Most are 36/48 volt so car charger no use, must be the correct unit.We have a cheapo Aldi invertor to charge our Bosch powered bikes, but if you get a more expensive pure sine wave invertor you can charge things like tooth brushes which are inductive charge.
Also depending on model of bike you might be able to get a 'car' charger, which should be more efficient.
When I said 'car charger' that refers to a bike charger for use in a car.Most are 36/48 volt so car charger no use, must be the correct unit.
The car chargers I'm talking about are plugged direct into 12v and step up the voltage, no invertors involved and subsequently more effcient, at the time of my set up there where none available for our Bosch batteries, they where for a lot of other batteries, but IIRC someone on here pointed out they are about now for Bosch.Correct and he will need to know how many amps/watts it will use so as to buy the proper size inverter
Yes things change from week to week, just always have to keep an eye out, the cigy ones will be a very slow charge as the plug could not pull a big amperage.The car chargers I'm talking about are plugged direct into 12v and step up the voltage, no invertors involved and subsequently more effcient, at the time of my set up there where none available for our Bosch batteries, they where for a lot of other batteries, but IIRC someone on here pointed out they are about now for Bosch.
Most mains chargers are around 70w to 90w (e.g. 36v@2A), ciggy socket ones are pretty much the same.the cigy ones will be a very slow charge as the plug could not pull a big amperage.
What kind of Bosch batteries have you got? Probably different to mine (I have the 'Power for All" 12V type of batteries - https://amzn.to/2VoZT7Z ) and mosy of the kit came with a regular 240V AC charger - 13A plug and a large base to plug the battery into.The car chargers I'm talking about are plugged direct into 12v and step up the voltage, no invertors involved and subsequently more effcient, at the time of my set up there where none available for our Bosch batteries, they where for a lot of other batteries, but IIRC someone on here pointed out they are about now for Bosch.
I'm sure it was on this forum that someone posted a link to a UK website selling car to ebike chargers, might have been OAL. A quick google brings up several. My Bosch mains charger is totally different to your chargers, and it's only approx 85% efficient, add in an invertor and what does that drop too?
My experience of 12v to 20v chargers is that they are considerably more efficient than mains to 20v chargers, this might not apply to 36v chargers.
