Can the device - even 3-4 years after purchase, if fully charged - start a deeply discharged 2.5-3.0 litre diesel engine in winter? I am interested in this jump starter.
Unfortunately I couldn't find any independent tests / reviews, only info from Swaytronic and dealer sales pages. Feedback from Digitec/Galaxus customers suggests that the part works well with smaller car engines (and possibly relatively new equipment and/or in summer), but has failed with larger engines or in winter.
Many thanks at this point for any helpful answers.
Hoi - yes and no: I already used it to start our Land Rover (still a TD5) when it wouldn't start any more - I'd had the jump starter for 1 or 2 years at the time. If you charge the battery and store it appropriately (not super cold, not super hot) then the part should be able to start the engine for you - it just doesn't last too long. But: For example, with a deeply discharged battery and with a V6 Fiat Freemont 3.6: No result, it turned over but the engine wouldn't start (but the part also had electronics like a gogo and consumed enough of it). Only pre-charging with a battery charger helped...
