Using CTEK with jump pack?
Discussion
Unfortunately my garage doesn't have power (it's a rented lockup) and I'm going to be away for a while. I have a CTEK MXS 5.0 and was wondering - is it possible to connect it to a jump pack with a 3 pin input? Something like this Streetwize SWPP5.
And if that's feasible, does anyone have recommendations for a decent jump pack?

Errr....
Either remove battery and attach to conditioner somewhere that has permanent power or use jump pack the way it's meant to be used ? the jump pack almost certainly won't have enough power to "condition" a battery for a prolonged period.
P.S. - why use the jump pack to power the CTEK anyway - couldn't you just attach it directly to the battery to keep it topped up and avoid the parasitic losses involved ?

I used a CTEK 0.8XS with a Ring RPP265 powerpack and inverter. Worked fine when trickle charging and floating charge.
Have subsequently decided to do as suggested above and have removed battery and brought it home and float charge it from mains power as I will probably not use the car much at all this year.
Did the maths and worked out that fully charged Ring RPP265 would last around 25 days using a 0.8XS, although I decided to bring battery home after about 5 days, so never tested my maths.

My head hurts. You have a 12v battery in the car, and a 12v battery in the jump pack. You want to power an inverter from the jump pack to power a charger to keep the car battery topped up?
Just disconnect the earth lead on the battery. It won't just go flat magically, unless it's f'kd. Or take the battery out and keep it on the charger at home.

Yes disconnecting the battery or removing it and charging it at home would be the obvious solution. But then the alarm won't work and I've experienced an attempted break in to the garage recently so not sure I'd want to do that!
Also attaching the battery directly to the jump pack wouldn't be a good idea because of the risk of overcharging?

No. You have two 12v batteries in parallel. The voltage will drop in both equally.The jump-pack battery will be tiny, btw, compared to the car battery - it's basically just a small motorcycle battery in there. If you want to do something like that, get a big f'off diesel 4x4 battery and a pair of jumpleads. Cut one croc-clip off, and put a battery clamp on the other end. Connect it to the 4x4 battery. Bingo, instant monster jump box...
What you could do is now and again connect the jump pack directly to the car's connectors. Use the jump pack as the sole power for the car, while you take the car battery home to recondition it overnight. Swap back in the morning.
The car has still got its alarm active (and the sirens often have their own batteries anyway), you get the chance to look after the main battery, win win surely?
