good device weaken with each

We use the device only to jump-start, either for our own car or even surprising for by neighbors or friends. If the terminals are suitable (see below), it works quite well. the complicated maneuver with a second carriage is omitted, and you can also unassisted start his car again.

a small Quick Start Guide:
- Terminals of the battery with the "dead" cars combine, only red, then black
- Sure at least one minute or longer wait!
- All electrical equipment in your car and start attempt. if the car does not start immediately, power station a little longer be connected. ORGANS NOT!

the device itself is really difficult, probably because a fat lead battery sits in it. the various secondary functions we do not use as I said. the inverter function we tried for a cooler one, since the term was but quite short (less than one hour).

why only three stars?

1. the terminals do not fit to each battery (at our old golf 4 for example, is not). then you have hopefully a matching normal jumper cables on hand, with which you can extend,
2. the charging socket at the power station was after 3-4x invite worn so that the plug is no longer always get contact.

Another tip for last:
have lead-acid batteries to be recharged regularly (eg 1x per quarter), but should not permanently depend on the charger (I'd already due to possible gas development in the battery never do). then keep the problems for several years.
