The BLUETTI D40 is a DC-DC battery charger that connects an AC200L power station to an RV's 12V house battery. It outputs 12V at 30A, 400W max, and Bluetti lists it as compatible with LiFePO4, AGM, gel, lead-acid and calcium batteries, so it covers the batteries fitted to most travel trailers and campers.

The practical use is charging the house battery from the AC200L, from solar panels or from the tow vehicle's starter battery, and running 12V RV appliances from that supply. Bluetti describes it as plug-and-play for the AC200L with house and starter battery protection built in. It is only listed for the AC200L, so check your station model before ordering.

  • Compatible station: BLUETTI AC200L
  • DC output: 12V / 30A, 400W max

  • Charge sources: AC200L, solar panels, starter battery

What it fits

  • Fits: Bluetti lists the D40 for the AC200L power station only, so check the model badge on your station before ordering.

Messed with a good thing and it now sucks!

Not happy with this product at all! I never leave reviews, but wanted to let others know about this D40. I have had two of them and neither works as it should. I constantly get errors, or go out and the fridge that is normally running off my batteries and it is dead because of error messages kept the battery from charging. BLUETTI has been zero help, which is on par with the experiences Ive had with their support in the past. Don’t understand why they removed the 30amp 12v outlet on their devices. I guess for us to purchase another useless item.

Forgot to mention in my other review

Forgot to mention in my other review that the charging from the main vehicle battery has never worked and that is on two separate D40s. Buyers beware!

Perfect!

The D40 does exactly what it says without fault. Keeps my house batteries topped off from my AC200L/B300K(x2) without me worrying about it.

Bluetti D40 DC DC

Thank you for a very good solution to using the 48v/8a port as a Fuze box junction. This has allowed dc volts to power my entire truck camper.

Works as advertised, but the cable is not as long as shown in the pictures. The real length is about 4 inches
