Why campus days drain batteries
Big lecture halls and concrete buildings often have weak signal, and a phone searching for service uses more power. Add the screen time from notes, maps, and messages between classes, and a morning charge can be gone by mid-afternoon.
The last 20% matters most, because that is the charge that has to cover the bus home, the ride request, or the call to say you are running late.
Three ways to stay charged
An outlet is free, but it keeps you in the seat next to it, and the good seats by the wall go first. Your own power bank works if you charged it last night and packed a cable. A Juiceboxx rental works when you forgot both.
A rental costs $2 for each 30 minutes, capped at $12 per 24-hour day. A $20 hold on your card is released when you return the power bank.
How a rental fits between classes
Open the app, scan the station, and take a charged power bank with built-in cables. Plug in and head to your next class with the phone in your pocket. When you are done, return it to any Juiceboxx station. The return guide covers the details.
If you have never rented before, the app guide walks through the scan step by step.
When a rental is not the right answer
If you will sit in one library seat for three hours next to an outlet, a wall charger is the cheapest choice. A rental is for the days when you keep moving.

Plan the return before plans change
A friend offers a ride, the study group moves across town, and the power bank ends up back at the dorm in a jacket pocket. It happens. Decide where you will return it at the start of the day, and drop it on your way past.
You have 48 hours to return it before the $20 hold is charged.
