Can the Anker 733 65W Charge Your Laptop? Full Test
The Anker 733’s 65W output places it in a unique tier — powerful enough to charge most thin-and-light laptops, while remaining compact enough for everyday carry. But how well does it actually perform with a MacBook Air or Windows ultrabook?

MacBook Air Compatibility
MacBook Air 13-inch (M1, M2, M3)
The MacBook Air 13-inch has a 30W native charger and supports USB-C PD charging up to 30W (M1/M2) or 35W (M3 dual-port).
Anker 733 result in wall mode: Delivers ~30–35W to the MacBook — effectively matching the original charger speed. From 20–80% takes approximately 45–55 minutes.
In battery mode: Delivers ~22–25W — noticeably slower, but will extend your MacBook’s working time by 2–3 hours per bank charge.
MacBook Air 15-inch (M2, M3)
The 15-inch Air’s larger battery benefits from higher wattage. Apple recommends 35W minimum for reasonable speed, and up to 70W for fast charging.
Anker 733 result in wall mode: Delivers ~45W — slower than the 70W Apple brick but charges from 20–80% in approximately 60–70 minutes.
In battery mode: Delivers ~22–30W — adds about 1.5–2 hours of use per battery bank charge.
MacBook Pro 14-inch / 16-inch
MacBook Pro models benefit most from higher wattage (96W–140W). The Anker 733’s 65W ceiling means:
- 14-inch MBP: Charges at reduced speed (about 50% of native charger rate)
- 16-inch MBP: Will charge very slowly — mainly useful to prevent battery drain during use, not for rapid charging
Windows Ultrabooks
| Laptop | Rated Charging Wattage | Anker 733 Delivered | Speed vs Native |
|---|---|---|---|
| Dell XPS 13 | 45W | ~42W | ~93% |
| Lenovo ThinkPad X1 | 65W | ~62W | ~95% |
| HP Spectre x360 13 | 65W | ~61W | ~94% |
| ASUS ZenBook 14 | 65W | ~60W | ~92% |
| Surface Laptop 5 | 65W | ~58W | ~89% |
For 65W-rated laptops, the Anker 733 delivers near-native charging speed — a genuinely impressive result for a hybrid power bank.
Simultaneous Laptop + Phone Charging
When charging a MacBook Air and iPhone simultaneously in wall mode:
– MacBook Air 15: ~35W (USB-C 1)
– iPhone 15 Pro: ~20W (USB-C 2)
– Total: ~55W (within 65W ceiling)
Both devices charge at near-optimal speed simultaneously — the key advantage of GaNPrime efficiency.
One Caveat: Battery Mode Laptop Charging
When the Anker 733 is unplugged (pure battery mode), laptop charging is slower:
– Max output drops to ~45W on USB-C 1
– For heavy CPU workloads, a 15-inch MacBook Air may consume power faster than the bank charges it
Best practice in battery mode: close unnecessary apps and reduce screen brightness to stay in a net-positive charging state.
