Connect Red power to the positive terminal of the battery
Black wire to a metal part (not to the battery)
Switch on the device with switch and wait a bit
Only then start the engine
If that does not work:
Check contacts
Unit really turned on?
Car battery might be defective?
Device is fully charged (can be read on the meter when the test button is pressed)
Not waited long enough?
(A total empty car battery pulls sucked at the beginning of a very high current, and charged by the battery of the starting system considerably, so that hardly any juice for the starter is left.)
Himself to a dead battery tasted (petrol vehicle) => unit has easily coped with several start-ups / event operations (take breaks between startups!)
The compressor is noisy, that's right. I see it but rather than treat, and also find it convenient times up his bicycle tire thus inflate again.
Only downside is the weight of the unit. But technology and particularly the battery (battery) weighs unfortunately ...
The short connecting cables were often criticized, but if you follow the instructions, the ground wire to a (unpainted !!) hanging metal part, this is no problem, since one is then a bit more flexible. One should take it but know that the site close to the engine (starter) is.
And to supplement: It was actually delivered 900 Ampere device. Only this has a 17Ah battery, the 600 amp device only a 7Ah battery. What you should know and Amazon has probably something mixed up here. The 900 A device was evaluated, this is also much more difficult.
