of the more advanced monocrystaline silicon material. It charges as expected and the digital read out is a big plus!

It’s solid. On the bright sunlight it charges two devices with 2.3-2.4 amps. Good enough to recharge two 10000 mah power banks within several hours. We took it to Yosemite and it did the job. I didn’t take it on the hike, not sure it would work well when attached to the backpack - the angle of the sunlight wouldn’t be good. Works perfectly if you leave it in the camp though. While we were hiking it was completely recharging our power banks.The main con is that if one of the panels is in the shade, the charging is closed to zero. The second one is that the pocket for the device is not insulated and, well, it’s black. So if you put your smartphone there, it will be overheated within a few minutes and will stop charging. At first I think it didn’t work properly though, so here a few tips that I’ve figured:1. All the panels must be exposed to the sunlight. Even a small shade on the panels affects efficacy dramatically.2. It’s better to use with powerbanks rather than charge your phones/tablets/whatever directly.3. Whichever device you are charging, keep it off the sun. The pocket on the solar panel itself doesn’t work at all, and if your device has any overheat protection, it will stop charging pretty soon. If it doesn’t have a protection, it can just explode if the sun brights really hot. I was putting the solar panel on a camping chair with insulated pocket for a cold drinks and putting my power banks in the pocket. Works pretty well.4. If the sunlight is good, there is no need to try to sustain the good angle (the closer sun rays fall to 90 degrees, the more power the panel will generate). But if it’s not very sunny, try to put something under the panel to keep it directed towards the sun.With that, I think it’s a pretty good solar panel, if you know the above and understand how to use it.Be safe outdoors!

Great product very easy to use, affordable, great for camping or hiking. Solar charging this product takes time doesn’t necessarily need to be in direct sunlight overall great product to use when camping. Highly recommend.

The first thing I noticed on unboxing is that this panel folds down very thin and more neatly than the previous charger I was using, which was a 14 watt made by Anker. This one is virtually the same size and has a very neat and thin feel despite the somewhat thick built-in ammeter, which is the main reason I chose this one. The second thing I noticed is that it had 'new car smell' which faded quickly but was nice. The pouch seems well designed with a good quality zipper with a rubber pull nub and elastic straps inside. I don't intend to use the pouch often but it's good to have and is convenient for storing cables. It came with a short cable and I supplemented that with some very short cables and a longer one for charging my phone at a distance so I can stay in the shade. The little hanging loop between the four panels and ammeter/pocket section is very handy for hanging it in a window early or late in the day.The main reason I wanted this product was to charge devices while staying at a mountaintop cabin which turned out to be a foggy and overcast weekend. Before heading there I tested it in the field on a couple of small islands and at home on a day when there was full direct sun with no clouds. On the islands there were some clouds and I only hooked it to some power banks I use while traveling. The charger is very easy to stow. I slipped it into a 2 1/2 gallon zipper bag, which could hold two of them or one and my large tablet, and folded it over as protection against water while heading there. It was easy to rig. Just propping it up on driftwood is easy but the carabiners that came with it don't seem especially useful. I carry some short loops of bungee cord that are handier for hanging it up. I don't intend to lash it to my backpack as I know some hikers do. Where I hike there are generally trees overhead and inconvenient sun angles. I've tested it in overcast conditions and it still puts out a few tenths of an amp without real direct sunlight.The ammeter is very handy and eliminates the mystery of whether something is really charging and how fast if it is. I notice that in full sun the amps being delivered is highly dependent on the device(s) connected. Some of the older power banks I have don't seem to accept more than half an amp at a time no matter the level of sunlight so even with two depleted banks connected the current only goes to 1.0 or so. With a different pair of packs it goes to 2.0. While testing the charger in full midday sun for the first time I hooked up a large tablet that was down to 28% and with one of those banks the current went to 2.4, with a different one 2.8, and it charged in less than two hours along with the power bank. This was using a short charging cable with the tablet in the shade. Don't leave your devices in the direct sun. I'd generally recommend not using the zipper pouch in most cases too. It gets very hot inside but in some situations you could hang the panel by the little loop in the fold between the pouch and panels and have the pouch facing away from the sun.The red LED display is a bit hard to read in sunlight. Maybe green LEDs or an e-paper display would be more readable. That's literally my only gripe with the thing. A bluetooth device with an app that graphs the charging curve and pops up a notification when something is done charging would be nice too but I think I ask for too much. Overall this is well worth the price and a five star review. I intend to use it for years to come.

I did too much research before landing on this one and I think as long as you temper your expectations on what a portable solar charger like this can do then you'll be really happy with this one. The construction is high quality and the digital ammeter is a really nice addition as it helps you position the solar panels for the best charging speed.

Carga un battery bank de 30,000 mA en el mismo tiempo que se carga en el enchufe de la casa. La calidad de los materiales es muy buena.

Lo uso a diario y va muy bien. Cargo 3 aparatos a la vez sin problemas, como por ejemplo Movil, tablet y powerbank.

Qualità un po' scarsa ma carica molto velocemente anche a novembre

C'est ma première expérience avec le solaire portatif.Mon idée était de pouvoir recharger à minima en même temps 2 téléphones voir aussi une powerbankCe que je constate:- très rigide donc avec le temps je pense que pour le déplier cela s'assouplira.- quand l'exposition n'est pas suffisante la lumière latérale bleu clignote en bleu/rouge.- impossible de connecter 2 téléphones en même temps : 1 sur l'USB-C et 1 sur le micro-USB: le deuxième connecté arrête la charge du premier. Je pense que seul 1 câble en Y peut fonctionner- idem avec 1 powerbank (Anker 325 ou Charmast Batterie Externe 10000mAh) + 1 téléphone: mes powerbank ne permettent pas d'être rechargées tout en chargeant un équipement--> je vais regarder si je trouve une powerbank qui permet cela :-) à priori il faut que la powerbank ait la fonctionnalité "passtrough charging"au final je suis mitigéje reviendrai compléter mon commentaire après d'autres tests
