For an owned or authorized vehicle, a magnetic GPS tracker is the more portable installation format: it does not require a permanent vehicle wiring job, but its battery, mounting strength and placement still need maintenance and testing.
A wired GPS tracker is the more permanent format: it draws from vehicle power and can support a fixed fleet installation, but the exact harness, power input, optional accessories and installation work have to match the tracker and vehicle.
Neither format automatically answers the SIM, platform, monthly-service or reporting-frequency questions. Those are separate decisions.

What changes when you choose a magnetic GPS tracker?
A magnetic tracker moves installation work away from the vehicle wiring and toward battery, mounting and placement checks.

Real QZT TK905 scene. The current page lists magnetic vehicle or asset mounting and tells buyers to confirm final mounting strength on a sample.
Current QZT magnetic examples include:
– TK905: magnetic GPS tracker; current page lists 90 × 72 × 22mm and says final magnetic mounting strength should be confirmed on a sample.
– TK913: smaller magnetic / portable format; current page lists 54 × 35 × 22mm and tells buyers to confirm the placement setup and runtime for the project.
– G50: 4G magnetic tracker with several body-size versions; current page tells buyers to confirm the selected version, SIM/network requirement, app platform, mounting strength and expected battery runtime.
The installation advantage is clear: you do not need to route a permanent power harness into the vehicle for these battery-powered formats.
The maintenance tradeoff is equally important. A portable tracker has to remain charged and physically secure enough for the intended use. The QZT GPS battery-life guide explains why reporting interval, signal conditions, movement behavior, temperature and firmware can change runtime. Do not turn a battery-body size into a fixed number of days without a same-condition sample test.
For a magnetic sample, record:
– exact model and body version;
– mounting surface used for the authorized test;
– whether the unit remains secure under the permitted test conditions;
– GPS and cellular performance at that position;
– reporting schedule;
– charging routine and actual runtime;
– SIM / platform configuration.
What changes when you choose a wired GPS tracker?
A wired tracker replaces routine recharging with a vehicle-power installation, but it adds harness and electrical work.

Real QZT N70 installation scene. Current QZT guidance calls for a qualified installer for power, ACC and optional relay wiring.
Current QZT wired examples include:
– N70: current page lists DC 9–90V input, a four-pin hardwired harness, ACC status and optional relay support.
– N80: current page lists DC 9–90V and adds external microphone and SOS interfaces, with optional relay support.
“Wired” does not mean every tracker shares one color code or connector. N70 and N80 already show why the exact package matters.
Before a wired installation, confirm:
– tracker model / hardware revision;
– documented input-voltage range;
– supplied harness and connector;
– power / ground / ACC assignments from the exact manual;
– optional relay, SOS or audio requirements;
– SIM and cellular bands;
– platform/account setup;
– qualified installer and vehicle service information.
For the detailed pre-install checklist, use the QZT wired GPS tracker installation guide. It intentionally avoids a generic wiring diagram.
How do current QZT magnetic and wired examples differ?
The current product pages are enough to compare the installation architecture, but they are not a same-condition performance test.

Real QZT TK913 product photograph. The table compares current public product-page facts, not a ranking of which tracker is “best.”
| QZT example | Installation / power format | What current page establishes | What still needs sample verification |
|---|---|---|---|
| TK905 | Magnetic / battery-powered format | Magnetic vehicle or asset mounting; SIM/network plan and app/server setup to confirm | Mounting strength, runtime, signal at the chosen position |
| TK913 | Compact magnetic / portable format | Smaller 54 × 35 × 22mm body; SIM/network plan to confirm | Runtime, mounting/placement, app/server behavior |
| G50 | 4G magnetic / battery-powered format | Several body-size versions; 4G tracker format | Selected battery/body version, mounting strength, runtime, SIM/platform |
| N70 | Hardwired / vehicle power | DC 9–90V; four-pin harness; ACC; optional relay; 4G platform setup | Exact harness, installation, SIM/bands, alerts, recovery |
| N80 | Hardwired / vehicle power | DC 9–90V; SOS + external microphone; optional relay | Exact accessory set, privacy/consent for audio, installation and service |
This table does non say TK905, TK913 or G50 has a particular number of battery days. The current pages do not publish a same-condition runtime comparison.
It also does not say N70 or N80 is “maintenance free.” A fixed tracker still depends on vehicle power, network service, platform/account access and a correct installation.
Which placement and signal checks matter for a magnetic tracker?
A magnet holding the housing in place is only one part of the installation.
![]()
Real QZT G50 product photograph. Placement still has to be checked for mounting security, GNSS/cellular service and environmental exposure.
On an authorized sample vehicle, check:
1. Mounting surface: Is the surface suitable for the magnet and allowed by the vehicle/project owner?
2. Conservazione: Does the tracker remain secure under the project’s permitted road/vibration test?
3. Signal: Can the unit obtain a useful GNSS fix and register to the cellular service from that position?
4. Ambiente: Is the housing protected appropriately from heat, water, impact and abrasion for that exact model?
5. Serviceability: Can authorized staff inspect, recharge and remove the device when required?
6. Account/device identity: Does the platform show the correct tracker after it is moved or reinstalled?
Do not assume that a stronger magnet fixes a poor radio position, or that a good radio position proves the mount is secure.
Avoid copying “best hidden mounting locations” from another vehicle or product. The practical requirement is a secure, authorized and tested position, not maximum concealment.
How do maintenance and total cost differ?
The form factor changes where the maintenance work happens; it does not remove the other service layers.

For a magnetic tracker, plan for:
– charging or battery replacement if applicable;
– periodic physical inspection;
– rechecking the mount after removal/reinstallation;
– maintaining SIM / platform service;
– checking runtime after reporting-frequency or firmware changes.
For a wired tracker, plan for:
– qualified installation;
– harness and connector inspection;
– vehicle-power and ACC behavior;
– optional accessory support;
– SIM / platform service;
– service records if the tracker is removed or the vehicle changes.
For recurring costs, use GPS Trackers With No Monthly Fee: What Costs Still Apply?. It separates hardware, SIM/data, platform/server, installation and support.
For battery runtime, use Quanto dura la batteria di un localizzatore GPS con il tuo intervallo di segnalazione?. That owner handles reporting interval, signal quality, movement and temperature rather than repeating generic “days” here.
The comparison is therefore not:
> magnetic = free / wired = expensive
It is:
> magnetic shifts effort toward battery and portable mounting; wired shifts effort toward professional installation and vehicle-power integration.
What should you sample before choosing the format?
Do not approve a fleet or resale SKU from the product shape alone.

If the deployment needs a permanently powered tracker and the vehicle can be professionally modified, a wired format may fit the operating model better.
If the deployment needs a portable unit that can be removed and recharged without a wiring job, a magnetic format may fit better.
The sample decides whether that theoretical advantage survives the actual vehicle, network, reporting schedule and operating process.
Domande frequenti
Is a magnetic GPS tracker better than a wired tracker for a car?
Not universally. A magnetic tracker is easier to deploy without permanent wiring and can be more portable. A wired tracker uses vehicle power and is better suited to a fixed installation when the vehicle owner authorizes professional wiring. Choose by operating requirements, then sample-test the exact model.
Does a magnetic GPS tracker need a SIM or subscription?
For current QZT real-time examples, the product pages tell buyers to confirm the SIM/network plan and app/server setup. The magnetic mount does not remove the communication path. See the QZT no-monthly-fee GPS guide for the cost layers.
How long does a magnetic GPS tracker battery last?
There is no useful model-independent answer. Current TK905, TK913 and G50 pages do not publish a same-condition runtime comparison. Test the exact reporting schedule and signal conditions; the QZT battery-life guide covers those variables.
Can I move one magnetic tracker between vehicles?
Only on vehicles/assets you own or are authorized to track. If you move the unit, recheck physical retention, GNSS/cellular performance, device/account identity and the operating process for the new placement.
Does a hardwired GPS tracker still need a SIM?
For current QZT N70/N80 real-time 4G examples, yes: the public pages tell buyers to test SIM/network and platform setup. The vehicle-power wire does not replace the cellular communication path.
Does hardwired mean I can use any vehicle wire?
No. Use the exact tracker manual/harness documentation and the vehicle manufacturer’s service information. N70/N80 list a wide input range, but that does not identify the correct connection point in every vehicle.
The decision rule is simple: choose magnetic when portable, non-permanent installation fits the operating process and you can maintain the battery; choose wired when an authorized permanent installation and vehicle power fit the project. Then prove the choice on a sample.
