Based on the specifications Rexing publishes for each model, not independent testing by Trendivation.
Rexing Dash Cams
A dash cam records what happens in front of, behind, or around your car so you have footage if something goes wrong. Consider this category if you want video evidence for insurance disputes, parking incidents, or simply peace of mind on regular drives. What matters most when comparing models: how many camera channels you need (front only, front+rear, or full 4-channel coverage), resolution, and whether you need parking-mode monitoring, which typically requires a separate hardwire kit.
Rexing V1 MAX
- 4K UHD (3840×2160), 170° wide angle (Rexing lists)
- Built-in GPS & Wi-Fi
- Night vision, supercapacitor
- Supports up to 256GB, per Rexing's listing
Rexing C2
- 2K front + 1080p rear (Rexing lists)
- Wi-Fi & Rexing Connect app
- Parking monitor, collision detection
- 1.5" LCD touchscreen
Rexing R4 Pro
- 4 channels: 2K front + 1080p ×3 (Rexing lists)
- Built-in Wi-Fi & GPS
- Parking mode, G-sensor
- 170° wide angle
Rexing M1 Pro (Mirror)
- 1440p front + 1080p rear (Rexing lists)
- 12" IPS touchscreen mirror
- Waterproof backup camera
- Sony IMX335 night vision, per Rexing
Rexing V5
- 4K (3840×2160), modular design (Rexing lists)
- Sony IMX335 sensor
- Add-on rear or cabin camera
- Supercapacitor, up to 256GB
Rexing R88
- 4K front + 4K rear (Rexing lists)
- Dual Sony STARVIS sensors
- 4" touchscreen, 5.8GHz Wi-Fi
- 24/7 parking monitor
How to choose between them: pick by the number of camera channels you actually need, then check resolution and whether parking mode requires extra hardware you'd have to buy separately. Before buying: confirm current resolution, storage limits and included accessories on the product page, since specifications can change between listing updates.
Specifications above come from Rexing's own product listings and have not been independently lab-tested by Trendivation. For a comparison against other dash cam brands, see our AI dash cam collision-alert guide.
Rexing Jump Starters & Tire Inflators
A jump starter restarts a car with a dead battery without needing another vehicle. Consider this category if you drive often, drive alone, or simply want a backup for a battery that occasionally struggles. What matters most: peak-amp rating relative to your engine and battery condition, battery capacity (how many jumps per charge), and whether you also want a built-in tire inflator.
| Model | Peak amps / battery (Rexing lists) | Rexing's stated engine coverage | |
|---|---|---|---|
| Rexing RJ2000 | 2,000A / 16,000mAh | Up to 7L gas / 6L diesel | View on Rexing.com |
| Rexing RJ3000 | 3,000A / 20,000mAh | Up to 8L gas / 8L diesel | View on Rexing.com |
| Rexing RJ4000 | 4,000A / 24,000mAh | Up to 10L gas / 10L diesel | View on Rexing.com |
| Rexing RJ31 3-in-1 | 1,500A / 12,000mAh + 150 PSI inflator | Not specified beyond "1500A peak" in the listing | View on Rexing.com |
Engine-coverage figures above are Rexing's own stated compatibility, not an independent test. Confirm your vehicle's cold-cranking-amp requirement against the current listing before buying.
Example Jump-Starter Peak Amps by Vehicle Type
Example figures only, not a universal requirement. Always check your own vehicle and jump-starter compatibility.
Peak-current requirements vary by vehicle, battery condition and manufacturer guidance, so a single amp number doesn't guarantee suitability for every car. Use the vehicle's owner manual and the jump starter manufacturer's own compatibility information — rather than engine size alone — to decide which model to buy.
A typical jump-start procedure
Illustration of one common sequence — not every unit works identically. Always follow your own unit's manual.
A typical jump-start procedure varies depending on whether you are using jumper cables with another vehicle or a portable jump starter, so treat the steps below as a general shape rather than an exact match for your own equipment. Always follow the instructions supplied with your specific vehicle and jump starter:
- Park close but not touching, and switch everything off on the dead car.
- Connect red (+) to the dead battery, then the other red (+) to the good battery or the jump starter's positive port.
- Connect black (–) to the good battery's negative terminal or the jump starter's negative port.
- Connect the other black (–) to an unpainted metal point on the dead car, away from the battery itself.
- Power on and try to start the dead car; disconnect in reverse order once it's running, powering the unit off first if your manual says to.
- If the vehicle starts, drive for a reasonable period when appropriate to allow the charging system to recharge the battery, or follow the vehicle and battery manufacturer's guidance.
- Always follow your specific unit's own manual — instructions and connection points differ between models and brands.
- Inspect the battery first — a cracked, swollen, leaking or frozen battery should be handled by a professional, not jump-started.
- Never let the red and black clamps touch each other, and keep sparks and flames away from the battery.
- Some units require you to power off before disconnecting the clamps — check whether yours does.
- If you're unsure about your battery's condition or your vehicle's compatibility, consult a mechanic rather than guessing.

If you find yourself needing a jump start often, that can be a sign your battery or alternator needs checking — a scan tool that reads live charging-system data can help. That's covered in the next section.
Rexing OBD2 Diagnostic Scanner
An OBD2 scanner reads the fault codes your car's computer stores, so you can see why a warning light is on before deciding whether to visit a mechanic.
Rexing OBD2 Scanner
- Compatible with OBDII vehicles since 1996, per Rexing
- Reads and clears engine fault codes
- Checks smog readiness
- Shows live data and freeze-frame data
Before buying: confirm your specific vehicle's OBDII compatibility on the current product page. For a wider comparison of scanners with AI-assisted code explanations, see our best OBD2 AI diagnostic scanners guide.
Rexing Wireless CarPlay & Android Auto Adapters
These adapters let you use CarPlay or Android Auto without plugging your phone in every drive.
Rexing CPW-42

Compatibility to check first: the CPW-42 is described as converting wired CarPlay to wireless, which suggests your car needs wired CarPlay already built in. The AI Box's own listing describes it as a standalone adapter rather than a wired-to-wireless converter. Check your car's exact infotainment compatibility on the product page before ordering either one.
