1. Energizer Hard CaseP28K

The Energizer Hard CaseP28K stands out with its super jumbo battery capacity of 28,000 mAh, enabling it to last not just a day but several days, potentially even a week.
Its rugged design is both sturdy and resilient, featuring IP68/IP69 ratings that make it dust and water-resistant up to a depth of 1.2 meters for 30 minutes. The device includes a sizable 6.7-inch IPS LCD screen with Full HD+ resolution that can provide ample visual real estate.
It is driven by the Helio G99, which is suitable for extended multitasking sessions. Additionally, it includes 8 GB of LPDDR4x RAM and 256 GB of UFS 2.2 internal storage, with a dedicated microSD slot for further expansion. The main camera is a 60 MP unit capable of recording videos up to 2K at 30 FPS.
However, despite its 33W fast charging capability, the substantial battery still takes a long time to charge fully. The device lacks a reverse charging feature, which could have been useful for powering other gadgets.
The body is quite bulky, with a thickness of 27.8 mm and a weight of 570 grams, making it less portable. It relies solely on the main camera, with other cameras being rather unimpressive. Connectivity options and sensors are limited, and the device is equipped with only a mono speaker, which may affect the audio experience.
2. DOOGEE V Max Plus

DOOGEE V Max Plus stands out with its massive 22,000 mAh battery, claimed to last up to 142 hours for music playback.
Built for extreme durability, it is dustproof, waterproof, and shock-resistant, even capable of withstanding high-pressure hot water sprays. On the back, there is an RGB V-shaped light that signals incoming notifications.
The phone features a 120 Hz IPS display protected by Gorilla Glass 5, ensuring both smooth visuals and added durability.
Powered by the Dimensity 7050 SoC, it delivers solid performance for everyday tasks and casual gaming. With 16 GB of RAM and 512 GB of internal storage, it offers plenty of space for apps and files, and the microSD slot allows expansion up to 2 TB.

Additionally, an FM radio is included for entertainment without relying on an internet connection.
The phone is equipped with a complete set of sensors, including a gyroscope and a fingerprint scanner integrated into the power button. It runs on a clean, ad-free Android operating system with minimal customization, providing a straightforward and smooth user experience.
However, there are a few drawbacks. The absence of a 3.5mm headphone jack means users will need a converter to use wired earphones.
While the device supports 33W fast charging, it still takes a long time to fully recharge the enormous 22,000 mAh battery. Another trade-off is its thick and heavy build, weighing around 500 grams—though this is expected for a rugged phone designed for durability.
3. Doogee V Max Pro

Doogee V Max Pro comes with a massive 22,000 mAh battery, which is claimed to provide up to 142 hours of music playback. Designed for durability, its body is resistant to dust, water, and shocks.

The phone also includes stereo speakers, which is great for the audio experience when watching videos or playing games. For those who enjoy radio, it still has an FM radio feature, allowing free entertainment without needing an internet connection.
Equipped with a full range of sensors, including a gyroscope and a fingerprint scanner on the power button, the Doogee V Max Pro ensures a smooth user experience. It runs on a clean, ad-free Android operating system that requires minimal customization.
However, the phone no longer has a 3.5mm headphone jack, so users will need a converter to use wired earphones.
While it supports 33W fast charging, recharging the massive 22,000 mAh battery still takes a long time. Additionally, the phone is quite thick and heavy, weighing around 500 grams, but this is expected for a rugged device designed for durability.
4. Oukitel WP33 Pro

The Oukitel WP33 Pro was released globally in January 2024, priced at 399,99 US Dollars. This outdoor phone has a very large battery capacity of 22,000 mAh.

It supports fast charging with 33 watts of power. This isn't the fastest for its price range, especially for a 22,000 mAh battery, as it takes about 5 hours to fully charge.
However, the large battery size means users can use the 18-watt reverse fast charging feature to charge other devices. You just need a USB-C to USB-C cable. It's a shame this phone doesn't have wireless charging.

The Ulefone Armor 24 is also useful in emergencies. For instance, if a friend's phone runs out of battery, this phone can charge other devices through reverse charging. However, this only uses 10 watts of power, so charging another battery might take a while.
With the price it offers, this phone provides NFC, a side-mounted fingerprint sensor, IP68 and IP69K resistance, and a flashlight with up to 1,000 lumens brightness. On the downside, it lacks 5G support, using the Helio G96 chip, commonly found in cheaper phones.

A 64 MP night vision camera with two infrared lights adds to its capabilities. Video recording reaches up to 4K at 30 FPS, with gyro-EIS for stabilization. The phone is also equipped with infrared, NFC, a gyroscope, a barometer, and a compass.
However, the rugged design contributes to a bulky body, with a thickness of up to 25.5 mm and a weight of 600 grams. The front camera is limited to 1080p video recording at 30 FPS, and the device only features a mono speaker, which might impact the audio experience.
