I can run my computer and 55" TV with it just fine but realize it is modified and not perfect. RULE.. never plug the inverter into a generator to recharge your batteries since it requires sine wave and a generator is square wave. here is the web site:http://www.royalpower.com/p/3000-watt-transfer-switch-power-inverter-charger-12-volt-dc-to-110-volt-ac **Q: Has anybody sued them ?** A: I don't know if anyone has sued them but my son had got one, didn't work, got another didn't work, sent it back received another one and guess what?
