Re: portable fridge and 12v socket

Re: portable fridge and 12v socket

It's actually a Lithium-ion battery. You can use it a lot more than one time.

True, but like any other battery, they are subject to slow leakage. The trick is to ensure that full charge is maintained. many just throw the pack in their toolbox and forget about it until required. At that point they find that due to leakage, the battery has inadequate grunt to turn the motor over.

Re: portable fridge and 12v socket

I just wanted to clarify that it's not like a capacitor in any sense. You can crank over a motor repeatedly even when the vehicles battery is totally drained. It behaves just like the old style jumper box, but without the weight or large physical size. It also holds a charge unused for a long period of time even left in a cold vehicle. Lithium Ion technology is the shizzle.

Re: portable fridge and 12v socket

I have a van with 2 x 120Ah Lithium batteries. I can assure you, they drain.

Re: portable fridge and 12v socket

What battery doesn't and who ever said they don't? I'd sure rather have a small jumper box than nothing. If I have to charge it once or twice a year big deal. We all understand they drain. Geesh.

Re: portable fridge and 12v socket

AGM batteries (as fitted to WK2's) are inherently deep cycle batteries and the Jeep battery works fine running fridge overnight. As said before though. Have a backup plan.

Re: portable fridge and 12v socket

That should be as long as it's not a 3way fridge.

Re: portable fridge and 12v socket

Think you will find they are lithium with a capictor to up the cranking power in one hit

Re: portable fridge and 12v socket

just as a followup. tested the rear 12v socket only managed to get about 58watts from it so a little less than the front 2 12v sockets that managed 65watts.

if the arkpak can charge at 7amps dc theoretically that would equal 12x7 = 84 watts which I'm not seeing out of 12v socket.

bought a car battery charger to top up the arkpak at powered sites now

Drop My lithium ion drill batteries all the time and have lived to tell about it. Also my son is hardcore into RC hobbies, short course, crawlers, planes, boats. All utilize lithium ion batteries. I don't have too many worries about them. My sons RC batteries do get charged inside a safety sack though. They even make full sized car that use them.
