Smartphones have been revolutionary but battery life continues to be an issue -- but this keychain charger is just the solution to have in a tight squeeze.
The 'Emergency Keychain Charger' by Pulsepak is for when you're in need of a quick charge without any additional bulk to carry around. People resort to all sorts of measures to stay connected: carrying a charging wire, charger cases or other charger devices, but this keychain charger is a tiny battery pack that fits on your keyring without sacrificing functionality.
The charger is roughly around the same size as the rest of your keys and can provide up to two hours of additional use. It has a retractable micro-USB or lightning connector, so there is no need for a charger cable.
