What is a Watchdog Battery Backup?

Basements are more prone to flooding. When the water trickles in, there's no place to go. That's why basements have sump pumps installed in a pit. However, storms that cause flash flooding and high winds also cut down the power line — leaving your home without electricity for days.

Watchdog battery backup for sump pumps automatically start pumping during blackouts or power outages when the main sump pump fails or when water flow exceeds the capacity of the main pump. For those times when the sump pump fails, it's a good idea to have a backup plan like Jackery Explorer Portable Power Stations.

These lightweight and compact batteries charge sump pumps and other appliances, like ACs, heaters, and refrigerators. Simply connect the sump pumps in the output port of the Jackery Explorer Portable Power Stations and start powering the appliance whenever you experience power outages.

Why Do You Need a Battery Backup for Watchdog Sump Pumps?

If you live in an area that's close to the floodplain or have a high water table, you'll have a sump pump installed. Here are a few reasons why you should invest in battery backup for sump pumps.

  • A battery backup will not only power the sump pump but also other appliances that might need continuous power.
  • It ensures the sump pump never stops and helps protect homes from water damage.
  • If the power goes out or the circuit breaker trips, the backup battery will continue to operate efficiently.

How Does Battery Backup for Watchdog Sump Pumps Work?

The watchdog battery backup for sump pump is a two-stage system. The sump pump uses the home's power when electricity is available — and when there is a power cut, the battery backup starts functioning by supplying electricity to the sump pump. Jackery Explorer Portable Power Stations can charge small to large appliances like sump pumps.

The Jackery SolarSaga Solar Panels are made with monocrystalline silicon solar cells and can convert free solar energy into DC electricity. The Jackery Explorer Portable Power Stations feature a pure sine wave inverter to quickly convert the DC to AC electricity, which can then be supplied to electrical appliances like sump pumps.

How to Choose the Best Watchdog Battery Backup For Sump Pumps?

Battery backups for sump pumps require a high upfront cost — and hence, it is essential to choose the best watchdog battery backup. If you want to keep the basement free from water damage, here are the factors to remember.


Battery capacity refers to how much energy or power the battery can store or deliver to the connected appliances. This means that if the battery capacity is higher, it can supply electricity for long hours. The best way to pick the proper battery backup is by calculating the sump pump wattage. Always make sure the battery has enough capacity to supply electricity for at least a few hours in case any power outage occurs.


Next, the size of the battery backup is an essential factor to keep in mind. You'll want to consider a watchdog battery backup for a sump pump that's easy to move from one place to another. It should at least have wheels and a handle for moving the power station and charging appliances. Generally speaking, Jackery Explorer Portable Power Stations is lighter compared to other battery backups with the same capacity. A portable sump pump battery backup ensures you can even charge outdoor appliances whenever needed.


Unlike gas generators, solar battery backups do not emit any toxic fumes or noise. Consider looking for a battery backup that operates with only 30-45dB, which resembles the refrigerator's hum. Most of the large Jackery Explorer Portable Power Stations emit only 30dB of noise when operating.

Input/Output Ports

The number of outlets represents how many appliances can be charged simultaneously with the battery backup. If you want to charge multiple electrical devices along with sump pumps, you may consider Jackery Explorer Portable Power Stations. For example, the Jackery Explorer 3000 Pro Portable Power Station features 4*AC, 2*USB-C, and 1*carport output ports to charge 7 appliances simultaneously.

Long Battery Life

The sump pump battery backup should have a long battery life, reducing frequent repair and replacement costs. Jackery Explorer Portable Power Stations have LiFePO4 and NMC batteries that are long-lasting for up to 10 years.
