Cheapest per-slot, full power-split published
Enterprise-grade build, potting compound thermal design
Most laptops per socket — shared charging island
Single point of failure: 1 dead unit = 4–5 desks down. Keep 5–10% spares.
Lower is better. Calculated as lowest HK retail price ÷ conservative laptop slots (≥65W).

PD 3.1 with 140W C1, 2m AC cord — but expensive per slot
Premium brand, CEW insurance — but 2× the cost of GS200
Wall-plug form factor, clear port ratings — HK$219/slot
Only charger in this roundup with a complete power-split table published on the product page. At 2-port: 100W + 100W; 3-port: 100W + 65W + 30W; 4-port: the extra ports drop to 5V/2.4A. BS1363 certified with IEC 62368-1 compliance, product liability insurance, and 1-year warranty. For fleet deployment, this is the "no-surprises" pick.
ChargerLAB teardown shows PFC + AHB architecture with potting compound for heat dissipation — the kind of build quality you see in enterprise-grade PSUs. Price.com.hk user rating: 5.0. The trade-off: power-split details require scanning a QR code in the manual, and the public product page only says "smart distribution." For mission-critical desks, this is the insurance pick.
Macworld review confirms 1×140W + 4×60W simultaneous output, staying cool under load. 60W is enough to sustain most laptops during normal work. But this is a single point of failure — one dead unit takes out 5 desks. Best deployed as shared charging islands in meeting rooms, not per-desk. The 100W ports may drop to 60W in certain multi-port configurations.
This is the #1 trap in GaN charger marketing. A "200W 8-port" charger sounds like it powers 8 laptops — in reality, most have only 1–2 ports at ≥65W, with the rest at 15–30W (phone/tablet territory). Always check the power-split table for simultaneous multi-port output, not the single-port max. If no table is published, assume the worst.
For a 200-MacBook office: 100× GS200 (HK$34,800 total, 100 sockets) covers every desk at ≥65W. Add 10× X759 (HK$9,980) for meeting rooms and shared areas — that's 50 more "maintenance slots" at 60W each. Total: HK$44,780 for 200 desks + 50 shared slots. Keep 5–10 spare GS200 units distributed per floor.
