AMP for GD77 missing from adapter

I want to calculate the wattage the stock AC adapter for the GD-77 draws at 120volts but Radioddity feels it irrelevant to list AMP?

Anyone know what it may be?

Not exactly.

I think the stock charger doesn't charge that fast. Probably only 500mA at 12V

So probably less than 10W allowing for inefficiencies
