Left AC200MAX charging and it melted the plug

Left my AC200MAX charging over night, when I checked the unit the next morning the plug from the AC adapter had melted in the unit. Reached out to support to see if this is covered under warranty, still haven’t heard back from them.

Hi @gmen50 , Based on this situation, you need to contact support to return the machine and adapter. Also check the machine and adapter barcode (SN code) and inform the support department of the usage conditions

Assuming the unit was charging normally, I would think the plug and socket were not fitting tightly or not fully plugged in. This can cause resistance which will heat up connections. Could be an undersize plug on the adapter brick.

Right, this company support is the worse. Sent an email no response. You call, mailbox is full.

Hi @gmen50 , sorry for inconvenience caused. Support will respond to your emails, but the mailbox have been overloaded lately. The response time may not be timely. What is the email address you used to send your letter to our support department? And your order number. We will use this information to check with support to prioritize your issue.

Had this same condition but did not melt completely. Using this type of plug for that high of watts is not the best option. The plug would not make good contact and would heat up but not to the extent of your unit. Did contact the company and they did replace the entire unit but it did take some time as I had to send the original unit back before they sent a new unit out but it did finally work out.

I sent my unit in and have emaied over and over to get a status update. To date i have not recieved a call or email from support .

Truly regret spending all this cash on this product. Support is so freaking bad.

Hi @gmen50 , can you please send me your order number or your email address ? So that I can check with support for you and have it processed for you as soon as possible.

I have this same problem. Used the AC200MAX daily with grid charging over a month and then the barrel plug melted. No response from email to service@bluettipower.com. Sent email 9 days and 3 days ago.

Same issued here! Plug and/or socket are inappropriate for the load. Bad construction. In my case you can see in the picture below that plug internal yellow/white plastic material was streaming out due to the heat of the physically inappropriate connectivity.
@buetti: please look for a workaround!

another remark: checked after one hour of grid loading at ~390W (this is what the display shows) also the complete cable from the grid adapter to the plug becomes warm in a room with 18°Celsius.

I still havent gotten a reply on my unit. Mine melted aswell. And would like a full refund.

Are you using the fanless t400 charger or the (with fan) t500? I’ve rarely used the grid and barrel charger on my ac200max, but with the t500 I see 450 - 475 watt charging input and no overheating issues.

On a side note, a while back I use to charge my eb70s with solar using the same 8mm barrel plug. When I had 2X 200 watt pv’s connected to it in parallel, I noticed it would get pretty hot to the touch. I had a small fan that I would aim at it. That kept the connection cool.
