ROCKPALS 520WH High Capacity Portable Outdoor Power Station, 500W (95380367)

It pumped up two thick, large air mattresses, kept them at full air pressure with repeated A/C fill-ups over two weeks, kept many phones charged, and restarted an automobile with a dead battery. Two weeks of camping with no recharge. It is the best and most versatile battery I have owned. Thanks to the seller!

Great battery life. Used it to power a queen electric blanket with two regular wall plugs and it stayed on for 6 hours, maybe more but I forgot to check. Feels like a quality product.

Got it with a portable solar panel. Works great by far especially during power outage! Would recommend to have one!

This is a great little unit and very portable and runs my Xfininty Gateway, lights and TV for hours. It charges in about 6 to 7 hours from house current. The LED could be improved like the Rockpals other 500w which is not available to purchase. The bar display is OK, but it should ideally display how many watts being used and how many left. Otherwise, I would have given 5 stars!

It feels very solid because it's heavy (18#). The charger box gets so hot that I was concerned and contacted the seller.
They said it was normal
When I went to test it out nothing worked. I asked to return this and the seller sent me a prepaid label for ups... there were a few issues having it picked up but the seller really did all they could to help me. The higher stars are for the seller. I appreciate them. Now I need to find something that works. I read reviews on this product that were good. Maybe I just got a defective unit. That happens sometimes.

I bought this to use with my CPAP when dispersed camping. I can easily get two nights of CPAP use without the heater out of the 500 wh power bank. Be sure to unplug your CPAP when not in use. Considering buying a second unit as a back-up. Highly recommend the Rockpals because it recharged from 2 bars to 5 bars in a little over 4 hours in the direct winter sun here in Goergia

I was looking at a bunch of fancy-looking 300w stations, even some 500wh stations that put out only 300w capacity. In an emergency situation I want to know that my power station has my back: both in capacity and power. Right out of the box I wall-charged it, stuck a meter on, and plugged in my 800w space heater. On low, the heater pulls nearly 400w. Then I attached my desk foot heater (50w/100w) in the other socket. It has been running both devices simultaneously over the last 45 minutes just fine. The internal fan turned on and I’m watching the power bars go down, but the power station is still chugging away. Also proved it can charge my work laptop through the USB-C PD, though the wattage was under minimum charging specs. I’ll have to keep this little guy.

For the price after discounting, this is a decent solar generator for the supposed 520Wh capacity. A couple of things missing are the lack of numerical display for the amount of charge (5 bars only), and no indicator of charge wattage or time remaining based on current load. No flashlight (no big deal to me). The mentioned features are likely found in more expensive models so as long as it reaches 80% of its stated capacity of 520Wh it is a decent buy purely as a mid-low-end backup generator with decent capacity.
