Anyone have any experience with these? It was a toss up between the Jackery 500 and the RockPals 500. RockPals has a decent summer code and along with the honey app, I was able to score the 500/520 for well under the listed price. Looking online the only reviews are from the 500/540wh ones but those are sold out and they seem to be moving on to this one. There is nothing online as way of reviews for this one. Hopefully it shows up before my trip so I can throw my review of it up here.
I received the unit the other day and set out to see how long it would power my ARB fridge. I charged the Rockpals 500 to full and plugged my fridge in on the DC side first. I have set the fridge at 26 deg. and it was already pre-chilled. My garage was about 80 deg. The Rockpals 500/520 is not 12 volt regulated and I set the fridge on the hi setting for the fridge shut off. The Rockpals lasted just over 24 hours before the voltage dropped enough to get the fridge to shut down. The battery level was still showing 80%. I hit the power button on the battery and it powered the fridge back up however about 10 minutes later, the fridge powered itself down.
I then switched it over to the AC outlet and let it run. The unit made it almost 20 hours on the DC inverter before the battery died. I didn't get this thing to solely power my fridge, I did want something to switch the fridge to on camping trips with my trailer. I also wanted something to act wiring in an aux battery to the truck but be able to move it between my trailer and truck. So far I like this thing but my biggest con is the lack of pass through charging. It would be nice to be able to charge it at the same time as using it. Being 12 volt regulated on the DC side would be a nice bonus but it wasn't a deal breaker for me.
