If you’ve got a trailer with faulty lights, the last thing you need is to waste time tracking down a tractor unit just to test it. That’s exactly the kind of frustration the Jaltest PTE – Portable Trailer E‑Supply – is designed to solve. This clever, pocket‑sized box lets you power up a trailer’s electrics on the spot — no truck required — so you can quickly check lights, CAN signals and indicators, wherever you are.
What is the Jaltest PTE – Portable Trailer E‑Supply?
The Jaltest PTE is a portable electrical test unit designed by Jaltest and available to buy at Eclipse. Its core objective: to mimic a tractor unit’s electrical output so you can power up trailer lights, CAN signals and indicator circuits without hooking up to a truck.
This clever device offers two operation modes, selectable via an intuitive LED interface—one mode replicates standard trailer wiring as if it were attached to a tractor unit; the other is tailored for direct trailer testing. The result: instant signal verification and substantial savings in diagnostic time.
What’s Included in the PTE Package?
The Jaltest PTE package doesn’t scrimp – you get everything needed in one box, including:
- Jaltest Portable Trailer E‑Supply unit
- 12/24 V charger (to keep the tool powered and portable)
- Serpentine adapters for:
- 15‑terminal A 7S/7N truck
- 7‑terminal 24 V Type‑N ISO 1185
- 7‑terminal 24 V Type‑S ISO 3731
- 7‑pin EBS ISO 7638
These adapters ensure compatibility with virtually all trailer wiring standards in Europe – no fumbling with loose cables or jury‑rigged adapters.
Key Benefits of the Jaltest PTE
1. Fully Portable
It eliminates the need for a tractor unit during testing, allowing technicians to diagnose trailer electrics anywhere—in the yard, on the roadside or in the workshop.
2. Speed and Efficiency
With LED status indicators for every function – lights, indicators, CAN – you get immediate pass/fail data. No need to trace wires manually or guess signal output.
3. Versatile Power Modes
Choose between standard or test‑mode operation depending on your diagnostic needs, giving you flexibility across a wide range of trailer types and configurations.
4. Rugged & Ready
Housed in a durable casing with a universal charger, the unit is built for daily use. It’s road‑worthy and workshop‑tough—ready for the most demanding fleets.
5. Saves Labour Costs
By enabling faster fault identification, it dramatically reduces vehicle off-road (VOR) time and labour expenses. The tool’s speed and accuracy pay for themselves in no time.
6. Perfect Companion to Full Jaltest Diagnostics
Designed to complement the flagship Jaltest diagnostic tool, it forms part of a powerful electrical fault‑finding ecosystem for trailers. When combined, they offer unbeatable diagnostics capability.
Special Offer: Just £745.00 ex VAT
For a limited time, Eclipse is offering the complete Jaltest PTE package for only £745.00 ex VAT, reduced from £1,195.00. This £450 saving (£539 including VAT) on advanced diagnostic tech is a cost-effective step-up for any workshop or fleet.
Who Should Invest in the PTE Package?
- Truck and trailer fleets: Faster turnaround, less trailer downtime—an immediate ROI.
- Independent workshops/garages: Offers a premium diagnostic tool at a fraction of the price.
- Rental/haulage companies: Ideal for ensuring trailers are always road-ready.

Comparison: Package vs. Unit‑Only
Eclipse also provides an option to buy just the PTE unit without accessories: the Portable Trailer E‑Supply Unit‑Only. This may suit those who already own chargers/adapters, but for most users, the full Package is the smarter, more complete investment.
