The jump start I've used 2 times - and it was enough.
Once I had probably "empty played" my battery from the car through the cold and too much heater use.
She handed in any case not to start. So the Eufab connected (1x fully charged and for 6 weeks
in the trunk) and the engine started immediately.
The second time I have a colleague given booster whose car would not start before the company. Everything is OK
The compressor is enough to inflate bicycle tires. But is actually quite loud.
About the 12V output I have operated a lamp and a laptop. Enough for 2 hours.
Also at the voltage converter I connected the laptop. Also works.
One must not expect too much determined, but a manageable time can be the most diverse
Devices with power.
I can also imagine that, at Star Help trials of engines that would not immediately jump sowiso
the performance of Eufab may not be sufficient. In my experiments it was just easy on the empty vehicle battery, the engine is but otherwise jump immediately.
I just wonder how long the battery in Eufab holds the power, if you do not really invites him regularly and discharges.
