I'm Lantern Parker and ride my BMW motorcycle in the winter, ice and snow is not as long. In the cold days I pack the Eufab 1 to 2 times a week theft in the saddlebags and connect this with the help of an adapter cable with the motorcycle outlet. The ignition does not need to be on during charging. I can remove during charging from Mopped including. If I'm making a charge for several weeks before the first start of the lead gel battery is fitt that even the ABS works. It is at the R1100R a typical problem that after a cold night, the battery is discharged to the extent that after starting the ABS does not turn on. By Eufab Qickstart but is enough juice in the battery to reliably turn on the ABS after 3 to 4 short trips. For tents of Eufab is also practical as electricity and light source. The included 220V charger is connected to the charging socket. This has the great advantage that the polarity can not be interchanged during the charging process. This has already happened to me with a comparable device. Since sufficient tenth of a second and the charging electronics goodbye with a small Rauchwölkche. That can not happen with the Eufab. Thus, the device complies with all around my needs.
