XT60 cigarette plug hot

Product Discussion
1

I ordered an XT60 cable/ cigarette plug from Amazon. 6 1/2 feet long, 14awg in July. I have a dedicated/fused cigarette female plug receptacle and after about two hours the plug part gets incredibly hot on the metal parts when charging my Elite 100 V2. After I ordered it, I got the Elite 10 with a XT60 cable, 16awg 3 foot plug. Should I ditch the 6 1/2 foot plug from Amazon and stick to the standard Bluetti Issued XT60 that came with that unit and use it with the all my XT60 Bluetti’s?

Thanks

Quality of Cig Plugs and the cables soldered to them cover a wide variety, many of which are dubious. Not only the plug itself, but the cable and the soldering.

The factor most people do not know, particularly with vehicle sockets is; I’ll use my Toyota 4x4 as an example. There is a front row centre console socket and a 2nd row rear centre console socket. They are on the same circuit rated 12VDC at 10A. This is a conbined load, not each.

Another point - I run a 40lt Engel fridge/freezer combi from an auxiliary rear bootspace battery. The Engel comes with a 12VDC lead fitted with a cig plug and I initially tested it from a cig socket. The plug was hot enough to be “too hot to the touch” and the load was 3.1 amps or around 38W. (Much less than the 100W a Bluetti draws) My first job, buy a spare Engel 12V lead, cut off the cig plug and replace with a 50A Anderson plug. It’s much safer and a more positve connection, especially on rough tracks. The only device I use in my 4x4 with a cig plug is a Hema Navigator GPS as it’s load is mA. (The original Engel cable was kept as is, for warranty purposes)

BTW - for extending 12V Bluetti charging cables, I’ve made up a 5M (15’) Anderson to Anderson with 6mm sq cable (10AWG), then a smaller cable Anderson to XT60, also 6mm cable. It handles the load no problem and very little voltage drop. (Both of these cables are commercially available) In fact, I also have a 10M (30’) Anderson extension as I also have a tyre compressor powered from the start battery and tow a caravan (RV Trailer).

So ditch the longer cable?
