Hi All,
I recently purchased an Arkpak as a portable camping solution. One of the main uses will be to power my CPAP machine at night so a duel battery system stuck to the car wasn't going to be as handy. I also have a 120w solar which I will use to keep the battery topped up at
camp. I set it up on the weekend but found that the MPPT seems to have gone a bit dodgy - the digital read out wan't working correctly. So I may be up for a replacement.
I haven't bought the Arkpak DC-DC charger as yet, as most of my upcoming trips don't really need it however if I was thinking perhaps a CTEK 250 Duel may be a better option anyway. It has a higher charge rate at 20amps than the 6amps provided by the Arkpak and can also act as an MPPT for the solar.
Has anyone with a portbable battery setup, like the Arkpak, gone down this road and are you happy with the results?

Here is a silly follow up question.
Can the Ctek be connected using the Cig Socket in the rear cargo area?
I believe the Arkpak DC charger can but it is only running 6 amps as opposed to the 20amps on CTEK 250 duel puts out.
The car is a 2011 WK2 Jeep Grand Cherokee. I only have 12 months left on a novated lease so would prefer not to spend money on a solution that ends up permanently fixed. Something that I can easily remove and take to the next car (whatever that is) would be preferred.
