I am interested in the Blue Smart AC-DC IP22 and IP65 chargers. I need to make sure I don't draw more than 15 amps in some scenarios. I believe the IP65 has 4A and 15A settings. Does the IP22 30A charger have a similar setting? Ideally, I would have 10A and full current options. I'm flexible on model, but need this low current functionality, and 10A as a low current option would be perfect combined with a full current (30A or more) option. Can anyone say if this exists in any model?
