'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

Externally, the Power Armor 18T is a highly ruggedized smartphone that's built to take a severe battering. It meets a whole array of standards, including IP68, IP69K, and MIL-STD-810G, which means that it's happy to be immersed in water at depths down to 1.5 meters for 30 minutes, exposed to high-pressure water jets and steam cleaning, and dropped from 1.2-meter heights. Also, it resists dust getting in, shrugs off any acid spills, and it is happy to spend time in low-pressure environments that can destroy other smartphones.
It's a tough smartphone. I know, because mine's been out in the rain and ice, got dropped into mud, fell off the tailgate of my truck, and got left outside in a thunderstorm when I forgot about it while reviewing it.
At the core of the Power Armor 18T is a 2.4GHz Arm Cortex-A78 CPU paired with the Mali-G68 GPU. That's enough power to keep the handset running super-smooth at all times. This is paired with 12GB of physical RAM and the option to augment this with 5GB of virtual RAM for when the going gets tough.
I've found 12GB of RAM to be more than ample and have not seen the need to boost this to the full 17GB.
But the faster processor, big RAM boost, and doubling of storage capacity are all things I really appreciate in this upgrade.
The power is supplied by an enormous 9600mAh lithium-ion polymer battery, which is charged via the USB-C port or wireless charging. The wireless charging is a big upgrade for me because it means not having to open that waterproof flap on the USB-C port if I'm outside in poor weather conditions.
The 108-megapixel rear camera featuring a huge ISOCELL HM2 1/1.52-inch sensor delivers some really good photos, even in standard resolution. I've played with this camera in a variety of conditions and it's good. Not iPhone Pro Max good, but still very good for a smartphone that's a fraction of the price of the iPhone Pro Max.
Do you need 108-megapixel photos?
I can see some minor differences between the standard and high-resolution photos if I really look closely, but I have to admit that I'm happy to stick to regular photos unless I need an image that I might later need to edit heavily or crop a lot.
The 32-megapixel front camera is also pretty good, but I'm not sure if we really need that many megapixels in a front camera as it's hard to see real-world improvements over cameras with a lot lower megapixel counts.
But megapixel counts help sell, and as sensors get cheaper, the megapixel counts will go up and up.
My favorite features
On the side of the Power Armor 18T is a port for an endoscope. The Ulefone endoscope (sold separately) features a 2-meter cable, and is rated to IP67. This is perfect for poking into areas where you can't get your eyeballs, and is a great tool for engineers. There are a lot of USB-C endoscopes available, but the fact that this one doesn't take up the USB-C port is handy
The real star of the show for me is the FLIR Lepton 3.5 thermal imaging camera. With 160 x 120 resolution and a temperature range of -10℃ - 400℃, this is an amazing diagnostic tool for technicians.
The thermal camera has four times the resolution of the previous generation of thermal cameras, and that makes for better, crisper, more detailed thermal images.
You can check for overheating components, HVAC issues, doors and windows leaking your precious HVAC heat or cold into the outdoors, car issues, and much more.
At $699, the Ulefone Power Armor 18T is in no way cheap, but after using its predecessor for two years, and then using this one for a few weeks, I'm confident that this device can pay for itself. It's the perfect smartphone for outdoor workers, engineers, and first responders looking for a rugged smartphone that doesn't compromise when it comes to power, performance, and display quality.
