You keep it at home. Mostly, a car will fail to start in the morning. And not every car has a flat battery because the battery is faulty.
Mine gets used mostly for tyre inflation. And as an easily portable 12 volt supply.
When the battery died in my jump pack (no compressor), I cut the casing and put in a fiesta battery and added an inverter to the base. Now it will start anything and doubles as a mains source for drills, grinders, hedge trimmers etc. A jump pack is also very useful to keep a car alive while replacing its battery.
Even the smallest car battery is rather larger and heavier than the ones used in a pack like this. And I'm never far enough away from a power point at home to need a portable mains supply. ;-)
I find the compressor very useful. All the garages round here charge for air - and most seem to be broken when I want them too.
The original battery did not last many years and a replacement was as much as the whole pack! Yes, it is heavier, but it works far better than a standard cheap jump pack. The silent mains power is often handy if I go to the lock up and need power. I agree, a battery powered compressor is a very handy thing to have, and I have one that plugs into a cigarette lighter socket (should that be aux. power socket now?)
Quite. The whole reason I started this thread. You get a three year money back warranty - provided you keep the receipt.
Dave Plowman (News) spake thus:
That, and at home you're inflating them cold.
They're not going to warm up between here and the garage. ;-)
I though that was a cigar lighter socket... And I use a small footpump
