Energizer PowerMax P28: Your Pocket-Sized Power Savior

In 2026, we’re more reliant on our devices than ever. From holographic calls to augmented reality overlays, our smartphones, tablets, and even smart eyewear are constantly drawing power. That’s where the Energizer PowerMax P28 comes in – a portable power bank that packs a serious punch in a surprisingly compact package.

Design and Portability

The P28 sports a sleek, minimalist design. It’s about the size of a credit card, albeit significantly thicker, and easily slips into a pocket or bag. The matte finish resists fingerprints, and the build quality feels solid and durable. A small LED display shows the remaining battery percentage, a welcome addition compared to the more common 4-LED indicator systems.

Performance and Features

This power bank boasts a 28,000mAh capacity, enough to fully charge a modern smartphone 5-7 times, or a tablet 2-3 times. It features both USB-A and USB-C ports, supporting Power Delivery (PD) 3.0 for fast charging. I was able to charge my Galaxy S30 from 20% to 80% in just under 40 minutes using the USB-C port. It also supports pass-through charging, so you can charge the power bank itself while simultaneously charging your devices.

One of the standout features is its integrated GaN (Gallium Nitride) technology. This allows for a smaller and more efficient charging circuit, generating less heat and providing a faster charging experience overall. The P28 also includes built-in safety features like overcharge protection, short-circuit protection, and temperature control, giving you peace of mind while charging.

• Excellent capacity for its size.
• Fast charging with Power Delivery 3.0.
• Compact and portable design.

Conclusion

The Energizer PowerMax P28 is an excellent portable power bank for anyone who needs a reliable and efficient way to keep their devices charged on the go. Its combination of high capacity, fast charging, and compact design makes it a must-have accessory in 2026. While the lack of wireless charging might be a dealbreaker for some, the overall performance and features make it a worthwhile investment. I highly recommend it.
