This product was a fairly straight swap for lead acid battery replacement in my 48v ezgo rxv golf cart. This product is light weight. There is lots of power for what I need.

I already own a Rocksollar 500w and it works so well, I purchased the smaller 300w inverter. We have a lot of and frequent power outages here on the coast. Using a simple "on off" power surge bar. (no lights, no usb or extra items on the power bar). I was getting 3 days out of the 500 and estimate 5 days now using the 300w before 50 AH bat recharge. It is running wifi, full sized desk phone, cable modem and cable phone data box. Don't forget to install a bat disconnect switch for ease of battery swap!

Wow, what a great little inverter. I have been using it for 2 months now. First to power my smart tv, power bar, surround sound speakers and occasional cell phone charge. Great, by placing the inverter on a glass plate (to absorb heat); the fan doesn't come on! So noiseless during use!. High quality, solid build, and even better customer service. Does higher power consumption if the battery is not disconnected, due standby usb. Installed a battery disconnect switch; prolem solved!

Inverter is powerful enough for my Keurig, i am waiting for the remote controller as it was not in the box.

The day I got my unit in, it was put to work immediately due to a power outage. It provided light, power to my laptop to keep working, and i charged my phone, headlamps, other power banks, camera and use it to run my small shop light. It's coming with me on all my future camping and overlanding trips as well. It had a 3/4 charge from factory.

Amazing customer serive, Fast shipping. Very well packed items. Love our Rocksolar Battery, Inverter and Solar panel

Good for everything I need off grid. Rechargable batteries, fans, lights, phones, health watch, laptop, even my 42" TV and 5.1 surround sound system, without the heavy gas pig generator. Even got two solar panels for it. With the right plitter and extention cables i can draw in two panels vs one. And the panels can directly charge your devices right from the sun too.

The ventilation in the hospital was really good as it turns out, but the RockSolar kept my DIY small Corsi-Rosenthal air purifier running so I was even safer from COVID. No one even asked what I had LOL. I look forward to using this set up in other medical/dental appointments. Previously I have had to ask for my air purifier to be plugged in. This is way better. And I can carry the air filtration while it is on!!!!

I have over 2,000 COVID-cautious Twitter followers and will tweet about this. I originally learned about the RockSolar on Twitter from COVID-cautious folks.

I recommend setting up faster delivery with Amazon if possible.
