too hot to handle, literally


Ever wonder why your phone dies quicker just a few months after you buy it?

The more you charge your phone, the weaker its battery becomes.


You might’ve felt your phone getting hot while charging at some point. Charging your phone overnight or using fast chargers causes your battery to reach temperatures upwards of 100 degrees Fahrenheit, which destroys your battery over time.

Designed to fit in with your normal overnight charging habits, the Canal Battery Guard uses an experimentally proven charging algorithm that gives your battery rest periods to minimize overheating - the crucial factor in battery degradation.

The battery guard fits between your standard charging brick and USB charging cable, and communicates with an app on your phone. Simply connect via bluetooth and set the time you’ll be waking up in the morning, and the Battery Guard will do the rest.

For more information, check out our white paper which goes more into depth and showcases promising results from preliminary testing:

  • Does this prevent the battery from overheating or overcharging?
    The Canal Battery Guard extends your battery life by preventing overheating, which is the main reason batteries degrade. It does so by giving your battery rest periods while it’s charging overnight so it can cool down, rather than charge continuously and heat up. The Battery Guard also reduces the time your battery spends at higher capacities, which is another cause of battery degradation. There is a misconception that overcharging (i.e. leaving the phone on the charger past 100%) causes the battery to degrade. This a myth; phones are smart enough to stop charging at 100%.
  • Will this affect my charging routine?
    The Canal Battery Guard is unique because it is designed to be used when charging overnight, which is when most of us charge our phones.
  • Is the Battery Guard compatible with all chargers?
    Currently, the Battery Guard comes with both a USB-A and USB-C chargers, which are the most common types.

Patent granted!

Nearly 6 years after applying for a patent for the novel charging method employed by the Battery Guard, the day finally came. On January 2, our patent (US11862772B2) was published!!!

We're incredibly grateful to everyone who has helped us along the way, from the initial conception of the idea in The Art of Making class at University of Pittsburgh Swanson School of Engineering led by Joseph Samosky, to placing 3rd in the Big Idea Center's Randall Family competition in 2020. We also want to thank our patent attorney Kevin Duncan for the many hours of work and helping us with every step of the journey.
