Nature's Generator Powerhouse Gen 2 review
Nature's Generator Powerhouse Gen 2 Whole Home Generator (4,800Wh, lead-acid)
By Tom Calder
4,800 Wh and 7,200 W at 120V and 240V, with an L14-30R outlet for a transfer switch or inlet box. It is lead-acid (AGM), not lithium: it weighs 434 lb, the store's support team puts its life at 500 to 800 full cycles, and the warranty is one year, against 3,000-plus cycles and about 135 lb for the 5 kWh lithium units here. For: a garage that stays put and wants 240V on a budget per watt-hour. Skip it if you'll move it, cycle it daily, or want a long warranty.
- Best for
- A plug-in 240V home backup unit, for buyers fine with lead-acid
- Skip it if
- You need to move it, use it every day, or want a lithium battery's lifespan
