Save 50% ($600 Off) the Anker SOLIX S2000 Power Station
The Anker SOLIX S2000 is one of the smallest and lightest 2kWh power stations I've seen, measuring 8.2" by 11.1" by 12.7" and weighing 36 pounds. It's 35% smaller than the C2000 and 6 pounds lighter. The S2000 is equipped with a hefty 2,048Wh battery array that's big enough to be your sole power source for off-grid use, or as emergency backup power for your home when you don't want to lug out the even heavier, noisier, and stinkier gas generator.
The S2000 has eight outputs, including five 1,500W (3,000 peak) 120V three-prong AC outlets, one 100W USB-C port, one 15W USB-C port, and one 12W USB-A port. It has smart functionality for remote monitoring and control via a mobile app.
The S2000 is one of the most efficient power stations available, with up to 96% inverter efficiency and a phantom power draw of less than 6W. That means your appliances will run even longer compared to other 2kWh power stations. The S2000 also functions as an excellent UPS battery backup with a switchover speed of under 10ms. Most other power stations labelled for UPS/EPS use have a switchover speed of under 20-30ms. That basically means your appliance, gaming PC, fish tank, CPAP machine, or whatever will carry on normally without interruption when the power source switches over during an outage, just like a typical dedicated UPS.
Speaking of the battery, the S2000 uses the latest generation 314Ah LiFePO4 battery cells that feature a 15-year lifespan and up to 10,000 charge cycles compared to the standard LiFePO4 battery cells with 10-year lifespan and 3,000 to 6,000 charge cycles. LiFePO4 has inherently safer chemistry, longer lifespan, and slower calendar aging than traditional lithium-ion. It is widely regarded as the best battery option for power stations.
Anker has another older 2kWh model - the C2000 - but the S2000 fills a different niche. The S2000 is also currently $300 cheaper than the C2000, making it a more attractive option for the budget-minded. The S2000 is also smaller, lighter, and more energy efficient. Tradeoffs include a lower power rating (1,500W vs 2,400W), a slightly slower maximum charging rate, and lack of a shore power outlet for RVs. TL;DR If you're not using the power station for super high power-demand needs like power tools or an RV, then the S2000 is probably the better choice for you, especially at its current lower price.
