One more hopefully useful post.
Like many power stations, the Bluetti AC180 can be recharged from a 12 V vehicle power socket via its DC/PV input port. However, most limit charge current to ~10 A to avoid overloading the socket and its fuse.
The AC180’s input current limit is 8 A for DC voltages below ~30 V. Its battery energy spec is 1152 Wh, equivalent to a 12.8 V x 90 Ah battery. Assuming 90% charging efficiency, it could take up to ~13 hours to recharge the PS’s battery from a vehicle power socket (1152 Wh / (12 V x 8 A x 90%) = ~13 hrs.)
I no longer drive that long. 😴
I found a 120 Vac power brick with an output of 25 V nominal and up to 8 A via a DC7909 plug. This PB can operate from our truck’s cheesy built-in 120 Vac inverter (300 W) and should be able to complete a recharge in ~6.5 hours… perfect!
We should now be all set up for our next trip in October. 😎
Safe travels!
