AC trickle charge for Yeti 4000

is it possible to trickle charge the 4000 with the 120 watt Yeti X AC power supply? My 4000’s voltage and state of charge % seem out of sync. When I trickle charge off my vehicle alternator at 120 watts, the voltage seems to be closer to the state of charge. However, when I use the 4000’s AC input port or my 400 watt solar panel with the hpp+ port, the state of charge goes up to 100% relatively quickly, but the battery voltage indicates only about 70% charge.
