2. Wi-Fi 6 Transfer
3. ADAS 2.0 for Advanced Safety
4. Smart Voice Control

The DDPAI Z50 Pro dash cam comes packed with high-end features tailored for demanding drivers who value quality, connectivity, and safety. At the heart of the device is its dual-channel video recording system, capable of capturing footage in true 4K resolution (3840 x 2160 at 25 FPS) for the front camera, and Full HD (1920 x 1080 at 25 FPS) for the rear. While 25 FPS might be sufficient for most driving scenarios, the absence of a 30 or 60 FPS option is noticeable, especially when smoother playback or better detail in motion is needed—such as reading license plates in fast-moving traffic.

The 3.0-inch LCD screen is large enough to preview footage clearly, adjust settings easily, and navigate menus comfortably, although some users may find the screen size contributes to the camera’s relatively bulky footprint. The lens features a wide field of view—143° in the front and 124° in the rear—ensuring a broad capture area that minimizes blind spots. Additionally, the wide F1.8 and F2.0 apertures help gather more light, improving video brightness, especially in low-light environments.

Under the hood, the dash cam supports the modern AI.265 encoding, which is a more efficient video compression technology compared to the traditional H.264. This means you can store more video footage on the same memory card without sacrificing quality. Speaking of storage, the device supports microSD cards up to 512 GB, but only if the card meets the U3 (UHS-3) standard or higher, ensuring fast writing speeds to handle high-resolution recordings.

In terms of connectivity, the Z50 Pro is ahead of the curve. It includes Wi-Fi 6 support for faster file transfers and Bluetooth BLE 5.1 for low-energy device communication. GNSS support is comprehensive, offering GPS, BDS, and GLONASS, which enables precise route tracking and geotagging of your recordings. For safety and power reliability, the device is equipped with a supercapacitor instead of a traditional battery—ideal for enduring extreme temperatures and preventing data corruption in the event of sudden power loss.

The camera also integrates a 3-axis G-sensor (IMU), essential for detecting collisions or sudden movements, which automatically saves and locks important footage to prevent it from being overwritten. On top of that, smart features like ADAS 2.0 (Advanced Driver Assistance System) and smart voice control add an extra layer of intelligence and hands-free convenience.

Physically, the dash cam is compact yet solid, measuring 83mm x 64.7mm x 34.8mm and weighing 187 grams. Its USB Type-C connection ensures fast power delivery and ease of setup. The device is designed to operate in harsh conditions, with an operational temperature range from -20°C to 70°C and a storage range from -40°C to 85°C—making it suitable for both hot summers and cold winters.

Video test with video sample

Each 1-minute front video file recorded by the DDPAI Z50 Pro is approximately 200 MB, while the rear camera footage takes up around 40 MB per minute. The camera records in the widely compatible MP4 format and uses either AI.265 or H.264 encoding, offering a balance between video quality and file size. The AI.265 codec is especially efficient, allowing longer recordings on a memory card without a noticeable drop in visual fidelity.

In daylight conditions, both the front and rear cameras deliver relatively sharp and detailed footage, with accurate exposure and decent color reproduction, though some users might find the colors a bit pale. The 4K resolution of the front camera especially shines during well-lit scenes, clearly capturing surrounding vehicles, road signs, and traffic conditions.

However, nighttime performance is noticeably weaker. While overall visibility is acceptable thanks to the wide aperture lenses (F1.8 front, F2.0 rear), reading license plates in low-light scenarios can be difficult, particularly when there’s motion or glare from headlights. This could be a concern in the event of an incident during nighttime driving, where clear identification of vehicles may be essential.

Despite this, the frame-to-frame clarity is fairly consistent, and there are no significant issues with dropped frames or stuttering, even in challenging lighting. It’s worth noting that all footage is stored in 1-minute segments, with no current option to adjust the clip length, which could be a limitation for those who prefer longer continuous recordings.

Video samples include both day and night conditions, showcasing real-world performance from both camera modules. These tests give a good representation of what to expect during typical urban or highway driving.

Cons

• Only 25 FPS – No option for 30 or 60 FPS, even in lower resolutions
• One-minute video segments only – No setting to change clip duration
• Night visibility – License plates are not clearly visible
• Not detachable mount – but it’s adjustable
• Large size – 3-inch screen makes the camera bulkier than some may prefer
• Color quality – Video colors appear slightly pale and washed out
• Not detachable – The camera is fixed once mounted

Pros

• Fast and responsive mobile app
• Good microphone quality
• 4K front + 1080p rear recording
• Decent image clarity during daytime
• Voice control support
• Wi-Fi 6 and Bluetooth 5.1 connectivity
• GNSS tracking (GPS, GLONASS, etc.)

Final thoughts

The DDPAI Z50 Pro is a solid 4K dash cam with impressive features like Wi-Fi 6, voice control, ADAS, 4G and GPS. However, the lack of frame rate options and mediocre low-light performance might be dealbreakers for some users. If DDPAI adds support for 30/60 FPS and improves nighttime clarity in future models or updates, this dash cam could be among the best in its class.

Recommendation: Great for users who prioritize daytime clarity and smart features. Less ideal for those needing perfect night performance or smoother frame rates.

Xiaomi makes almost everything, even toothbrushes. Soocas X3 is a rebranded product (like most of Xiaomi stuff) made by Soocare Technology Co. Ltd. Let’s check if it’s worth buying it.

Package, design and specifications

It comes in a nice, simple package

Here is what you see when you open it. There is another box inside (you can see it on the right side of the photo) with toothbrush head, manual and charger.

Basically there’s toothbrush with protection cover, one toothbrush head (common cleaning type) with protection cover, wireless charger (chinese plug), chinese manual and that’s it! I think it’s worth to buy additional toothbrush heads, because you need to change them once per 3 months.

Toothbrush charger model is: X3CW. It has IPX7 waterproof level, you can plug it to 110-240V and it’s 3W. The Soocas logo starts to illuminate when it’s plugged in.

There is chinese plug, so you may need to buy a proper plug adapter.

What about specs? There we go:

1. Handle input: 3.7V
2. Charger input: 110-240V ~50-60Hz, 3W
3. IPX7 waterproof standard
4. Made in China by Soocare (Shenzhen) Technology Co. Ltd.

You can also check product’s originality. Here is toothbrush itself. I think everyone will love its design – it’s simple and elegant.

Usage

Basically there are 4 cleaning modes that you can choose from:

1. Standard – about 31000 vibrations per minute. It’s for cleaning oral cavity, removing dental plaque and other particles. I’m using it daily.
2. Sensitive – less vibrations per minute than standard. Intended for people with gums inflammation, tooth implants or briquettes.
3. Beginner mode – use this mode if your gums are not in good condition or you’re using it for the first time (Xiaomi says you should use this mode for a week before you switch to another one).
4. Whitening or individual – 34800-37200 vibrations per minute. It is intended to eliminate plaque after drinking coffee, smoking etc.

As I said I’m using first mode (the top mode) and I think it’s the best for everyday usage if you have no problem with gums or teeths. It will clean your teeths better than manual toothbrush (especially if you use manual one in a wrong way), but in my opinion it’s not the best at cleaning tongue – toothbrush head is just too small and soft. It’s better to use manual toothbrush for tongue cleaning.

What about cleaning technique? Put a little bit of toothpaste on toothbrush head and spread it all over your teeths (just like with manual one). Choose proper cleaning mode (it will be saved after cleaning, so you won’t have to choose it again next time) and start cleaning your teeths’s side (with 45 degree angle) and top moving slowly. Soocas X3 works for 2 minutes with 3 short breaks – after 30, 60 and 90 seconds. Try to clean left bottom area in 30 seconds, then right bottom in another 30 seconds et cetera. You can clean for another 2 minutes if you want.

Battery life

There are three dots showing battery level (3 dots = 100%, 2 dots = 66%, 1 dot = 33%). Battery capacity is 1000 mAh. I’m using it for 2 weeks, but I was charging it – my bad.

I’ve charged it fully today (02.12.2017) and I won’t charge it anymore from now on so I can update this paragraph when battery will be empty (for your information – I’m using it like 3 times per day).

Update (17.12.2017): after 15 days there are 2 green dots. Very good result.

Update (28.12.2017): after 26 days red dot appeared, so I’ve stopped the test not to damage battery. 26 days is the same as specification says, so it’s excellent!

Update (04.11.2018): After (almost) 1 year of using this toothbrush I’m going to make next test. I’ve charged it today, so we’ll see how long it will work this time! Update (02.12.2018): There we go. It’s still the same (even more) after 1 year – 28 days! Basically battery used in this toothbrush is high quality.

Here is the red dot at the end of the test:

I’ve started charging on 28.12.2017 16:00 CET. On 29.12.2017 6:00 CET it was fully charged, so you need at least 14 hours to charge battery fully.

Waterproof test

Here’s a short YouTube video showing Soocas X3 being covered with water.

Well, it is waterproof!

Application

There is an english application for Android. You can get it here: https://apkpure.com/soocas/com.soocare.international

Install it, create account, click on top left button, go to “My toothbrush” and bind it. You have to give all permissions to Soocas application to make binding work.

You can set brushing time to 2.5 minutes and last 10/30 seconds cleaning method.

Pros and cons

Pros:

1. It’s really nice looking toothbrush
2. Cleans your teeths better than manual toothbrush
3. Four cleaning modes – I think that’s enough for everyone
4. Long battery working time (26 days tested). After 1 year 28 days tested.
5. It’s customizable via app

Cons:

1. Not the best in tongue cleaning (just buy tongue cleaner)
2. “Long” charging time (14 hours tested)
3. No infinite work mode

This toothbrush is like the movie “The Green Mile” – it’s really good. I recommend that product.
