The Safari ME outputs 2,000W and can power some AC units depending on the brand and the watts each AC unit requires. Like with most devices, the power consumption varies from brand to brand and model to model. So you'll need to determine if the AC unit is less than 2,000W. Check out our videos tab for a detailed review of the ME. Remember, if you connect the XP to the ME then you get an extra 2,048Wh of stored energy to power things longer.
