Acebeam X75 Brightest Powerbank Flashlight Review
Acebeam has released the X75, the “brightest powerbank” flashlight. My version uses 12 Cree XHP70.3 HI emitters and has great throw! Read on!
Official Specs and Features
Here’s a referral link to the Acebeam X75 brightest powerbank flashlight product page.
Versions
Just one body of the Acebeam X75 brightest powerbank flashlight is available, but there are three emitter options. There’s Cree XHP70.3 HI (seen here). Also available are Cree XHP70.2 (5000K), and Cree XHP70.2 (6500K). Two packages are available, too – one includes a 60W charger and the other includes a 100W charger. Either can be US, EU, UK, or AU plugs.
There also appears to be a white “Micro-ARC” version, which is of course gorgeous. 😀
Price
Depending on which package setup and emitter option you select, this light ranges from $399.90 to $492.80. You can access the Acebeam page through my referral link for the Acebeam X75 brightest powerbank flashlight.

Short Review
This is a fantastic light! I enjoy that mine has Cree XHP70.3 HI emitters because I prefer the higher throw out of big lights like this. Otherwise, everything about the light is very good. The user interface is good. Handling is good. The fan works well. All in all, this is a great light! Even at $400 or so, it seems like a great choice.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Package and Manual
Build Quality and Disassembly
Build quality is great, of course, because Acebeam has high quality standards. The Acebeam X75 brightest powerbank flashlight is no exception to that. It feels very much like the Acebeam X50 (which I guess makes sense because it has the “X” lineage.”) I love the X50 (and have reviewed two versions including the High CRI version, which is a personal favorite.)
Acebeam includes a spare fan. This strikes me… I would have never thought the fan might need to be replaced except for the fact that they include one. I suppose this also demonstrates that it’s a) possible to and b) probably fairly easy to replace this fan if needed.
You can see in the head here that there’s a bunch of copper! Pushing out 67,000 lumens will require a bunch of cooling…
This silicone bezel is easily removable and also has a color change feature to tell you when the light is hot. I think it should be fairly obvious when the light is hot, though.
On the tailcap is a bunch of text. It’s very descriptive text. Good text.
Along with the silicone accessory bezel and copper cooling fins, the head has some nice deep cooling fins built in.
Again, the silicone bezel removes easily. The light looks great without this bezel too. And I don’t car about the color change feature but this soft bezel is super nice for just moving the light around and placing it on tables and surfaces or whatever… it adds a nice bit of “softness” to moving the light. That sounds weird but it’s not weird, you’re weird. This bezel is great!
To access the interchangeable fan, these four Torx screws must be removed. This also removes the handle. Removing the handle also removes the controls, so the light can’t be operated with the handle.
The tailcap unscrews easily. Threads here are long and excessively lubricated.
The inside tailcap has a fair amount of text, too. There are a couple of indicating LEDs there as well.
The head comes off the body easily enough by unscrewing. There’s nothing to really mess with on this side of things – all of the charging and powerbanking happens through the tailcap end.
More cooling in the head in an unusual and neat way. These holes provide more surface area for potential cooling. These holes are actually air inlets, too, which is a clever way to manage air flow.
Size and Comps
Size: 176(Length) x 92(Head Diameter) x 127(Height including handle) mm / 6.93 x 3.62 x 5″ inch
Weight: 1240 g/43.7 oz (Including battery pack)
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
Retention and Carry
The Acebeam X75 brightest powerbank flashlight has two means of retention. First is the handle, which more importantly has the switches for controlling the output and fan.
Next up is this UNC1/4″ threaded connector that allows easy attachment of the Acebeam X75 brightest powerbank flashlight to tripods and the like.
There is no nylon pouch or holster for carrying the Acebeam X75 brightest powerbank flashlight. The permanently affixed handle would complicate that anyway.
Power and Runtime
Acebeam says that the battery is a “built-in 14.4V/4250mAh Rechargeable Li-ion battery pack ( 4 x 21700 Li-ion Batteries).” That battery pack is in the handle and is not user-serviceable.
Here are a number of runtime graphs. I tested the Acebeam X75 brightest powerbank flashlight in “Eco” mode – note that total output for each is the same, but the stepdowns (and thus runtimes) are a bit different.
Charging
Charging of the Acebeam X75 brightest powerbank flashlight is by way of a USB-C charging port that is accessed by removing the tailcap.
Acebeam includes a charging cable – USB-C to USB-C.
Acebeam also includes a wall ward that has a single USB-C plug. There are two options – a 60W and 100W version. Mine appears to be a “65W” version.
Charging works great, and in my testing can be up to 20V charging. 20V at 3A or so does in fact mean this is charging at 60W or so, and that does mean charging is very quick. It will also charge from USB-A to USB-C connections, just at a much slower rate.
Powerbank
That same USB-C port that’s used for charging can be used as a powerbank. In my tests, it’s a very capable powerbank device.

Pulse Width Modulation
None of the modes use PWM.
Here you can see a “baseline” – a chart with almost no light hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
As stated above, the switch for the Acebeam X75 brightest powerbank flashlight is on the handle, and there are no other switches. That means that the handle is required for any operation of the light. That’s fine, and I like that as much as if I had to hunt around on the light for a switch while holding the handle.
There are two e-switches on the handle. In the photo above, the upper (bigger) (“Auxillary”) switch controls the fan while the lower (smaller) (“Main”) switch controls the light output.
The switch covers are different sizes (as seen above) but also different heights (as seen below). The LED switch is more proud.
Aside from those two e-switches, there’s a physical lockout switch on the handle. This physically disables the switches. Note that it does not physically disconnect the battery, so any parasitic drain that is internal is not affected by locking out this switch. This is simply a switch to prevent accidental activation and the like.
I do wish there was a way to physically disconnect the battery. Even unscrewing the body from the head doesn’t quite achieve what I want.
When the Acebeam X75 brightest powerbank flashlight is in use, there’s a very nice indicator on the body to the right of the switches.
Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click Main switch | On (Mode memory) |
| Any | Double Click Main Switch | Turbo (and activates fan) |
| Any | Triple Click Main Switch | Strobe (and activates fan) |
| On | Hold Main Switch | Mode advance (Low>Mid1>Mid2>High) |
| On | Hold Auxiliary Switch | Momentary Turbo |
| Off | Hold Auxiliary Switch >3s | Iterate fan state (on/off) |
| Off | Click Auxiliary Switch 10x | Iterate Eco/Power modes |
| On | Click Main Switch | Off |
| Any | Long press Main Switch | Ultra-Low |
LED and Beam
While there are three options, my version of the Acebeam X75 brightest powerbank flashlight uses Cree XHP70.3 HI emitters. The product page lists the XHP70.2 emitters as the “HI” version, but in the photos, they very much look like the domed version to me. Either way, that’s available in 6500K and 5000K.
So if you want strictly high output, maybe go with XHP70.2 in 6500K, but if you will tradeoff some output for more throw, by all means, get the 70.3 HI version.
The bezel has some shape, so you know I’m a fan of that.
Note how this silicone attachment fits – it is sort of “generically keyed” – the bezel teeth fit into slots. So there’s a right way and wrong way to reattach this accessory.
LED Color Report (CRI and CCT)
CCT on this Cree XHP70.3 HI version is claimed at 6500K. That’s bout right for the lowest output (around 6400K). Even on the second-highest output, the CCT only creeps up into the 6700K range (which is fine for a 6500K rating). On the highest of highs, this light is around 7200K, which is very cool. CRI is low, at around 70.
Beamshots
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Conclusion
What I like
- Massive output
- Great throw!
- Very quick charging
- USB-C charging
- Powerbank feature works well
- User interface is nice
- Internal fan is acceptable (it’s not overly loud, that is – it seems like a nice quality fan)
What I don’t like
- Expensive
- Built-in battery that is not user-serviceable
