Charging and power on the road

Long travel days, camping trips and power cuts all have one thing in common: devices that run out of power. Diabetes tech can include a pump, a CGM receiver or phone, a pump controller, and sometimes a meter. Each has its own battery and charging needs. This guide helps you keep them all running.

Know what each device needs

Make a list of every device you rely on and how it's powered. Some pumps are rechargeable, and some use replaceable batteries. Some pumps and CGM systems are controlled from a separate handheld device. Many CGM sensors have a built-in battery that lasts the life of the sensor, but the phone or receiver showing the readings still needs charging.

Pack a power pouch

One small pouch with: a power bank with enough capacity for at least a full charge of your phone and pump; the right cable for each device, plus a spare; a wall plug with more than one port; and spare batteries for any device that uses them. For international travel, add a plug adapter.

Charge on a schedule

Top up devices at the same times each day, such as during breakfast and dinner, rather than waiting for a low-battery warning. Before a long day out, start with everything fully charged.

Phones are the weak link

If your phone shows your CGM or controls your pump, it's now a medical device as well as a phone. Low-power modes, battery optimization settings and app restrictions can stop diabetes apps from working in the background. Check your device maker's guidance on recommended phone settings. Keep your phone out of extreme heat and cold, both of which drain the battery.

Have a backup plan

If a device dies and can't be charged, you need a way to keep going. Keep a meter and strips in case your CGM can't be read, and carry the backup insulin plan your care team gave you in case your pump stops. Write down your pump settings on paper.
