Four years ago, my then colleague Vlad brought you news of an 18,000mAh battery for a mobile phone. Well, I’m happy to tell you that Avenir Telecom is at it again, only now it’s packing a smartphone into a 28,000mAh battery. In this industry, that’s what we call progress.
The device itself is called the Hard Case P28K, and like its predecessor, it will be sold under the Energizer brand (Avenir licenses the brand from the battery manufacturer). The company claims the P28K’s battery is large enough to last a week of normal use. The device also has a fairly rugged IP69 rating, making it suitable for all kinds of off-grid adventures you might want to go on when you’re away from a charging point.Talk time is rated at 122 hours (or a little over five days), while standby time is up to 2252 hours, or nearly 94 days.
The disadvantage is that it is an absolute unit.exist The P28K hard case is 27.8 mm thick and weighs 570 grams, which is more than three times the thickness and weight of the iPhone 15. So if you want something slim, don’t buy this thing. It can charge quickly at up to 33W, and we’ve followed up with Avenir Telecom for an estimate of how long a full charge will take.
If you have to insist on treating it like a regular smartphone, its specs are just entry-level. There’s no 5G, and its processor is the humble MediaTek MT6789. You get 8GB of RAM, 256GB of storage, three rear cameras, Android 14, and a 6.78-inch 1080p LCD display.
Avenir Telecom plans to sell the Energizer Hard Case P28K for €249.99 when it goes on sale in October this year. It will be available globally, but not in the United States.
Updated February 25 at 3:38 pm ET: The update notes a 33W maximum fast charging speed.
