I bought a MotoMaster Eliminator Mobile Power Outlet Digital Power Inverter rated for 400 W.
It has thoses specs:
AC output voltage: 115 V
Max Continuous AC power: 320 W
AC Output frequency: 60 ±1 Hz
AC Output waveform wave: Modified Sine Wave
I can plug my little iPhone adapter in the inverter AC outlet and it charges.
When I plug my MacBook's adapter, I hear little ticks from the adapter, and nothing happens. I unplug it from the inverter, plug it in the wall outlet, and nothing happens. I have to unplug it from the wall, wait a minute or two, re-plug it to the wall and my MacBook is charging again.
What's happening? I bought this specially to charge my laptop when doing camping. Is there something I can do?
