2 Best Small GPS Trackers: Reviewed and Ranked By Our Experts

Below is a closer look at how each device performs on size, battery life and tracking capability, along with a note on Thatcham-approved alternatives for vehicle-specific insurance needs.

1. GPSBob Yabby Battery 4G GPS Tracker

The GPSBob Yabby takes the top spot because it solves the single biggest limitation of most small trackers: battery life. At 90 x 45 x 30mm, it's genuinely compact enough to attach to luggage, a pet collar or tuck away in a vehicle, yet it can run for up to five years on a single set of batteries or charge when set to one update a day, which no competitor on this list comes close to matching.

Compared with the Tracki 4G, which needs charging every few days, the Yabby is built for genuinely long-term, low-maintenance tracking rather than short bursts of real-time monitoring.

It does offer faster update modes too, cycling through 24 updates a day for around 1.5 years or movement-based tracking for up to 2 years plus the option to be set to track on motion, giving users flexibility depending on whether they prioritise battery longevity or tracking frequency. Its £3.99 monthly plan with no lock-in also undercuts Tracki's £19.95 monthly rate significantly, while prepay options offer further savings for those happy to commit longer term.

Rating: 4.8/5, based on strong Trustpilot and Google reviews.

Pricing: £89.99 for the device, plus a choice of subscription plans:

• £3.99 pay monthly, cancel anytime, no commitment
• £135.48 prepay for 1 year, saving £2.39 versus monthly
• £176.17 prepay for 2 years, saving £9.58 versus monthly
• £212.08 prepay for 3 years, saving £21.55 versus monthly
• £243.21 prepay for 4 years, saving £38.30 versus monthly
• £269.54 prepay for 5 years, saving £59.85 versus monthly

Key features:

• Up to 5 years battery life on one update a day
• 4G connectivity with real-time location updates
• Compact, water and dust resistant design
• Remote history tracking to review past movement
• Flexible tracking modes including movement-based tracking

2. Tracki 4G

The Tracki 4G is one of the most recognisable names in the small tracker space, largely thanks to its genuinely tiny footprint and magnetic mounting, which makes it easy to hide underneath a vehicle or slip into a bag without anyone noticing. It uses GPS, Bluetooth and 4G LTE connectivity, giving it solid coverage across Britain and worldwide.

Where it falls behind the Yabby is battery life. Tracki's average battery lasts just 3.5 days in real-time mode, stretching to 60 days in battery-saving mode at best, which means far more frequent charging than the Yabby's multi-year runtime. Its subscription is also considerably pricier on a monthly basis, though the prepay options for 6 months, 1 or 2 years bring the effective cost down somewhat for longer-term users.

Rating: 4.3/5, reflecting strong portability but limited by shorter battery life.

Pricing: £9.88 for the device, plus a choice of subscription plans:

• £19.95 pay monthly, cancel anytime
• £99.60 prepay for 6 months
• £167.40 prepay for 1 year
• £239.00 prepay for 2 years

Key features:

• Portable, waterproof and magnetic design
• GPS, Bluetooth and 4G LTE connectivity
• Compact 45 x 40 x 18mm size, weighing 36g
• Geo-fence, movement and speed alerts via app
• Suitable for vehicles, trailers, boats and asset monitoring

How to Choose the Best Small GPS Tracker

• Decide what you're tracking. Personal items like luggage or pets suit compact battery trackers, while vehicles may need Thatcham-approved insurance compliance instead.
• Prioritise battery life if you want low maintenance. Trackers with multi-year battery life need far less attention than those requiring charging every few days.
• Check the subscription cost over time. A cheaper device with a high monthly fee can end up costing more than a pricier tracker with better long-term rates.
• Consider update frequency versus battery longevity. More frequent updates drain the battery faster, so choose a mode that matches your priorities.
• Look for water and dust resistance. This matters most for trackers placed outdoors, on vehicles, or attached to pets.
• Confirm connectivity type. 4G LTE trackers generally offer wider and more reliable coverage than older 2G or 3G devices.
• Read genuine customer reviews. Ratings above 4.5/5 on Trustpilot or Google are a good sign of reliable performance and support.

FAQs

How small can a GPS tracker be while still working reliably?

Many compact trackers measure under 100mm and still deliver accurate, real-time location data thanks to modern 4G and GPS chip miniaturisation.

Do small GPS trackers work without a SIM card?

No, most small GPS trackers require an embedded SIM or subscription to transmit location data over mobile networks.

Can a small GPS tracker be used to monitor a pet?

Yes, provided it's lightweight, weatherproof and has a suitable attachment method such as a collar clip.

How often should a GPS tracker update its location?

It depends on the use case. Frequent updates suit real-time vehicle tracking, while daily updates are usually sufficient for long-term asset monitoring.

Is a battery-powered tracker less reliable than a wired one?

Not necessarily. Modern battery trackers with multi-year lifespans can be just as reliable, though wired trackers avoid the need for any battery management at all.
