ATEM POWERSmart Battery Box 12V with USB/DC Port/CIG Socket/Anderson Plug/Voltage Indicator for RV battery box Camper Marine marine battery box for RV SUV ATV Camper Truck Car (Battery Not Include)

I used some pieces of starboard to fit around my 20 AH lithium battery and got a great fit. It has all of the ports and plugs I was looking for to make it extremely versatile. One critique however, at this price point I would expect the USC C and mirco USB ports to be properly aligned so you don’t have to wiggle and prod the plug into them.

Box is a bit flimsy. Lid is also prone to slamming open due to its weight. I'm afraid the hinges will break at some point. There is also no viable way to strap this down if you wanted to.

I like this item when I first bought it but now after owning it for only 4 1/2 months, it stopped working. The digital power level screen doesn’t display the power level anymore. I am unable to read the level and it seems to short out. When trying to charge it, it is impossible to see if the battery has charged enough without the screen or a higher level charger that I don’t have. When it could be read for one to two seconds at a time, it kept giving me the wrong power level and ruined my battery. Now, I will need to buy a new one to avoid damaging another battery.

Pretty versatile for all 12 volt applications I use this while camping with a small lawn mower battery that I had laying around it also charges well with a solar charging system I use low volt lights and just recharge phones but I've also used it to charge a laptop works very well and will turbo charge your Android phone

This battery box was not well thought out.1) Battery boxes are often used as automotive jumpers. EVERYTHING on this one goes through a 30 amp fuse, including the posts and 50a anderson plugs. I will have to rewire it.2) USB-C plugs are NOT PD. What's the point of a 5v 2a USB-C plug3) Too expensive given the above limitations. I would have MUCH preferred a basic battery box with 2 unfused poles and 2 12v plugs with each having a 15a fuse for less than $40On the plus side, one can fit 80ah to 100ah of LiFePo4 cells in the box. but the use of high ah cells is "nerf'ed" by the low amperage circuitry. In fact, I would have much prefered just the two poles/terminals and flat surfaces that I could have used to install my own sockets, ports.

Great solution for 50 ah battery to connect to multiple products. Use the connection points to quickly run trolling motor and fish sonar on my boat. When not fishing I can quickly connect to our 12 volt fridge, air compressor or other 12 volt devices.

The battery-management system is really bad. It glitched soon after I bought it a year ago. The only way I can charge it is to connect directly to the batteriy posts. Ironically the two large connectors can be used to power 12v devices but the juice only flows in one direction.It’s an over-priced piece of Chinese junk.

I paired this the recommend battery and it all fit perfectly. Plenty of outlets, easy connections, on/off switch and volt meter. Great!
