How to Choose the Best Small Battery Backup?

Battery-powered backups and solar generators can keep all the appliances running during a power outage, brownout, or blackout. However, all of them come in different sizes and capacities. For example, the lightweight solar generators are designed for outdoor activities like hiking and camping, whereas the larger ones are more geared towards the needs of homeowners.

If you want to select the best small battery backup for home, here are the factors you will need to keep in mind.


The total amount of power or energy any battery can store is called battery capacity. As a general rule of thumb, the larger the battery capacity, the higher the power output. If you want to charge small appliances like phones and tablets, then Jackery Explorer 300 Plus Portable Power Station would be a great choice. On the other hand, those looking to power multiple home appliances may consider a larger battery backup like Jackery Explorer 1000 Plus Portable Power Station.

Safe and Clean

Gas generators often emit a lot of noise and toxic fumes while working — and that's the reason they are not suitable for indoor usage. Solar generators and portable battery backups are safe and clean charging solutions. They do not emit any noise or toxic fumes while working — making them safe for indoor and outdoor purposes. The Jackery Explorer Portable Power Stations not only offer clean energy but also feature advanced battery management technology to promote safe charging.

Size and Weight

Small battery backups are generally used for outdoor purposes. For this reason, it is essential to keep the size and weight of the solar backup in mind. The Jackery Explorer 100 Plus Portable Power Station weighs only 965 grams and can be carried within the palm of your hand. The larger Jackery Explorer 1000 Plus Portable Power Station for the home has a foldable handle, making transportation easy.

Input/Output Ports

When deciding the best small battery backup for your home, you'll need to check the number of input and output ports. The higher the number of output ports, the more appliances can be charged simultaneously. The mini Jackery Explorer 100 Plus Portable Power Stations has around 99Wh and can charge up to 3 devices simultaneously. The larger battery backup models have a higher number of output ports to charge many appliances at the same time.


LiFePO4 typically has a longer lifespan than other battery types like lead acid or lithium-ion. The LiFePO4 battery in the Jackery Explorer 1000 Plus Portable Power Station can last up to 10 years and provide around 4000 charge cycles. Likewise, the other Jackery Explorer Portable Power Stations have a higher lifespan to ensure you can enjoy free solar power for years.
