Customer Reviews
Great little charge controller!
Compared to some of the Renogy controllers I've used, this POWOXI Solar Charge Controller 20A does a fantastic job. I picked it up during a holiday sale and got a nice automatic discount. It's working perfectly for my setup, keeping everything topped off while I'm out and about. 👍
Decent charger for the price
Got the 20W Solar Charger for my fishing boat. It does the job, keeps the battery from going flat between trips. The suction cup mounts were a nice touch, made it easy to stick on the windshield. Didn't have any issues with shipping, came pretty quick. Overall, I'm happy with it. It's not super fancy, but it works as advertised and that's what matters to me.
Keeps my RV ready to go!
I absolutely love my new RV Solar Maintainer from POWOXI! It was so easy to install, literally took me minutes to get it hooked up. My RV battery used to die after a few weeks of sitting, but now it's always topped off and ready for our next adventure. The quality feels really solid. I'm so glad I found this brand. I'll definitely be back for more gear and will tell all my friends with RVs about it!
Good for my truck
Bought the 10W Solar Car Battery Charger. Works fine. Keeps my truck battery charged when it sits. Easy to set up. Fast delivery too.
Reliable as always
This is my third purchase from POWOXI, got the 50W Solar Panel this time for a bigger setup. Just like my previous 10W and 20W chargers, this one is solid. They're consistently good quality and always arrive fast. I trust their products to keep my batteries healthy. Never had a problem with any of their stuff, which is why I keep coming back.
Works well, minor issue
I purchased the Foldable Solar Charger for my camping trips. It charges my power bank pretty well, especially on sunny days. The folding design is super convenient for packing, which I really appreciate. However, the included extension cable felt a bit short for my needs, I had to buy a longer one separately to position the panel optimally away from camp. Delivery was quick, arriving in about 4 days. Overall, it's a good product for the price, just be aware you might need a longer cable depending on your setup.

Anyone know if POWOXI does military discounts? I didn't see anything obvious on the site.
Are POWOXI panels legit? Or is it one of those brands that pops up and disappears?
Thinking of getting one of the solar maintainers for my boat. Are these things actually waterproof or just 'splash resistant'?
hey, was looking at the 20W solar charger for my truck. any idea how long shipping takes to like, Seattle?
Can you stack coupons on POWOXI? I have a first-time buyer one and saw a sitewide sale. Wondering if I can combine them.
