Buying Guide

Battery chemistry matters

LiFePO4 (lithium-iron-phosphate) cells offer longer cycle life and greater thermal stability than standard lithium batteries, which is important for multi-year emergency readiness

Match capacity to your needs

Choose capacity based on what you need to run — small stations handle phones and lights while 1,000+ Wh units can power refrigerators or medical devices for hours

Check output ports and wattage

Ensure the unit has the AC, USB-C, and DC outputs and continuous and peak wattage ratings required for devices like sump pumps, CPAPs, or power tools

Prioritize portability and recharge options

Consider weight and integrated handles for transport, plus recharge flexibility such as solar input or AC charging for varied emergency scenarios

Evaluate warranty and cycle ratings

Look for manufacturers that publish cycle life and warranty terms so you know how long the unit should retain useful capacity in storage and use
