ACOPOWER&LiONCooler 12V Portable Car Refrigerator-52 Quarts/50L,Battery/Solar Panal powered Fridge Freezer with App Control,-4°F-68°F Electric Compressor Cooler for Camping RV Truck and Boat

I have the 52qt in the back of my fj cruiser, currently just with a ratchet strap through the tie downs and to the front and rear fj tie downs and another across the front and it appears to hold in place solidly. I might remove the wheels to save an extra inch or so. But it fits next to the power outlet longways front to back and there is enough clearance in this configuration to open the fridge door.I spoke with Lynn from acopower who was very helpful and I collected a unit from the walnut California office. If anyone else is wondering they clarified you can safely leave power connected even when the battery is fully charged and the battery is turned on. That is important for me as I want to have the fridge connected to car power when driving and automatically be running off of battery when the engine is off/overnight. (The manual states it should be disconnected when battery is charged).I also have the 90w acopower solar panel which appears enough to run the fridge and charge the battery.The construction is somewhat plastiky; it’s clear all the money has gone into design, the li battery and the compressor which it appears upon inspection it is indeed a high quality lg unit.Setting the unit cold it will get from room temp to fridge temps super quickly, maybe 15-20 mins. As you move to freezer temps (down below freezing) the cooling rate slows as it works harder so definitely want to prechill it from ac/dc/solar rather than use the battery if possible.I don’t have a good overnight run time report from the battery yet as I’ve used it at high altitude at cold temps so it didn’t really need to work too hard.Acopower could probably have a solid overland/offfroad version if they added tie downs to both sides rather than just the rear and offered it in a squared off design without wheels so it could sit easily in a slide.For the price I think it’s great. If you are mainly using it for extended vehicle journey/overlanding you save the cost of buying another car leisure battery which you then need to find space for and also don’t need a dc/dc charger to keep that battery maintained from the alternator or main battery.Space-wise it fits a surprising amount. Mainly because all the space is available unlike a cooler where you add ice or ice packs. It’s profile is smaller than my 55qt lifetime cooler (great cooler) and appears to hold more as no ice.If it’s not clear from the instructions. You have to power the battery on with the button on the actual battery if you want that to be in an active state or to charge. The fridge will run from mains/dc without the battery inserted or with it inserted and turned off but it won’t change if not initially turned on.I have it in a big open space in the back of the fj. You probably would not want to run it in too much of an enclosed trunk space because of the heat kicked out from the vents as the compressor works.It could probably also do with a little extra insulation, once turned off the temp can climb quite quickly unlike a cooler. Maybe I’ll add another’s layer on top of the lid. But works fine when used as designed.The mobile app is ok (search for “portable freezer” in the App Store) and you can fiddle with the settings remotely with Bluetooth whilst driving which is good. It’s a bit flakey if the app is left open and then used again after a period - tends to just crash/close but opening it again is then fine. The first time you pair it (or it looks like afternoon removing battery) you have to reconfirm the pairing by pressing the cog icon on the fridge when it prompts in the app.I’ll update it after a few more months of use if anything interesting is learnt. But I think a good product so far that fills a specific need I had for ac/dc and battery power at the right price.

Purchased two of these cooler/freezer units without really doing my homework or research on them first.Both arrived promptly and well packaged with all the cables. I emailed ACOPower asking if I could fill and feed atthe same time (charge and use the battery), and Leo promptly responded to my question. The answer was yes, which is great! As my pic shows (more to follow), I wanted to test them out and "Pre-cool" them before last week's road trip to The Solvang area of California. One was hooked up to the "A.C." power (wall), non battery and on refrigerator temp 35F degrees. While the other cooler was set on "Battery" usage only, in freezer temp at 2F degrees.Started both coolers on "Max" mode to help cool them down faster and then switched them both to "Economy" mode when they both reached desired temp. Both worked great at home. During our road trip, I hooked up the Freezer cooler to our 12V van output and the Refrigerator cooler to one of our Goal Zero Yeti 500X as to not add tomuch on the vehicle's 12V system. Both ran well and kept the kids frozen treats frozen, while the other kept theOJ, milk, sodas, beer and wine cooled to perfection. No issues!At our first stop in Agoura Hills, the temp by the outdoor pool was about 98F degrees with a mild-warm breeze.The freezer ran on "Battery Only" (No input), for about 3 1/2 - 4 hours before I changed to the Fully charged spare battery, giving us a total of about 7+ hours of freezer mode service with nothing feeding the unit. At the same time keeping the frozen treats frozen in a warmer outdoor environment (tho in the shade). Truly impressive!Both coolers ran smoothly with no issues. I'm a big Yeti Cooler's fan and we still packed three of our soft coolers just in case there were any issues with these units and because I consume lot's of BudLight so needed more cooling space, but no issues to report!Will post more pics of these wonderful coolers of our trip very soon.Have to mention that we own two Alpicool 53Q cooler/freezers that almost look identical to these but with no battery service. Those run on AC/DC directly from another source (non-battery or direct solar hook-up). Meaning you'll need a generator/inverter, charge controller/battery charging system, etc., for those to run say while camping. Add an extra battery or two for the ACOPower coolers and you'd be in great shape in an emergency or a back country camping trip, charging the ACOPower Cooler/freezers and back-up batteries with solar panels directly. These units also have a light that turns on when you open the door/lid, which is convenient at night.I have not used the Wi-fi option as of yet but will update soon if/when I do. Hope this helps.
