1. What is the TK905?
The TK905 is a 4G LTE magnetic GPS tracker with an integrated rechargeable battery, designed for covert or semi-permanent asset tracking without the need for hardwiring. It communicates via 4G LTE (with 2G fallback) and supports the full GNSS constellation including GPS, GLONASS, BeiDou, and Galileo for accurate positioning across Australia.
Unlike hardwired fleet trackers such as the Teltonika FMC920 or FMC130, the TK905 doesn't require connection to a vehicle's power supply or CAN bus. This makes it significantly easier to deploy — but also means it has inherent limitations for comprehensive fleet management.

3. Real-Time Tracking Performance
In real-world testing across Sydney metro and regional NSW, the TK905 performs reliably for location tracking. With a 4G LTE connection, position updates are fast and accurate in metro areas including Parramatta CBD, Blacktown, Liverpool, and the Sydney CBD.
In regional areas — including routes between Sydney and Penrith, out toward the Blue Mountains, or south toward Campbelltown and Wollongong — coverage is dependent on the 4G network. In areas where 4G drops, the device falls back to 2G, which can reduce update frequency.
GNSS accuracy is strong thanks to multi-constellation support. Cold start acquisition (first fix from power-on) typically takes 30–60 seconds in open sky conditions. Urban canyon performance is adequate for most fleet tracking purposes.
Tracking interval note: Battery life and tracking frequency are directly linked. At 10-second intervals, battery life drops significantly. Most fleet operators set 30–60 second intervals to balance real-time visibility with battery longevity.
4. Battery Life: How Long Does It Actually Last?
The TK905's 10,000 mAh battery is its headline feature — and the claimed 90-day battery life is achievable, but only under specific conditions.
| Tracking Mode | Approximate Battery Life |
|---|---|
| Real-time (30-sec intervals) | 7–14 days |
| Standard (5-min intervals) | 30–45 days |
| Low frequency (1-hour intervals) | 60–90 days |
| Standby/sleep mode | Up to 90+ days |
For active fleet vehicles that need real-time or near-real-time tracking, expect to recharge the TK905 every 1–2 weeks. This is manageable for small fleets but becomes operationally demanding as fleet size grows.
For asset tracking — trailers, containers, equipment, or vehicles in long-term storage — the TK905 excels. Set it to hourly or 4-hourly updates and it can run for months without intervention.
5. Installation: Magnetic Mount vs Hardwired
The TK905's magnetic base is strong enough to hold securely under most vehicles, including utes, vans, and light trucks. For covert tracking, it's typically placed in a wheel arch, under a chassis rail, or behind a bumper.
Magnetic mount advantages:
- No installation required — deploy in minutes
- Easy to move between vehicles
- No vehicle modification or wiring
- Ideal for rental vehicles, investigations, or temporary tracking
Magnetic mount limitations:
- Can be removed or fall off on rough terrain
- No connection to vehicle power — battery must be manually recharged
- No CAN bus data (fuel, RPM, engine health)
- Not tamper-proof without additional securing measures
For fleets requiring permanent, tamper-resistant installation with vehicle data integration, a hardwired tracker like the FMC920 or FMC130 is the more appropriate solution. We regularly install both at Techtonika Autolink depending on the use case.
6. Geofencing and Alert Features
The TK905 supports geofencing zones — virtual boundaries that trigger alerts when a vehicle enters or exits a defined area. This is particularly useful for:
- After-hours movement alerts (vehicle moved outside business hours)
- Boundary alerts for high-value assets stored in yards in Blacktown, Penrith, or Campbelltown
- Theft detection for equipment left on construction sites overnight
- Monitoring rental vehicles that should stay within a service region
The device also features motion detection alerts via its built-in accelerometer — the device wakes from sleep mode when movement is detected and immediately sends a position update. This is excellent for theft prevention on parked assets.
An SOS button is included for personal safety applications — relevant for lone workers or security personnel in NSW.
7. App and Platform Experience
The TK905 is typically paired with a tracking platform app or web dashboard. Platform quality varies depending on the supplier — at Techtonika Autolink, we configure TK905 devices with reliable Australian-hosted or low-latency platforms that provide:
- Live map tracking
- Trip history and playback
- Geofence alerts via SMS or email
- Battery level monitoring
- Speed alerts
- Basic reporting (distance, stops, trips)
Note that without CAN bus integration, the TK905 cannot provide fuel consumption, engine RPM, coolant temperature, or fault code data. For these insights, a hardwired CAN bus tracker is required.
8. TK905 in Australian Conditions
Australia's climate presents specific challenges for GPS tracking hardware — extreme heat in Western Sydney summers, dust on construction sites, and water exposure in coastal or wet weather conditions.
The TK905's IP67 rating means it's fully dust-tight and can withstand immersion in water up to 1 metre for 30 minutes — suitable for most Australian outdoor conditions. The magnetic mount holds well on steel surfaces but should be checked periodically on vehicles operating in high-vibration environments like construction sites.
Battery performance can be slightly reduced in extreme heat (above 45°C), which is relevant for vehicles parked in direct sun in Western Sydney during summer. We recommend placing the device in a shaded location under the vehicle where possible.
9. Who is the TK905 Best For?
The TK905 is an excellent choice for:
- Small business owners wanting affordable, no-installation tracking for 1–5 vehicles
- Asset tracking — trailers, generators, boats, caravans, and equipment in Sydney and NSW
- Car rental and leasing businesses needing flexible, vehicle-agnostic tracking
- Tradies wanting to track their ute or van without committing to a hardwired install
- Theft recovery — covert placement makes it hard for thieves to locate and remove
- Temporary deployments — event vehicles, hired plant equipment, short-term projects
The TK905 is NOT the right choice if you need:
- Real-time CAN bus data (fuel, RPM, engine health)
- Tamper-proof, permanent fleet tracking
- Driver behaviour scoring based on vehicle data
- Integration with fleet management platforms requiring hardwired I/O
- Tracking large fleets where manual recharging is impractical
10. TK905 vs Hardwired Trackers: When to Upgrade
| Feature | TK905 | Hardwired (e.g. FMC920) |
|---|---|---|
| Installation | None (magnetic) | Professional required |
| Power source | Internal battery | Vehicle power (always on) |
| CAN bus data | No | Yes |
| Tamper resistance | Low | High |
| Real-time tracking | Limited by battery | Unlimited |
| Fleet scalability | Low (recharging) | High |
| Best for | Assets, small fleets | Active fleet vehicles |
| Cost | Lower upfront | Higher (device + install) |
Our recommendation: use the TK905 for assets and equipment, and hardwired trackers for active fleet vehicles. Many of our NSW clients run both in parallel — FMC920s on their utes and vans, TK905s on their trailers and generators.

12. FAQ
How long does the TK905 battery last with real-time tracking?
At 30-second tracking intervals, expect 7–14 days of battery life. For longer battery life, increase the tracking interval to 5 minutes (30–45 days) or 1 hour (60–90 days). The right balance depends on your tracking requirements.
Is the TK905 waterproof?
Yes. The TK905 carries an IP67 rating, meaning it's fully dustproof and water-resistant to 1 metre immersion for 30 minutes. It's suitable for Australian outdoor conditions including rain, dust, and mud.
Can the TK905 track in remote areas of NSW?
The TK905 relies on 4G LTE (with 2G fallback). Coverage in remote NSW can be limited. For reliable tracking in remote areas, consider a tracker with satellite backup capability. In metro Sydney and major regional centres, coverage is generally excellent.
Can I track my trailer with a TK905?
Yes — this is one of the TK905's best use cases. The magnetic mount attaches easily to trailer chassis, the IP67 rating handles outdoor exposure, and the long battery life means infrequent recharging. Many NSW transport operators use TK905s on trailers alongside hardwired trackers on prime movers.
Does the TK905 work for theft recovery in Sydney?
Yes. The covert form factor, motion detection alerts, and real-time tracking make it effective for theft deterrence and recovery. NSW Police can use GPS data to assist with vehicle recovery when a theft report is filed. Covert placement (e.g., inside a wheel arch or chassis cavity) makes it harder for thieves to locate and remove.
How much does the TK905 cost in Australia?
Pricing varies by supplier and platform subscription. Contact Techtonika Autolink for current pricing, including hardware and platform options suited to your fleet size and tracking requirements.
13. Our Verdict
The TK905 is a genuine workhorse for asset and covert tracking in Australia. Its combination of 4G LTE, IP67 durability, long battery life, and zero-installation deployment makes it one of the most versatile magnetic GPS trackers available.
For active fleet vehicle tracking where you need real-time data, CAN bus integration, and tamper-proof permanence — step up to a hardwired solution. But for trailers, equipment, rental vehicles, and small business use cases across Sydney and NSW, the TK905 delivers strong value.
Rating: 4.2 / 5 for its intended use case.
