During the trip I had a laptop, tablet, and an extender with two DSLR camera batteries all pugged in at once, the BESTEK never had a problem. Very impressed by it’s durability and ability to power multiple devices simultaneously. Fan is a little noisy when car is idle but you it exceeds standard road noise.
