PiSFAU’s 200 W inverter has two US-standard AC outlets and four USB ports. The USB side shares 4.8 A, about 24 W, so four phones charge slowly together. It measures 2.7 × 1.4 × 5 in and weighs 8.5 oz.
Insulated shell
Instead of the aluminum used by FOVAL and BESTEK, the shell is fully insulated ABS. Protections cover overheating, under- and overvoltage, overload and short circuit.
Socket limits
At 200 W, it sits right at the limit of a socket fused at 15 A, about 180 W at 12 V. Expect the car’s fuse to decide if you load both outlets.

Questions owners ask about this one
Will four phones charge quickly?
The four USB ports share 4.8 A, about 24 W. With all four in use, each gets around 6 W, which is slow.
Can it run two devices on AC?
Yes, within 200 W combined and within what your car socket supplies.
Why ABS instead of metal?
PiSFAU says the fully insulated ABS shell improves electrical safety. A metal shell dissipates heat better.
Our score
8.0/ 10
A cheap way to add six outlets to a car. The USB ports share very little power, and 200 W is at the edge of what the socket gives.
