## Input Watts for Blue Smart IP65

Can you tell me the watts used by the Blue Smart IP65 chargers in both normal and reduced modes?

Looking at the 7, 10 or 15A models.

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

The consumed power at the AC input could be calculate like so:
Battery Voltage x Battery Charge Current x Efficiency Factor

So for a 10A charge current and the battery nearly full at 14.8V and an efficiency or 94%

10x14.8x1.06 = 157W

You can use that formula to calculate the power consumption for other charge currents as you wish.

I have the IP65 12/15 120VAC model (that I use to charge a 400Ah set of lithiums in parallel) and recently plugged the IP65 into a "kill-o-watt" meter. When pushing the full 15A using the lithium protocol on batteries that were 35%SOC, the charger was using 230W. VoltAmps were 238VA, and current draw was 2.42A.
