We take a look at the top mobile batteries on the market to keep you connected all day on the field.


With the ever growing technical innovations in agriculture, staying connected in the field becomes more and more important, and making use of farm-management software on the go can become a challenge for our devices. Mobile devices in farming operations require a steadfast, reliable power backup that won’t leave us hanging when the battery starts to run low. That’s why more and more Croptracker users are turning to mobile batteries and power banks.

With that said, there are certain features to take into consideration when buying a mobile battery. What do you need out of a powerbank? In terms of capacity, the general rule is the bigger the better, until your battery becomes too heavy and cumbersome to carry around. A product designed to keep going for days may be quite large, as opposed to a smaller unit which may only provide a couple of charges on a cell-phone. The same is true of input and output ports. More ports will allow you to connect all of your equipment at once, but naturally this means a larger product. Related to this point is the type of port needed. Most portable battery packs have a standard micro USB port for input and a USB-A port for output. Others have a faster-charging USB-C port as well. Carefully consider what you’ll want to be charging on the go; if your battery doesn’t come with the right port, you may need an adaptor. Another key factor is charging speed. amperage, the amount of electricity flowing from the battery to the device, and voltage, the amount of potential energy, are multiplied to give you the total power or wattage. For charging speed, it is a combination of the voltage and the amperage that will determine your charge time.

Listed below are the ten best mobile batteries and power banks for the modern farmer. Note that for the most part, the words power bank, charger and battery are used interchangeably to mean the same thing.
