Energizer Hard Case P28K World’s Largest 28,000 mAh Battery!

The phone is called the Energizer Hard Case P28K. Avenir Telecom does not appear to have a website or press release for it, and there is only one official photo, although The Verge saw the phone during the expo. Avenir is not achieving these large battery sizes by magic; the previous 18,000 mAh phone was 18 mm thick, but this 28,000 mAh phone is a monstrous 27.8 mm thick. That’s more than three iPhones stacked on top of one another.

With this cell capacity, you could think of it as a portable power bank with built-in smartphone functions, or an entry-level Android mobile on steroids. In any case, the large battery size should be sufficient for a long outdoor journey or in areas with obvious power shortages.

According to Avenir, a single full charge powers the Energizer Hard Case P28K for a week of regular smartphone usage or approximately 122 hours of continuous cellular call time. Even more astonishing is the device’s ability to last up to 94 days in standby mode.

Aside from fueling itself, the Energizer P28K can also function as an independent power bank, allowing you to fully charge another phone while still having a few days to spare. And speaking of charging, it has a 33-watt rating. However, we have yet to check with Avenir Telecom how long the P28K should take to fully recharge.
