Purchased a oxygen machine which has a DC adaptor and connects to the accessory outlet which is fused at 20A. The adaptor keeps blowing it’s fuse (10A) and the black box is extremely hot. Vendor says the car has a limiter in both the cigar outlets which causes the problem. Buick dealer provided a schematic of both circuits which shows no limiters and tells me the problem is the adaptor is insufficient to handle the electric requirements of the machine. Don’t know where to turn next. Any help would be appreciated.
buy a power invertor and use the ac adapter.
