Pila is the simplest, smartest backup solution for homeowners — and renters — to power what matters most during increasingly frequent, and disruptive power outages.
Each Pila battery stores 1.6 kWh of energy, expandable to 3.2 kWh with an expansion pack. This is sufficient to power essential appliances like refrigerators, charge phones, and run laptops for up to 2-3 days during an outage.
Pila Energy said the batteries will be available starting at $999 through early access reservations. The batteries are expected to ship by the end of the year and come with a five-year warranty.
The Pila Energy home battery is a portable, renter-friendly backup-power battery with enough energy storage to power a refrigerator for up to three days. The first plug-and-play, in-home battery for delivering automatic backup power throughout the home was unveiled at SXSW 2025 by Pila Energy.
On Tuesday, Pila announced it has raised $ 4 million to scale up manufacturing, via a seed funding round led by R7 Partners and joined by Toyota Ventures, Refactor Capital, GS Futures, and others. The startup aims to deliver its first batteries to customers in early 2026.
As outages grow and energy costs rise, Pila delivers affordable, modular backup power for renters, multifamily, and small businesses. Pila is the world's first plug-in modular home battery.
Mesh technology for whole-home power management: Pila is the first of its kind mesh battery. Like mesh Wi-Fi, multiple batteries work together through Pila’s Battery Mesh Network, quietly in the background, to store solar or utility power and optimize energy for outage protection and bill savings.
