Renogy 30W Portable Solar Charger with 2 USB Ports, Foldable Sunpower Solar Panel for Camping, Hiking, and Outdoor Activities, IP65 Waterproof, Compatible with Cell Phone, iPhone, iPad, Samsung Galaxy

lite weight for camping plus keeped all my batterys charged

Even in partial shade generates enough electricity to charge a device slowly. Easy to hang off your tent or a backpack. Folds nice and compact. I bought new 6ft USB-A to USB-C type cables so my devices could be inside my tent (in case of rain, etc). Another great product from Renogy!-m

I have used this solar panel extensively, and it has not disappointed me. NOTE, this is the smallest solar panel I bought

It was time to update my old 21W USB charger that did not support USBC or quick charge. I wanted a bit larger panel for poor or shady days. This was a 4 panel 30W compared to my older 3 panel 21 watt.I liked that this one supported QC for android and PD USB C.Compared to my 21% in a current test it did indeed put out almost 50% more power which is good.This is one of the best USB chargers I have every tried, many that I tried were gimics and not really usable but this one puts out some juice.What I didn't like is that it only had 1 USB "standard" and 1 USB-C output. I wish it had 2 USB outputs + the PD port. And a 12V unregulated output would have been a nice touch for emergency car or other 12V charging.It also was larger than I guessed it would be. Given my old one was 7W a panel x 3 panels, and many years old I assumed this one would be about the same size if it were 4 panels with slightly more efficient panels. I mean to get 7.5W from the same size that was only 7W 10 years ago seems like a low ask. Alas that is not the case. the 4 x 7.5 panel are each substantially larger than my older unit. It;s still nice, and a decent size but lager than i would have guessed, or liked meaning I'll be also keeping my old one when I want small and compact.

Exactly what dad needed. If you’re reading this just send it.

Charges my 20000 Milano power bank in 4 hours in full sun! Perfect for this back country camping power application!

If you are buying this as a portable power supply and it is being moved, ie: on you car dashboard or carried hanging from your backpack (as shown in advertisement), while moving you are going to be greatly disappointed. I plugged in my iPad at 46% while having the panels on the car dashboard getting direct sun and after 4 hrs my iPad was at 5%. Yep, you read that correct, every little movement would stop the charging so the iPad keep going on and off with display and it discharged at a faster rate then it charged. I even let it sit for an hour. Don’t suggest you charge the actual devices like phones and tablets. Instead, charge a backup battery pack and then only charge when in the direct sun with NO movement. It will work then to charge the battery pack then charge your phone and tablets from the battery pack. Will be a good emergency back up source when used that way. The 3 stars are for the product description being a little misleading. It does work well in the direct sun without being moved at all, and will charge a battery pack. Will keep as a emergency source along with other emergency equipment in the car. It is thin portable and easy to use.

In the Tampa Florida Sun in Nov I got 19.1 watts max with this panel in the vertical position. I used a cable matters thunderbolt 4 usb-c cable going into an Anker Prime 99Wh power bank. I ran the Anker Prime down to 75 % to make sure it didn't throttle the charging which happens at 94% or so. This will be backup power for the Anker Prime which will run my Starlink Mini. I do have a 60 watt Jackery solar saga but it's 5 pounds and doesn't have usb-c PD (power delivery) so far this 30watt solar charger is the best taking size, weight, and what I need into account. I didn't test the USB-A port - it's old tech and all my gear is USB-c now or I don't have it. You can clip this to your backpack and keep your phone inside the zippered area so you'll have power on the Summit of Everest!!if you are in a hurricane prone area aka Louisiana or all of Florida this will come in handy
