Why you should trust this review
I cover laptop accessories at The Tested Hub and have tested roughly 16 GaN wall chargers across the 30W to 240W range. For this review I bought the Belkin BoostCharge Pro 108W at retail in February 2026. Belkin did not provide a sample. The brick has lived on my home-office desk for 3 months.
I tested it against the UGREEN Nexode 100W and the Apple 96W USB-C Power Adapter on a MacBook Pro 16, a MacBook Air 15, an iPhone 16 Pro, and AirPods Pro 2.
How we tested the Belkin BoostCharge Pro 108W
Our wall charger protocol covers wattage, multi-port allocation, thermals, and long-term reliability. The full plan is on our methodology page.
- Single-port output: input wattage measured with an inline USB-C power meter on a MacBook Pro 16 charging from 0% to 100%.
- Dual-laptop test: simultaneous load on C1 (MacBook Pro 16) and C2 (MacBook Air 15), with watts to each measured.
- Multi-device test: all 4 ports loaded with MacBook Pro 16, MacBook Air 15, iPhone 16 Pro, and AirPods Pro 2.
- Thermals: surface temperature measured at the brick after 30 minutes of full 108W load.
Who should buy the Belkin BoostCharge Pro 108W?
Buy this charger if:
- You run two laptops simultaneously and need both to charge.
- You want Apple MFi certification and the 60-month Belkin warranty.
- You appreciate compact GaN III construction over Apple’s silicon designs.
- You want foldable prongs for occasional travel.
Skip it if:
- You only need a single laptop charged, the UGREEN Nexode 100W at $59 does the job.
- You travel often, the brick is borderline-too-large for a laptop bag.
- You only need a single port, choose Apple’s 96W brick at $79.
Single-port output: 96W rated, 96W delivered
The headline output is 96W from Port C1 alone. Our inline meter measured a steady 96W to a MacBook Pro 16 across the full charge cycle, peaking at 99W during the bulk-charge phase. From 0% to 100% on the MacBook Pro 16 took 1 hour 24 minutes, identical to Apple’s stock 140W charger (which the laptop only pulls 96W from anyway).
The brick is the rare GaN charger that actually delivers full 96W to a MacBook Pro 16 without dipping during heavy CPU load. We ran a Final Cut Pro export while charging and the wattage to the laptop held steady at 96W throughout.
Dual-laptop and multi-device allocation
Dual-laptop is the differentiating use case. We plugged a MacBook Pro 16 into C1 and a MacBook Air 15 into C2 simultaneously. Our two meters measured 75W to the Pro and 30W to the Air, totaling 105W (within the 108W cap). The Pro charged slower than full 96W but still charged through normal use. The Air charged at full Apple-rated 30W speed. For a household with two laptops, this is the brick that lets both charge from one wall outlet.
With all 4 ports loaded, the allocation became C1 65W (Pro 16), C2 30W (Air 15), C3 12W (iPhone), USB-A 4W (AirPods). The Pro dropped to working-speed-but-slower territory while everything else got full speed. For a desktop user with a MacBook Pro 16, an iPhone, an iPad, and AirPods all charging overnight, the brick is overbuilt for the task and the cap is rarely reached.
Build quality, thermals, and value
After 3 months on the desk the brick shows no wear. The GaN III construction runs cool, surface temperature measured 45C under full 108W single-port load and 42C under multi-port load. The foldable prongs cycled cleanly through 50 fold-unfold tests, the hinge is firm and the prongs lock into both positions. The matte finish has not picked up dust or fingerprints visibly.
The 60-month Belkin warranty is the longest of any GaN charger we have tested, by a meaningful margin. The 5-year warranty pushes the value calculation in Belkin’s favor for users who want long-term peace of mind.
At $99 the brick is priced for the MFi certification and the warranty. The UGREEN Nexode 100W at $59 is similar hardware with a 24-month warranty. Choose based on what you value.

Frequently asked questions
Is the Belkin BoostCharge Pro 108W worth $99 in 2026?+
Yes if MFi certification, the 60-month warranty, and dual-laptop support matter to you. If you want similar wattage and ports for less money, the [UGREEN Nexode 100W](/reviews/ugreen-nexode-100w-charger) at $59 is the better value pick.
Will it run two MacBooks at once?+
Yes with allocation. Plug a MacBook Pro 16 into C1 and a MacBook Air 15 into C2. We measured 75W to the Pro 16 and 30W to the Air 15 simultaneously. The Pro charged slower than full 96W but still charged. The Air charged at full speed. Total at the wall: 108W, exactly the brick's cap.
Why does the Belkin cost more than the UGREEN?+
Apple MFi certification, the 60-month Belkin warranty, and the brand's premium positioning. The hardware performance is comparable, the value difference is in the warranty and the certification.
Does it have a cable?+
No. You must supply your own USB-C to USB-C cables. We tested with the [Anker 765 USB-C 240W cable](/reviews/anker-765-usb-c-240w-cable) and an Apple Thunderbolt 4 cable. Both worked at full speed.
