I actually had a Buetti Adminctell me to sign up on their website and it was .com. have heard nothing yet. That would be sad if directed to use their site and result in scammers, will keep an eye open. Thx for heads up. I'm startingcto feel bad about my new bluetti purchase this week, with all my research I had only heard ostly good things about the build and customer service(other than supply chain ussues).It's strange, but that web address link you supplied is different than what I've been using. Everyone beware, the address https://maxoak.net/ is apparently a fake scam copy! The .net webste lists two different info@ conact email addresses. The .com goes nowhere and the .net is a scam that tries to get you to deposit money in a PayPal account.
Zilch,Those resin-potted heatsink style step-up convertors are available with several different specs, so you should be abke to find one that will suit your AC50S input requirements, if that's some thing you want to pursue.
Update on the 8mm adapters.Update.
I received my 1636.07 Lumberg 8mm 3 pole plug and a female plug. The odd thing about the male plug is that the inner shell does not seem to have a flange for the center pin to share the power. I may be out of luck using this if I can’t figure out how to get power soldered to bot my the center po and the inner shell. It looks like the inner shell is unpowered. I may have to figure out a kluge for it. Still testing the connections. Might have to solder a shiny from the center to the barrel as shown. With this custom adapter I may be able to use my 5 amp GZ adapter to car power the AC50s. My thought is that the OEM provided Bluetti cig to 8mm cable is not useful or sufficient to car charge the AC50s. That’s been my similar experience in other 12v battery charging.
if anyone has similar experiences or a fix please let me know.
Hi Seldomseen2u,On the Bluetti forum a guy using a AC30 that good success with a Lenovo 90W 20V PA-1900-53i charger. It has a 8mm plug and puts out 4.5A 20V. He said it works for the AC30. Anyone try this on a AC50S ? I maybe wrong but the input power port on the AC50S is 3 pole. It needs a hot center pin and the Lenovo does not provide center pin power.....
In his testing with the Lenovo, it seemed to show promise, esp. for the AC30. I recently obtained this Lenovo power supply and in testing with my meter I noticed that the center pin is not powered ? The inner shell is powered and the outer shell is powered. The AC50S MC4 to 8mm and the Cig lighter to 8mm all supply power to the input power jack. Does your Lenovo not supply power on the center pin or does your AC30 not require center pin power ?
When testing a iGreely 8mm jack cable it would not power the AC50S (unless i was testing incorrectly). I’d like to know what you think. I’m still under the impression that the Bluettis’ need 3 pole 8mm plugs to work correctly. thanks
Quick question for a newcomer. Should it be possible to wire 10G wire directly from positive/negative terminal of battery to power pole connector in bed of truck. Then go from powerpole to Bluetti with MC4 connectors as input for charging from car battery to Bluetti AC50s?
Hi,Hey y'all, I have what is probably a dummy question on the Bluetti. I just bought an AC200P, and am planning to rig it up in an old VW Vanagon for aux power (mainly to power a portable fridge/freezer). I want to get at least the trickle of a 12v charge from the van's cigarette lighter while I'm driving (portable solar panels while at camp). The 12v adapter works fine when plugged directly into the socket, but when I plug it into an extension, no dice! Double checked the extension with another device, no problems there. If I squeeze the connectors together super hard and twist it just right, it works, but won't keep working when I let it go. Clearly a poor connection - should I just try a different 12v extension cable? I ordered one on Amazon that I can return, so maybe that will do the trick?
Ideas welcome, thanks!
Oh and I love the idea of someday converting to charge faster from the van with some sort of up DC charger (if that's what it's called - I'm clearly a newbie at this!), so thanks for the above ideas!
Hi Harwood,Thanks zilch, really appreciate it. Not sure what's causing the issue, but I have another potential solution that I'd love someone to sound off on. Above in this thread the DC to AC inverter that runs off a cigarette lighter. This would have real advantages for the Bluetti - using a 12v cable to charge (if I could even get it to work on the extension) I would have to plug into the same port as the solar panels, thus I would have to switch out the cables every time I go to drive. Not a major problem, but with the location of the Bluetti in the van it's definitely a hassle factor. Going AC on the other hand completely eliminates this problem.
So here's the question - The Vanagon's cigarette lighter should be on a 15 amp circuit (also runs the radio and the clock). Do you think this DC to AC inverter will blow the Vanagon's fuse? You mention above that the cigarette lighter should be rated for at least 10 amps, so I should be beyond that. Just wondering if there's anything else I'm not thinking of? Also, any idea how much power it might actually supply? When plugged into shore power my Bluetti is drawing quite a bit through the AC charge port - currently shows 55 volts, 8.4 amps, and 466 watts. Curious how much it might get through this DC to AC inverter unit...
Thoughts appreciated, thank you so much!
