I bought the IEE SP5000 mainly for home backup, and it’s been rock solid so far. The 5120Wh capacity paired with the 5000W output is more than enough for our needs. During a recent outage, it ran the fridge, microwave, TVs, internet equipment, and even a space heater without any issues. I also like having both 120V and 240V available — it makes it way more flexible than smaller units. Charging speed is impressive too. Plugged into AC, it goes from near empty to full in about an hour and a half. Definitely feels like a serious whole-home backup solution. Read more

What really sold me on this power station is how fast it charges. With the 3500W AC input, it charges insanely fast compared to other units I’ve owned. I can top it off quickly before a storm or during short grid windows. The LiFePO4 battery gives me peace of mind — it feels safer, runs cool, and should last for years. We’ve had zero issues powering larger appliances, and the output stays stable even under heavy load. It’s heavy, but the performance easily makes up for that. Read more

I wasn’t sure how useful the app control would be at first, but it’s actually very handy. Being able to check input/output power and battery level from my phone makes managing usage much easier. The power station itself is quiet, stable, and handles high loads without stress. Between the large capacity, fast charging, LiFePO4 battery, and dual-voltage output, this feels like a long-term investment rather than a short-term backup. Very satisfied with the purchase.

We live in an area with frequent power interruptions, so the EPS feature was important to me. The automatic switchover is fast enough that our modem, router, and work computer stay on without dropping connection. That alone makes it worth it. The 5120Wh capacity lasts a long time, even with multiple devices running, and the 5000W output handles everything we’ve tried so far. Setup was straightforward, and the unit feels well-built and reliable. Read more
