Can a T25 run an alternator charger?
Posted: 28 Aug 2025, 11:34
Hi all,
I currently run my T25's power (lights/fridge etc) through a bluetti power station (AC180) as it saved the hassle and space of a leisure battery/inverter/solar controller plus I already had it from a previous self-build.
In the summer, it has been great as I have solar on the roof however, I am keen to use the van over winter and concerned the lack of sun will be an issue with my preference of being off-grid.
I have seen Bluetti now sell these: https://bluettipower.co.uk/products/cha ... or-charger which seem ideal as I would drive enough per day to keep the power station's charge up.
However, my concern is whether or not my van's alternator would handle the power draw? I have a 1981 2.0 Air Cooled CU with what I would imagine is the original (or similar replacement) alternator...
Bluetti FAQ say: "Charger 1 can be used with any vehicle with a 12V or 24V starter battery, including RVs, vans, and trucks" but google AI seems to think an alternator of 150+ amps would be needed.
Thoughts or has anyone done something similar?
(Thanks in advance for any advice
)
