How to Choose

Before you buy

01 · What's the highest-wattage thing you'll plug in?

Just laptop / phones (under 100W) → BESTEK 300W. Microwave, espresso, hair dryer (1000–1500W) → 1600W or 2000W pure sine. Air fryer or induction cooktop → 4000W.

02 · Are you OK hardwiring to the battery?

No (plug-and-play only) → BESTEK 300W is your option. Yes (or paying a mechanic $50–100) → any 1600W+ pick.

03 · Pure sine or modified sine?

CPAP, expensive electronics, or sensitive gear → pure sine, every time. Just charging phones and basic stuff → modified sine is fine and cheaper. When in doubt, buy pure sine — the price gap is small now.
