Ratings & Reviews+

Wagan Tech EX 400W Power Dome Portable Power Source is rated 3.6 out of 5 by 78.
Rated 1 out of 5 by from dont be mislead !! This is NOT a generator, it does not create power, it is a battery only and has to be recharged at an electrical outlet or 12v source. The name GENERATOR should not even be used with this device...

Rated 1 out of 5 by from Power did not last long Plugged in and charged for 36 hours on a Wednesday-Thursday. Took it camping on Friday. Blew up my air mattress (5-10 minutes), went to bed about 1130 turned on my CPAP machine and plugged in a cell phone battery for charging, at 0200 woke up because me CPAP was no longer running...out of power. 2 1/2 to 3 of battery is not going to work.

Rated 1 out of 5 by from Wagan Power Dome I bought this item to use as a back up on my boat. I only used it once on a friends car and it would not start the car. After one year it would not take a charge.
