The maximum peak power is set at 14 watt which is 45W multiplied by 32% efficiency. Overriding power limits for AC power without battery: PL1 (15000, 18000) PL2 (41000, 41000) PL4 (14) BUG=b:364441688 BRANCH=None TEST=Able to successfully boot on jubilant SKU1 and SKU2 with AC only. Test on AC 65W and 45W w/o battery, and check PL4 values from log.
