Oukitel WP61 Ultra Review: The Rugged Phone With a Thermal Camera and 20,000mAh Battery
The moment you drop a phone from head height onto concrete on purpose, you find out very quickly whether a company's marketing is honest. I did it a few times on the courtyard tiles with the Oukitel WP61 Ultra, picked it up, and there wasn't a scratch on the screen. That's the whole reason a phone like this exists — I'm sick of babying shiny glass phones that panic the second you drop them. Between filming on location, travelling, and getting out and about here on the Gold Coast, I want something that survives water, dust and knocks and still has battery left at the end of the day.
Today we're testing the Oukitel WP61 Ultra — a 5G Android phone with a professional-grade thermal imaging camera, a ridiculous 20,000mAh battery, a built-in 1,200-lumen camping light and a loudspeaker Oukitel says goes up to around 130dB. We're unboxing it, then taking it out into the real world: dropping it, dunking it, getting it dirty, testing the thermal camera around the house and outdoors, using it as a camping light, and seeing what that huge battery is actually like to live with. Not a marketing brochure — a proper live-with-it-and-see-what-breaks review. And out here in the Australian outdoors, that matters: this is aimed squarely at tradies, construction, field work and anyone whose gear has to last.

01What Is the Oukitel WP61 Ultra?
The WP61 Ultra is a rugged 5G Android phone built to be used, not admired. It's the premium model in the WP61 series — there are other versions in the range, including a walkie-talkie model — and it packs in four things a normal phone simply doesn't have: a real thermal imaging sensor, a 20,000mAh battery, a 1,200-lumen light panel on the back, and a speaker loud enough to hear over tools.
It's rated IP68 and IP69K, with MIL-STD-810H on top, so on paper it should handle water, dust and drops far better than a normal flagship. The ports are sealed, the corners are reinforced, and there are proper exposed screws around the edges. This is aimed at tradies, field engineers, hikers, campers, overlanders, rescue workers — and anyone who just wants a second phone they can throw in a bag and not worry about.
02Unboxing & What's in the Box
Out of the box you're greeted straight away by the phone, and it is a unit. Underneath it you get a USB-A to USB-C cable, a 45W fast charger, the 10W wireless dock it can sit on, a lanyard, a SIM tool and the usual paperwork. No case — because the case is basically built into the phone.
The wireless dock is a smarter inclusion than it first looks. On a sealed rugged phone, the less you're pulling rubber port covers open, the better. Drop it on the dock at night and it's charged and ready in the morning without touching a cable.
03Design & Build: Not Pretending to Be Slim
First impression in the hand: this is not pretending to be slim. It's chunky, it's heavy, and it feels like you could literally hammer tent pegs with it. On the front you get a 6.8-inch display with a tiny punch-hole for the selfie camera, surprisingly thin bezels for a rugged phone, and a pre-applied screen protector.
The back is where all the action is — a big camera module housing the 108MP main camera and the thermal imaging sensor, with that camping light panel sitting right alongside. Around the edges you've got the exposed screws, reinforced corners and rubberised sections that make it easy to grip even when your hands are wet. It doesn't shift in the hand at all, and it's firmly balanced for something this heavy.
The power button doubles as the fingerprint reader, there's a volume rocker, and a programmable side key you can map to the torch, the camera, or — in my case — straight into the thermal imaging app with one press. That single shortcut is the difference between using the thermal camera constantly and forgetting it's in there.
04The Drop Test: Head Height Onto Concrete
Ruggedness first, because that's the whole point of a phone like this. I took it outside at night, made sure everything was sealed, and dropped it from about head height onto the courtyard tiles a few times — screen on, camera rolling.
It landed corner-first and came up absolutely perfect. Not a scratch on the screen. There are a couple of small scuffs on the plastic corner where it took the hit, but everything still works exactly as it did. Risky, I know — and I wouldn't recommend playing cricket with it — but for real-world drops off a workbench, off a ute tailgate or out of a pocket, it's genuinely confidence-inspiring.
05The Water Test: Dunked and Still Filming
Next up, water — because if you're using this out and about, water is the one that gets most phones. IP68 and IP69K means submersion and high-pressure jets, so I filled a tub, hit record on the camera, and dumped it straight in.
I left it under for a while and sloshed it around, then pulled it back out. No drama at all — the camera kept recording the whole time. You could genuinely throw it in a pool. The touchscreen goes a bit weird when it's wet, like any phone does, but the speakers cleared themselves quickly and nothing fogged up.
I use phones at the beach constantly, and knowing that a drop in the shallows isn't the end of the world changes how you shoot. Working in the rain, fishing on a boat, or just dropping it in a puddle on site — it shrugs all of that off.
06The Thermal Imaging Camera: The Real Party Trick
Now the fun bit. The thermal module is a 256×192 sensor running at 25Hz — and that refresh rate is what matters, because it means the image is smooth enough to use for real-time inspection rather than being a laggy novelty overlay.
I mapped the side key to launch it and started around the house: hot water pipes inside the wall, the back of the appliances, my computer to find where it runs hottest, door and window frames to spot where air was leaking (hot air, in my case — it's summer). The level of detail is honestly impressive for something built into a phone. Then I took it outside. I live near a busy road, so I pointed it at the passing cars and watched the different heat levels glow. At night, pointed down the street, you can pick people out as shapes in the dark.
I also tried a more pro-style test on my switchboard and power points. Straight away you can see which breakers and cables are running hotter than the others. For an electrician, HVAC tech or building inspector, that's the kind of quick visual check that saves a lot of time on a job.
The app lets you switch colour palettes, lock temperature ranges, take thermal photos and video, and overlay the normal camera image on the thermal view so you know exactly what you're looking at. The honest framing: this doesn't replace a multi-thousand-dollar dedicated thermal camera. What it does is put a usable one on you all the time — and the one you actually have with you beats the good one sitting back at the workshop.
07The 1,200-Lumen Camping Light & the Loudspeaker
The light panel on the back is 1,200 lumens. To put that in context, it's way brighter than a normal phone flash — it's more like a small dedicated lantern. I turned every light in the house off on a dark night and switched it on, and it lit the whole place up. Put it outside and it lit the entire backyard. You can find whatever gear you're hunting for in a tent or a boot with it.
There are different brightness levels and modes, and Oukitel says not to look into it at full brightness — which I did, obviously, so learn from me and don't. For camping or working late, this is exactly the kind of thing you'd normally have to carry separately. Here it's just part of the phone. When I head off camping, that's the appeal in one device: charge my gear, use the heat sensor, use the light, use the camera.
The loudspeaker is no joke either. Oukitel claims around 130dB. I didn't whip out a sound meter, so treat that figure as theirs and not mine — but it's comfortably loud enough to hear over tools or traffic. It's not an audiophile speaker, so don't expect hi-fi. For speakerphone calls, GPS directions and a bit of music or YouTube at a campsite, it does the job with plenty of volume left over.
08The 20,000mAh Battery: Living With It
On paper, 20,000mAh just sounds ridiculous. In real life, it is pretty ridiculous. This is basically strapping a big power bank onto your phone, and it changes your relationship with charging entirely — I stopped thinking about it.
Used normally with maps, social media, YouTube, Bluetooth, photos and plenty of thermal camera use, you're getting multiple days without a thought. Baby it a bit and I could see a light user stretching it well over a week, up to a couple of weeks. For a work phone that lives in a toolbag or a glovebox, or a long trip off-grid, that peace of mind is as big a feature as the thermal camera.
It also does reverse charging, so it doubles as a chunky power bank for everything else. I charged my main phone and my earbuds from it and it barely made a dent in the battery bar. Charging is 45W wired or 10W wireless on the included dock — and the wireless option means you're not constantly undoing the sealed port cover, which is exactly right on a phone like this.
09Everyday Performance & the Cameras
Day-to-day performance has been fine, which isn't a given on rugged phones. The MediaTek Dimensity 7025 — an octa-core 5G chip — with 12GB of RAM keeps Android 16 feeling snappy. Apps open quickly and multitasking between maps, messages and the camera is smooth. I played some games on it and that 120Hz screen makes them look really good; video looks clear and it runs fast. It's not a budget processor that chokes every time you open Instagram. As a daily driver it's perfectly capable, if you can live with the size and the weight.
Storage is 512GB with microSD expansion up to 2TB, so if you're out in a truck shooting video or thermal footage all day, space isn't going to be your problem.
The 108MP main camera does a solid job in good light — nice detail, plenty of resolution if you want to crop in, punchy colours. I shot down at the Brisbane River and around Brisbane City on a scooter and it held up well. In low light it's not beating the absolute top-end flagships, and I'll be straight with you about that, but for a rugged phone it's more than usable for snapping photos on site or while you're exploring. The 32MP front camera is genuinely good for video calls and pieces to camera, and the mic sounds decent with it — the colours out of the front sensor are a little flatter than I'd want, but the detail is there and it records at good quality for social clips.

The Verdict & Who It's For
What I love most: it replaces four things I'd otherwise carry separately. Phone, thermal camera, campsite lantern, power bank — all in one device I dropped on concrete from head height and dunked underwater without a single failure. The thermal camera mapped to the side key is the feature I use constantly, the 1,200-lumen light is a proper lantern, the 20,000mAh battery means I stopped thinking about charging entirely, and the 120Hz screen and Dimensity 7025 make it genuinely usable as an everyday phone rather than a compromise.
The catches, honestly: it's big and it's heavy — it's not fitting in skinny jeans or running shorts, and if you want a slim pocket phone you should stop reading here. The corner picked up plastic scuffs in the drop test, even though the screen was untouched. Low-light photography isn't near flagship level. The thermal sensor is excellent for what it is, but it isn't replacing a dedicated professional unit. The 130dB speaker figure is Oukitel's, not mine — it's loud, but I didn't measure it. And the touchscreen gets fiddly when wet, same as every phone.
Who's it for? Tradies, field engineers, electricians and building inspectors who'd get daily use out of the thermal camera. Hikers, campers, overlanders, boaties, rescue workers and anyone spending long days away from a power point. And anyone who just wants a second tool phone to throw in a bag and stop worrying about. If you want a slim, fashion-focused phone, this isn't for you — and that's fine, it was never trying to be.

?Frequently Asked Questions
Does the Oukitel WP61 Ultra really have a thermal camera?+
Yes — it's a genuine 256×192 thermal imaging sensor running at 25Hz, built into the rear camera module. That refresh rate makes it smooth enough for real-time inspection work: checking hot water pipes, spotting hot breakers on a switchboard, finding air leaks around window frames, or picking out people and animals in the dark. The app lets you change colour palettes, lock temperature ranges, record thermal photos and video, and overlay the normal camera image. It won't replace a dedicated professional thermal camera, but it's on you every day.
How long does the 20,000mAh battery actually last?+
In normal use — maps, social media, YouTube, Bluetooth, photos and plenty of thermal camera use — you're getting multiple days without thinking about it, and a light user could stretch it well over a week. It also does reverse charging, so it works as a power bank for your other devices; I topped up my main phone and my earbuds from it and barely dented the battery. Charging is 45W wired or 10W wireless on the included dock.
Is the Oukitel WP61 Ultra waterproof?+
It's rated IP68 and IP69K, plus MIL-STD-810H. I filled a tub, dropped it in with the camera recording and sloshed it around — it kept filming the whole time with no issues. The touchscreen behaves oddly when it's wet, like any phone, but the speakers clear themselves quickly and nothing fogged up. Rain, boats, puddles and the beach are all fine.
Will it survive being dropped on concrete?+
In my testing, yes. I dropped it from about head height onto concrete courtyard tiles several times with the screen on. It landed corner-first and picked up a couple of small scuffs on the plastic, but the screen was untouched and everything kept working. It ships with a pre-applied screen protector and doesn't come with a case, because the case is essentially built into the phone.
How bright is the built-in camping light?+
It's 1,200 lumens with multiple brightness levels and modes — far brighter than a standard phone torch and closer to a small dedicated lantern. It lit up an entire dark room and the whole backyard in testing. Don't stare into it at full brightness. For camping or working late, it replaces a light you'd otherwise have to carry separately.
Is the Oukitel WP61 Ultra good as an everyday phone?+
Yes, with one caveat — the size and weight. Inside it's a MediaTek Dimensity 7025 with 12GB of RAM, 512GB of storage (microSD to 2TB), a 6.8-inch 120Hz FHD+ screen and Android 16, plus 5G, NFC payments and GPS. It's smooth for apps, maps and gaming. It's just big and heavy, so plenty of people run one as a second "tool phone" rather than a daily driver.
Who should buy a rugged phone with a thermal camera?+
Tradies, electricians, HVAC techs and building inspectors get the most obvious daily value from the thermal camera. Beyond that it suits hikers, campers, overlanders, boaties, field engineers and rescue workers — anyone spending long days away from power, around water, dust, heat or cold. If you want a slim, fashion-focused phone, this isn't it.
