Our take
A large box that can grow. It keeps a fridge, Wi-Fi and phones going for about 11 hours, and Anker says you can add one extra battery.

Estimates. Your devices may use more or less. One thing at a time, from a full box. We keep 85% of the watt-hours, because some power is lost on the way out.
What we think
The SOLIX C2000 Gen 2 is a large box. It holds 2,048 watt-hours. Watt-hours are how much power a box holds. It gives up to 2,400 watts. Watts are how fast something uses power. Its surge is 4,000 watts. Surge is a short burst some things need to start, like a pump motor.
What that means in an outage
By our math, counting a fridge at 120 watts, Wi-Fi at 15 and phones at 20:
- Fridge, Wi-Fi and phones: about 11 hours. That is about one night.
- Fridge alone: about 15 hours.
- CPAP: about 44 hours, by our math, for a CPAP that uses about 40 watts with the humidifier off or low. Check the watts on your own machine.
- A space heater that uses 1,500 watts: about 1.2 hours.
These are estimates. Your devices may use more or less.
Why this one and not the Jackery Explorer 2000 v2
The reason is room to grow. Anker says this box takes one extra battery, for 4,096 watt-hours in all. Jackery says the Explorer 2000 v2 is not expandable. This box also gives 2,400 watts against 2,200, and takes 800 watts from solar panels against 400. The Jackery is a bit easier to lift: 39.5 pounds against 41.7 here.
Moving it and charging it
41.7 pounds is about five gallons of water. Anker says it fills from the wall in 88 minutes.
The limit
Anker also lists a mode called SurgePad for up to 3,000 watts. That is a boost mode, not surge.
What we could not settle: Anker's own pages do not agree on a few lines. One page says the battery lasts 4,000 full charges and another says 3,000 or more. We list the lower one. They also give two sizes and two weights for the box. We list the larger of each.
Bottom line: a large box for one night of fridge and Wi-Fi that can hold twice as much later.
Good for
Outages that last through the night, and people who may want to add a second battery later.
Not for
Anyone who has to carry it up stairs often. It weighs 41.7 lb.
