MOKiN TrueGround Review: The Class 1 GaN Charger That Stops the Laptop Tingle — Tested
Quick Verdict — MOKiN TrueGround is the world's first compact Class 1 grounded GaN charger. In testing, it reduces leakage current from ~166 µA (typical Class 2 charger at MY 240V) to ~2 µA — the laptop tingle disappears on first use. GaN charging speed is on par with comparable 2-prong models. The 3-pin plug fits every Malaysian and Singaporean wall socket natively. Available from 20W to 140W. If you feel a tingle or buzz while charging, this is the fix.
Built to Solve One Specific Problem — and It Does
MOKiN TrueGround is purpose-built for users who feel a faint tingle, buzz, or mild shock when touching their laptop while it charges. If you own a MacBook, Dell XPS, HP Spectre, Lenovo ThinkPad, Asus ZenBook, or Microsoft Surface Laptop — or a metal-body iPhone or Samsung Galaxy — this review is for you.
A standard 2-prong Class 2 GaN charger at Malaysia's 240V mains produces approximately 166 µA of leakage current at the device chassis. This is within the IEC 62368-1 safety limit of 250 µA, but it is clearly perceptible to most users on tiled floors or when grounded through contact with another surface. MOKiN TrueGround is for users who want to stop tolerating it — not work around it.
This is not the charger for someone whose sole concern is compact size or international travel plug compatibility. TrueGround uses a 3-pin plug that is native to Malaysian and Singaporean BS 1363 wall sockets — which is exactly the right design for the local market, and the feature that makes earth grounding possible.
Does It Actually Eliminate the Tingle? — ~166 µA to ~2 µA, Measured
A standard 2-prong Class 2 GaN charger at Malaysia's 240V mains produces approximately 166 µA of leakage current at the device chassis. This is within the IEC 62368-1 safety limit of 250 µA, but it is clearly perceptible to most users on tiled floors or when grounded — particularly users on bare feet, with damp hands, or in contact with a metal desk.
With MOKiN TrueGround connected to the same 240V wall socket and the same laptop, measured leakage current at the chassis: ~2 µA.
Test result: ~98% leakage current reduction. TrueGround's earth pin provides a direct, low-resistance path for Y-capacitor leakage current to flow to the building's ground before it reaches the laptop's chassis. From the user's perspective, the tingle is gone — not reduced, not improved. Gone.
This result is consistent across all five wattage models. The leakage current reduction is a function of the Class 1 architecture — the earth pin and internal earth connection — not the wattage or GaN topology. A 20W TrueGround produces ~2 µA. A 140W TrueGround produces ~2 µA. The engineering is the same.
Class 1 Grounded — IEC 62368-1 Architecture
Which TrueGround Charger Is Right for You?
The correct wattage depends on your primary device and workflow. Every model shares the same Class 1 grounded GaN architecture and measures ~2 µA leakage current regardless of wattage.
- 20W — Phone-primary users. Fast-charges any current iPhone and Samsung Galaxy flagship via USB-C PD. Best for users who only need to charge a phone and want the smallest footprint with earth protection.
- 33W — Phones and tablets. Handles an iPad, Android tablet, or larger-battery phones at good speed. Suitable as a desktop charger for mobile-only users.
- 45W — Light laptops and phones. The minimum recommended wattage for MacBook Air (M2/M3) and Dell XPS 13. Handles both a phone and a light laptop across alternating sessions.
- 65W — ★ Most Popular — MacBook Pro 14", Dell XPS 15, ThinkPad X1 Carbon, HP Spectre x360 13", Asus ZenBook 14. The most versatile single-port option for laptop users.
- 140W — Pro laptops and multi-device users. Full 140W PD 3.1 delivery. USB-C and USB-A ports. Powers a MacBook Pro 16" and a phone simultaneously. The correct choice for power users who need one charger to do everything.
TrueGround FAQ
What exactly is a Class 1 charger, and why does it matter?
What exactly is a Class 1 charger, and why does it matter?
Under IEC 62368-1, electrical devices are classified by how they manage fault energy. A Class 2 device (the standard 2-prong charger) relies on double or reinforced insulation as its only protection — there is no earth connection. A Class 1 device includes a protective earth (ground) connection as an additional safety layer. For chargers, this means the third pin connects the charger's internal earth path to the building's ground. When Y-capacitors — necessary components in all switch-mode power supplies — pass a small leakage current, Class 1 design routes that current to earth rather than through the device chassis and into the user. The result is the elimination of the tingle sensation most laptop users in Malaysia and Singapore experience.
Is the laptop tingle actually dangerous, or just uncomfortable?
Is the laptop tingle actually dangerous, or just uncomfortable?
Leakage current within the IEC 62368-1 limit of 250 µA is considered safe for a healthy adult under normal conditions. A typical Class 2 GaN charger at Malaysia's 240V mains produces approximately 166 µA — within the limit, but clearly perceptible to most users, particularly on tiled floors or when barefoot. The distinction MOKiN draws is between 'within safety limits' and 'acceptable user experience'. The sensation is also stronger for users with lower body resistance (damp skin, bare feet, contact with a grounded metal surface). MOKiN TrueGround reduces measured leakage to ~2 µA — effectively eliminating the sensation and the leakage current path to the user entirely.
Will TrueGround charge my laptop slower than my current charger?
Will TrueGround charge my laptop slower than my current charger?
No. TrueGround uses Gallium Nitride (GaN) switching technology across all five models. The Class 1 grounded architecture adds no charging speed penalty. Real-world benchmarks show charging speeds that match comparable 2-prong GaN chargers of the same wattage. The 65W model charges a MacBook Pro 14" from 0–100% in approximately 2 hours; the 45W model charges a MacBook Air (M2/M3) from 0–80% in approximately 90 minutes. All models support USB Power Delivery (USB PD) and are compatible with current MacBook, Dell, HP, Lenovo, Asus, and Microsoft laptop lines, as well as iPhone and Samsung Galaxy devices.
Does TrueGround fit standard Malaysian and Singaporean wall sockets?
Does TrueGround fit standard Malaysian and Singaporean wall sockets?
Yes — by design. TrueGround uses a 3-pin plug that is native to the BS 1363 wall sockets used in Malaysia and Singapore. Every wall socket, extension lead, and power strip in the region has a ground terminal. There is no adapter required and no practical inconvenience compared to a 2-prong charger. The 65W and 140W models feature a foldable plug design for easier packing. The 3-pin plug is also what makes earth grounding possible — it is not a design compromise but the core engineering requirement of the product.
Which TrueGround wattage should I buy for a MacBook Pro?
Which TrueGround wattage should I buy for a MacBook Pro?
For a MacBook Pro 14", the 65W model is the recommended choice — it charges from 0–100% in approximately 2 hours and is the most popular TrueGround model. For a MacBook Pro 16", the 65W model powers the laptop at near-full speed; the 140W model is the correct choice if you also need to charge a second device simultaneously or want maximum charge rate. For a MacBook Air (M2/M3), the 45W model is the minimum recommended wattage, charging 0–80% in approximately 90 minutes.
Does TrueGround work for phones — not just laptops?
Does TrueGround work for phones — not just laptops?
Yes. The leakage current tingle is also experienced by users of metal-body smartphones — including iPhone and Samsung Galaxy handsets — when charging with a 2-prong adapter. TrueGround eliminates the same root cause for phone users. The 20W model is designed for phone-primary users: it fast-charges any current iPhone and Samsung Galaxy flagship via USB-C PD, from 0–50% in approximately 30 minutes. The 33W model is appropriate for users who also charge tablets. Both models measure ~2 µA leakage current — the same reduction as the laptop-focused models.
