Baseus EnerFill Crams 100W of USB-C Across 3 Ports Into a Compact GaN Wall Charger at $22

What it is

The Baseus EnerFill 100W 3-Port USB-C GaN Wall Charger is a compact wall charger with two USB-C PD 3.0 ports supporting up to 100W single-port output (or 65W + 30W split across both when both USB-C ports are used), plus one USB-A port. Gallium Nitride (GaN) semiconductor construction makes the charger roughly 30-40% smaller than equivalent silicon-based chargers at the same wattage. Folding prongs, international voltage support (100-240V), and active cooling are standard.

Pricing is $22 on Amazon with the Y9FY coupon (MSRP $50), a 56% discount per 9to5toys.

What's interesting

100W single-port USB-C PD output is enough to fast-charge a MacBook Pro 14-inch at full speed, a 13-inch MacBook Air at maximum rate, and every current-generation iPad Pro. For a universal laptop charger, the single-port 100W capability eliminates the need to carry the manufacturer's bundled charger.

GaN construction is the technology enabling 100W in a compact form. Traditional silicon chargers at 100W run at roughly the size of a Mac mini; GaN shrinks the same output to roughly the size of an iPhone in thickness. For travel, this is the difference between packing a dedicated charger brick and slipping the Baseus into a laptop sleeve.

Multi-port use shares wattage intelligently. When one USB-C port is used alone, it delivers the full 100W. When both USB-C ports are used, the allocation becomes 65W + 30W, enough for a MacBook Pro plus an iPhone on full-speed fast-charge. For travelers charging multiple devices overnight, the share logic works cleanly.

The USB-A port is a nice-to-have for older devices (Kindle, Bluetooth accessories, older Androids) that still use USB-A cables. The USB-A port pulls 18W at maximum, which is slower than USB-C PD but adequate for legacy accessories.

At $22 sale price, Baseus undercuts Anker's 65W Nano II ($45) and Apple's 70W USB-C Power Adapter ($59) by a significant margin. For students, apartment dwellers, and travelers, the value is meaningful.

What's missing or unverified

100W single-port only works with one USB-C port active. If both USB-C ports are occupied, the single port caps at 65W, which is still plenty for most USB-C laptops but not optimal for a MacBook Pro 16-inch under sustained load (that laptop draws up to 140W).

Baseus is a Chinese-manufactured charger brand with solid but not premier reliability reputation. Anker, Belkin, and Apple chargers have more rigorous warranty service and safety certification. Baseus is FCC-certified and CE-marked for EU, but long-term reliability data is thinner.

At 100W peak output, the charger runs warm under sustained full-load operation. 9to5toys noted active cooling handles sustained 60W+ loads without throttling, but the housing does get visibly warm during 100W charging.

The coupon-based $22 pricing is a recurring promo rather than a permanent price. New buyers should verify coupon availability at purchase time.

No USB-C to USB-A adapter included. Users with older peripheral cables need to supply their own adapters.

Who it's for

MacBook Air and MacBook Pro 13-14 inch users who want a single travel charger replacing the bundled Apple brick. iPhone 15/16 users fast-charging their phones daily. Travelers carrying laptop + phone + tablet who need one charger for all three devices.

Not for: MacBook Pro 16-inch users under sustained load (the 100W cap is below the laptop's 140W maximum draw), Apple-ecosystem loyalists who want Apple's own branded charger, or commercial-use buyers needing rigorous safety certifications.

Verdict

The Baseus EnerFill 100W GaN Charger at $22 is the best-value universal charger for laptop-and-phone travel use. 100W output, three ports, GaN compactness, and international voltage support hit a strong spec sheet at a third of Apple's equivalent charger price. Against the Anker 65W Nano II at $45 and Apple 70W USB-C Power Adapter at $59, Baseus wins dramatically on price and port count; it loses slightly on long-term reliability reputation. For most buyers at this price point, the trade is worth it.
