Buying Guide
What power capacity do you need? Start with your essential devices and add up their running watts to estimate needed capacity and peak draw. Consider LiFePO4 chemistry for longer life and safer charging in indoor environments. If you want flexibility, choose expandable systems like the Delta Pro that can grow with your needs. Noise level matters for indoor use; look for units designed for quiet operation with sound-dampening enclosures or smaller form factors.
What should you avoid for indoor use? Gas-powered generators produce fumes and require ventilation; they are generally unsuitable for enclosed spaces without outdoor placement and proper exhaust management. Electrical safety features such as surge protection, UPS mode, and overcurrent protection are important for protecting sensitive devices and preserving battery health.
Portability vs. capacity: small units (under 1000Wh) are easy to move but power fewer devices for shorter durations. Mid-range units (1000–2000Wh) balance portability and run-time for most homes. Large units (over 2000Wh) power more devices during longer outages but require more storage space and power planning.
Compatibility and expansion: if you foresee longer outages or future upgrades, consider systems that support additional batteries or expandable configurations. Check for multiple output options, including USB-C PD for fast charging of laptops and phones, as well as standard AC outlets for household appliances.
