I’d give it 0 stars if I could. Bought this EXPENSIVE power pack and used it twice before the cord that connects the OCI to the fridge went missing (my fault, I know). Been trying to buy a replacement cord for MONTHS now with no joy. No stores have them in stock and even MyCoolman website doesn’t have the cord. Contacted MyCoolman customer service 2 times and all I get is an apology and an excuse that they have manufacturing issues with the replacement cord and no ETA.
There you go - buy yourself this expensive gear and when you need to replace a 25 dollars cord you can’t u less you “McGyver” something up.

Although I haven’t been on the road with myCoolman lithium power pack yet I have charged and run it once in my work shed on a 33 degree day. I was amazed how effective it was on this one use with my 44 litre fridge. I just checked it this morning and it has been running on 2 degrees for 21 hours now and there is still one blue charge light showing. If it continues to be this effective and the beer stays this cold on our travels I will be one very Happy Camper!

I have run the fridge for 3 days at -15c & 4c in my garage at max 25c air temp with each compartment at 90% full. It has run flawlessly. However I trialed the battery and 100% charge it lasts only 6hrs 15min so not quiet a full night which is a pity as 12hrs would have been great. Luckily as the insulation is so good non of my food is defrosted. MyCoolman should consider offering a bigger battery for the larger fridges. The DCDC Charger is a great accessory.

Great concept, great product and it worked really well for almost 8 hours, however it wouldn’t charge after a single use. Wasn’t ideal as the fridge could only be powered whilst the vehicle was operating so the trip was cut short.

Would buy again and hopefully the next one lasts longer. Not faulting the product in general as it’s great and I’m sure it’s not a common issue.
