What the cigarette socket can really deliver · review
A 400 W car inverter with an 800 W peak, two AC sockets, two USB ports and a 30 in cord, with a fan that starts at 113 °F, for $34.98.
Pro Chaser’s 400 W inverter comes with a 30 in cord, the longest here, so it can sit where it gets air. Its fan starts at 113 °F. Two 110 V AC sockets and two 3.1 A USB ports, 4.8 A together, complete it. A safety notice in the listing tells users to keep it cool and dry and to treat its output like a household outlet.
The inverter is rated 400 W continuous and 800 W peak. As with BESTEK’s 400 W model, a cigarette socket fused at 15 or 20 A limits real output to roughly 180 to 240 W at 12 V.
Pro Chaser listed it at $34.98 on November 2, 2026, with a 12-month warranty.

So the inverter can sit away from the socket, in the open where its fan can cool it, or within reach of the back seat.
Pro Chaser says the AC outlets handle 300 to 400 W devices. Through a cigarette socket fused at 15 or 20 A, about 180 to 240 W is realistic.
Pro Chaser warns to use it in a cool, dry place and to handle it with the same caution as a wall outlet.
8.1/ 10
A 400 W car inverter with a long cord and a candid safety note. The socket, not the inverter, sets how much of that 400 W you get.
Same category, nearby prices, between portable power units. What remains is the specifications every one publishes — half empty, a column is no use.
