For the weight/size best deal
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

One of the best USB chargers on the market
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.

Works great
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
