Is this 20A x 2 or 20A total on AC? Companies tend to have an odd way to list that on multi-output chargers so it's not always clear. Thanks.
It will charge at 20A on both channels, but keep in mind it is still a max of 400W. This means that if you were charging 2 6S packs you'd get about 18A per side, anything smaller and you can get full power out of each side.
