Aalso the start! I have 3 km to work and no electrical outlet in the garage (garage yard) I drive in the winter months at 2-8 degrees regularly the battery to the "clack-border". Nothing works anymore! As a shift worker, the car is also partially outside at night. The charged Apa start my car (Golf 1.6) loosely to the 15 times without complaint. At the border ichs not driven. Had a voltage tester at the Zig-lighter and the APA remains long on 12V. From experience I know that the start current starting at 11.8V at 0 degrees will be closely. This of course only with an intact technical condition of the car. Here it's all about power shortage. So I tell the APA is worth the money and who therefore does not fit his car doing something wrong or has other technical issues. I do not understand the whiners. Air pump I test when starting the bike season. Then there is an update here.
Update 24/03/15 Eben inflated mountain. Noise Level Normal for small compressor, faultless performance. Battery is still at about 13V charge. Great!
