Lithium ion batteries can overheat due to damage, overcharging, or exposure to high temperatures. In rare cases, this can lead to thermal runaway, a chain reaction caused by a rapid rise in temperature.
Our system is designed to reduce these risks by controlling how power banks are stored, charged, and used.
Every power bank is checked individually by hand before being installed into any machine.
Each machine displays a support phone number, and every power bank includes a QR code so issues can be reported immediately.
Our machines run on a 12 volt SELV system. This low voltage setup reduces heat build up and electrical risk.
Machines are built to operate outdoors and protect power banks from rain, moisture, and environmental exposure.
Power banks are charged only in our London facility, not inside the machines. Inside the machines, power banks remain dormant, with no power input or output, reducing the risk of overheating.
Each power bank is stored in a protective cardboard sleeve, adding separation and an extra layer of protection.
All power banks are cleaned after use to remove dirt and surface contamination between users.
Any power banks that fail inspection are removed from circulation and recycled responsibly with our recycling partner, Tes Amm, who recover materials such as cobalt.
All Lifesaver power banks comply with CE safety standards.
