Captery is a spin-off of an experienced company (Rithema) with 160+ prototypes under its belt. Production is 90% internalized, reducing risk from external suppliers. Their Maker Faire presence and Jellop backing add serious credibility.
A sleek, modular design that combines the familiar shape of AA/AAA with future-ready tech. Recharges in just 160 seconds—seriously, less time than brewing coffee. Supercapacitor tech in standard battery sizes? That’s smart innovation done right.
Massive eco-upgrade: 500,000+ charge cycles, no toxic metals, and near-total recyclability. Reduces landfill waste from billions of single-use batteries. Safer, cooler, and greener—literally no downside for sustainability buffs.
Starter kits range from €10 (~$12) for accessories to €77–€299 (~$89–$345) for full kits. Fast-charging, ultra-durable batteries pay off over years of use. The €54 ULTRA Kit (about $63) is a great entry point for serious energy savers.
