Frequently Asked Questions: Goal Zero Yeti PRO 4000 & Drip Coffee Maker

How long will a Goal Zero Yeti PRO 4000 run a coffee maker?

About 2.9 hours on AC power, with the coffee maker averaging 1,200 W (12-cup standard residential drip coffee maker brewing a full pot for 12–15 minutes (1,200 W)). The Goal Zero Yeti PRO 4000 then draws about 1,358 W from its battery, including 22 W for the inverter itself. Best case: about 3.9 hours (5-cup compact drip coffee maker (900 W heating element)). Worst case: about 2.5 hours (Commercial-style rapid thermal carafe coffee maker (1,400 W element)). At 0 hours a day, that's about 12 days.

How long does the Goal Zero Yeti PRO 4000 take to recharge?

On wall power: about 120 minutes to 80% and 150 minutes to full (Goal Zero figures). With its maximum 3,000 W of solar input connected, expect about 2,400 W in full sun, so a full recharge takes roughly 1.8 hours of full sun, so it can refill in a single day with 4 peak sun hours.
