How we assign awards →The differences that matter
- Continuous and peak output: 700 and 1200 W vs 1500 and 3000 W → the Ace 1500 runs far more demanding loads.
- Mains charging: 0.6 vs 0.9 kW; solar input 350 vs 400 W → the Ace 1500 accepts more power in both modes.
- Backup: UPS vs EPS, both in 20 ms → only the Handsfree 2 switches to battery without a gap.
- USB-C: 100 W vs 65 W → the Handsfree 2 charges a compatible laptop faster.

Choose Zendure Ace 1500 if…
you need to run loads above 700 W, up to 1500 W continuous and 3000 W peak, or connect up to 400 W of panels (against 350 W). It weighs 4 kg. You accept a brief gap in a blackout (EPS, 20 ms) and an IP31 rating.
