Duracell SafeJump

Advanced Battery Management

Advanced Battery Monitoring

We have developed an opt-in push notifications system to automatically remind users when to recharge, ensuring that the jump-starter is always ready to go when needed.

Step-by-Step Interactive Guide

Besides guiding users through the jump-starting process and automatically confirming if they have completed each step correctly, the app also explains error conditions like reverse polarity or over-temperature and provides solutions.

Professional help with the touch of a button

We also introduced easy access to the product’s manual and FAQ’s for quick troubleshooting. Or for more support, users can call or live chat with a technical support team.
