Question about Bluetti AC180P

Yes, in fact the device comes with a cable for charging via the cigarette lighter. But as the output power of the 12 V socket is only ~120 Watts, you need 10 hours for a full charge (from 0 to 100%). For accelerated recharging, it's better to use the 220 V from a household socket or to fit the vehicle with BLUETTI's Charger 1, which supplies ~500 Watts from the vehicle's alternator.

Yes, but only charges with around 60W

Hello Yes via the cigarette connection.

Yes, you can charge the Bluetti via the cigarette lighter. But this is more theoretical: I was only able to charge 2% of the Bluetti's capacity in 2 hours of driving. Do the maths! And when the car is not running, the voltage of the car battery is lower, so it probably doesn't charge at all.
Conclusion: After half a week without mains power, I had to drive to the village and recharge at a 220 V socket. That's quick.
One more thing: the Bluetti draws power for itself in idle mode, about 10 W by calculation. This is not stated anywhere, and is still a lot when the sun is not shining. I only realised this during practical operation.
The battery as such is great. Even the Nespresso coffee machine works, but then draws about 1 % of the battery power with every cup of coffee. Just to say.
