Where the points went

The Solar Score weighs performance, build, value, safety and warranty. For a generator, safety means pure sine wave output, a CO sensor and a LiFePO4 battery, and fuel generators run outdoors only, far from doors and windows, because of carbon monoxide. Warranty terms stated here are 5 years for the Anker and 2 Year Manufacturer for the maXpeedingrods. How we pick explains the weights.

Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.

How to choose the best generator for well pump

Starting watts and running watts

A well pump draws a surge when it starts, then settles to its running draw. Compare starting watts: the maXpeedingrods states 5000 peak watts and 4000 running watts, the Anker states 3,000W peak output and 1,500W continuous output, and the WEN states 5600 watts. The Generac states no watts, so its starting watts cannot be compared. A generator that covers the starting surge and the running draw is the pick for a well pump. A pump that needs more starting watts than the Anker 3,000W peak output needs the fuel generator instead. The benefits of an inverter generator are covered in benefits of inverter generator.

Power station or fuel generator

The Anker is a power station: a 2,010Wh LiFePO4 battery with 1,500W continuous output, 8 outlets and up to 400W solar input, and it recharges from a wall outlet, a generator, solar panels, an alternator charger or a car outlet. The Anker measures 8.2 by 11.1 by 12.7 in and weighs 35.7 lbs. The maXpeedingrods is a fuel generator: 5000 peak watts and 4000 running watts on gasoline, with an ECO mode that adjusts fuel use. A power station needs no fuel and recharges from solar, while a fuel generator covers higher watts. Pick the station for short outages and solar recharging, and the fuel generator for higher starting watts.

Capacity and run time

Capacity decides how long a pump runs: the Anker holds 2,010Wh and runs a fridge for 35 hours, with 6W idle power draw. The maXpeedingrods states no run time and no fuel tank size, so its run time cannot be compared. The Oxseryn options after the picks state run times: 14 hours at 25% load for the 4400-watt model and 9 hours at 25% load for the 2800-watt model. Match the capacity and run time to the pump and the outage length you expect. For backup power at home, see the best portable power station for camping.

Outlets and ports

Count the outlets before choosing: the Anker has 8 outlets, front and rear, and no 12V DC port. The maXpeedingrods states no outlet count, and the Oxseryn 4400-watt model has 2 120V AC ports, 1 12V DC port and 1 RV port. The Oxseryn 2800-watt model has 2 120V AC ports, 1 12V DC port, 1 USB port and 1 Type-C port. A well pump needs the right outlet for its plug, so check the pump plug against the outlets stated.

Fuel, solar and recharging

The Anker recharges 6 ways: AC plus solar, a wall outlet, a generator, solar panels, an alternator charger or a car outlet, with up to 400W solar input. The maXpeedingrods runs on gasoline with an ECO mode that adjusts fuel use. The Oxseryn options after the picks run on gas too: the 4400-watt model has a 2 gallon fuel tank and the 2800-watt model has a 1.1 gallon fuel tank. Match the fuel or recharge source to the outage: solar for a station, gasoline for a fuel generator.

Sizing Notes

• Match the starting watts: the maXpeedingrods states 5000 peak watts, the Anker states 3,000W peak output and the WEN states 5600 watts.
• Match the running watts: the maXpeedingrods states 4000 running watts and the Anker states 1,500W continuous output.
• Match the capacity: the Anker holds 2,010Wh with up to 400W solar input; the fuel generator states no capacity figure.
• Match the outlets: the Anker has 8 outlets and no 12V DC port, so check the pump plug against the outlets stated.
• Match the warranty: the Anker carries a 5 years warranty and the maXpeedingrods carries a 2 Year Manufacturer warranty.

FAQ: power away from the grid

What size generator do I need for a well pump?

Compare starting watts: the maXpeedingrods states 5000 peak watts and 4000 running watts, the Anker states 3,000W peak output and 1,500W continuous output, and the WEN states 5600 watts. A generator that covers the pump starting surge and running draw is the pick.

Can a portable power station run a well pump?

A power station can run a pump when its output covers the starting surge: the Anker states 1,500W continuous output and 3,000W peak output from a 2,010Wh battery. Check the pump starting watts against those figures before choosing.

Can I recharge a power station with solar panels?

The Anker supports up to 400W solar input and comes with a 400W panel, and it also recharges from a wall outlet, a generator, solar panels, an alternator charger or a car outlet.

How long will a power station run a fridge?

The Anker runs a fridge for 35 hours, with 6W idle power draw and 10% higher efficiency than other 2kWh systems.

What is ECO mode on a generator?

ECO mode lets the motor adjust fuel use: the maXpeedingrods states its eco-mode adjusts fuel consumption to prevent unnecessary gasoline usage, and the Oxseryn models state ECO mode with run times of 14 hours and 9 hours at 25% load.
