I bought one a few days ago. Pretty good, doesn’t have any stand, but does have loops on two of the sides to allow hanging.
3% back on SCA giftcards on Cashrewards (can buy exact dollar value) will make back the difference. Discounted gift cards also available at several portals (up to 10%).
No way that's 300W…
"Dimension(Open): 1470x530x4.6mm"
So let's say there's 1400x520 of actual solar panel surface.
With sunlight at 1000W / m^2 and the claimed panel efficiency of 22% the max power possible is 1.4m * 0.52m * 1000W/m^2 * 0.22, or 160 watts.
Even above the atmosphere with 1380W/m^2 that only gets it up to 220W

https://www.cnet.com/home/energy-and-utilities/most-efficien…That product is about 40% the size of today's typical sized rooftop panels, yet those rooftop panels are rated at around 440W.
300W is a bit of a stretch, for these portable solar panels.
Yep,….expect 120W to 150W absolute Max for a few hours in the ultimate best conditions at the
right place in the right season lol.
Hard Kaur ? Bet she is
Doesn't look bad!
Pumps out 17.3 Amps on max working current, so certainly isn't a 'toy'. Could definitely charge a decent size LiPo4 camp battery that's for sure.
The detachable PWM means you don't have to rely on an inbuilt hardwired one…. so if you have a decent aftermarket one like from Victron or something, it's all wired up ready to go with Anderson plugs.
I'm very tempted.

Looked it up on ProductReview. It wasn't a very pretty picture. Some people were happy, but a lot of people were either unhappy with the manufacturing quality, specifically that theirs only produced half the claimed output, or it didn't last long.
Can't expect a portable solar panel to last sadly - they overheat and can't properly cool down
For that price you should expect a mppt controler to get the most out of your solar panels. Note that pwm are dirt cheap and are only ~ 70% efficient. The other important aspect is how well these deal with shade (internal wiring ) some blankets will stop outputting if there is a bit of shade on them (kings 200w), which isn't what you want especially if you are camping.
Price and store in title please.
