Sakura 12v Power Inverter
This was the cheapest, least powerful and most compromised on test. Like the small Silverline, it will not be suitable for many cars, and it lacks a USB socket. We could hear no fan, so when overloaded it took a while before it could be used again. It did okay with most of our test gear, but the laptop defeated it – tripping the overload and putting itout of action for a few minutes.
