WANT TO BUY: (400 watt) Bluetti ac200 adapter/ charger

[Robbieburns0]

I want to buy a 400 watt ac200 adapter. I have a Bluetti eb240 and I am trying to accomplish faster charging rates. The older model (400 watt) ac200p charger works with the eb240 but they recently upgraded it from 400 watts to 500 and now it’s not EB240 compatible. Anyone willing to sell their old 400 watt adapter? You could upgrade to a 500 watt adapter ))

thanks
Robbie

Yes definitely. Just to be sure, you have a 400 watt adapter right? Not the newer 500 watt type?

i have an adaptor for the original AC200

How much do you want for it? And have you seen how much power it puts out? I am trying to use it with a 400 watt truck bed inverter with my Tacoma

 

[pigneguy]

i haven't seen how much power it puts out. $75

Can I please see the pictures, especially the label and the connector? Thanks.

this is what i have....

Well, it says here that the 500w adapter works with eb150/240 as well.

Thank you for your reply. That’s awesome that it’s compatible now. I ended up getting impatient and built my own variable voltage charger for my eb240. I used hobotech’s instructional video about it and it works great.

you're welcome, lol

I just had an interesting idea: if I connect my 2 200w eb240 chargers in parallel (I think they’re each 40v, 5a) with a 7909 2-female-to-1-male splitter, do I get 400w (40v 10a) output at the male end?

Answer is yes. See proof:

This is so awesome. Thanks for doing this experiment for power station science reasons haha. My question now is if the bluetti will take power from one AC charging brick and solar at the same time? That would solve a lot of issues for my truck camper setup / eb240. Thanks again!

I wouldn't do that since solar output voltage fluctuates a lot. MPPT controller is designed to regulate the fluctuation and search for the sweet spot (i.e. the Vmax).

So hooking solar together with power adapter will:
1. cause back feeding because of unequal voltage and
2. mess up the MPPT controller.
