Anker Prime 100W GaN Wall Charger (3 Ports), model A2343. Amazon ASIN B0C4DGBHY2.

A MacBook travel kit is usually two stories: the hub that puts ports back on the laptop, and the wall brick that keeps the laptop charging while that hub is busy. I already wrote the hub side the Anker 555 USB-C Hub is the one I would keep on a normal Mac desk. This note is the brick that plugs into that hub’s PD-in port, or straight into the Mac when you leave the hub at home.

The charger I would look at for that job is the Anker Prime 100W GaN Wall Charger (3 Ports) model A2343, Amazon ASIN B0C4DGBHY2. Price band when I checked recent deal writeups and older list mentions: roughly $45–$85 depending on the day. Confirm the live Amazon price; it moves. This is a buying note from a Mac engineer in Jakarta, not a fake six-month lab. Specs below are from Ankers product page and the Amazon listing for that ASIN.

Naming check: people still call compact Anker GaN bricks “737 GaNPrime.” The Anker 737 Charger (GaNPrime 120W) is a different product (model A2148, 120W total). B0C4DGBHY2 / A2343 is the Prime 100W three-port wall charger. Buy the ASIN, not the nostalgia nickname.

Why this particular charger

Headline facts from Anker / the Amazon listing:

• 100W total GaN wall charger in a compact body Anker quotes as about 1.7 × 1.5 × 2.3 in (44 × 39 × 60.5 mm) and about 6.4 oz / 183 g.
• 3 ports: two USB-C + one USB-A. Either USB-C can do up to 100W alone; USB-A up to 22.5W.
• Multi-port split (Anker’s table): USB-C + USB-C ≈ 65W + 35W; USB-C + USB-A ≈ 76W + 22.5W; all three ≈ 46W + 30W + 22.5W. Total still caps at 100W.
• GaNPrime branding on the listing, with Anker’s ActiveShield 2.0 temperature-monitoring safety story.
• Anker markets it as about 43% smaller than Apples original 96W MacBook charger — useful for a pouch, not a magic claim.
• US plug is the foldable type on this SKU. Box contents on Anker/Amazon: charger + welcome guide (standard listing does not promise a cable). Warranty language on Anker’s page / Amazon bullets points to a 24-month worry-free warranty — confirm on the seller page you buy from.
• Compatibility lists include recent MacBook Pro / Air models among many phones and tablets. Anker is explicit: no MagSafe on this brick — use USB-C to USB-C.

That is the same desk map as my USB-C hubs and docking stations roundup: the 555 answers “ports,” this brick answers “watts at the wall.”

What I actually want from a Mac travel / desk brick

• One USB-C port that can feed a laptop hard. 100W single-port headroom covers MacBook Air and most 14-inch MacBook Pro days when you are on one cable.
• A second port for the phone without digging out another wall wart — accepting that the laptop share drops when both USB-C ports are busy (see Anker’s 65W + 35W split).
• One USB-A leftover for older earbuds cases, watch pucks, or hotel junk that never moved to USB-C.
• Small enough for a backpack next to the hub, not a second Apple 96W / 140W slab.
• Honest pairing with a hub. If you charge through the Anker 555, Anker’s hub story is roughly 100W in / ~85W to the laptop. The wall brick still needs to be a real PD charger — this is that class of brick.

The honest caveats

Multi-port power is shared, not three times 100W. Plug a laptop and a phone into both USB-C ports and Anker’s own table says you are in 65W + 35W territory, not 100W + 100W. All three ports busy drops the laptop-side USB-C further (Anker lists about 46W + 30W + 22.5W). If the Mac is the priority, use one USB-C alone, or park the phone on USB-A.

100W needs the right cable. USB Power Delivery at 100W wants a cable that can do 5A typically an E-Marker USB-C to USB-C cable rated for 100W. A thin phone cable can silently limit you. The A2343 listing’s standard “what you get” is the brick + guide, so budget a known-good 100W cable if you do not already own one.

A 16-inch MacBook Pro may want more than 100W peak. Apple ships hotter wall adapters on some 16-inch configs. A 100W GaN brick will still charge the machine; it may not match the absolute peak of Apple’s biggest adapter under heavy load. Fine for travel and many desk days. Not a claim that it replaces every 140W MagSafe story.

Not MagSafe. Anker says so on the product page. USB-C to USB-C only. If you want the magnetic latch, you are shopping MagSafe cables / Apple’s bricks, not this wall charger.

Upper USB-C for the laptop when both C ports are used. Anker recommends the upper port for notebooks when both USB-C ports are occupied. Boring detail. Worth remembering.

Price and stock move. When I checked, third-party deal writeups had this ASIN swinging from roughly mid-$40s on sale into a higher list band, and Amazon buy-box availability can look thin. I am not promising a price. Open the listing.

My honest buying call

I would buy the Anker Prime 100W (A2343 / B0C4DGBHY2) when I want one compact GaN brick for a MacBook Air or 14-inch Pro travel kit — laptop on one USB-C at up to 100W, phone on the other port or USB-A, foldable US plug, and a clear pairing with an Anker-style hub PD-in.

I would skip it if I need MagSafe, if I insist on simultaneous dual-laptop charging at high wattage (this is a 100W shared pie), if my 16-inch Pro must hit Apple’s absolute maximum charge rate under load, or if I specifically wanted the older 737 / A2148 120W story instead of this 100W Prime SKU.
