45W Laptop-Class Output, Built-In Retractable Cable & 300-Cycle Battery
The ACEFAST M34 is a 20000mAh power bank built for people who need to charge laptops and tablets on the move, not just phones. At 45W output through both the built-in USB-C cable and the dedicated USB-C port, it fast-charges a MacBook Air, Dell XPS 13, or iPad Pro at full rated speed — the threshold most competing 20000mAh banks fall short of at 22.5W.
The 65cm retractable flat USB-C cable is built directly into the unit and stows magnetically flush with the body when not in use. It removes the most common travel frustration — arriving somewhere without the right charging cable — by making the cable a permanent part of the device. The flat FFC construction resists kinking, and the magnetic slot keeps it secured during bag carry. A USB-A port adds 22.5W fast charging for a third device simultaneously, though total shared output drops to 15W when all three outputs are active at once.
The 300-cycle durability rating means the cell retains at least 80% of its 20000mAh capacity after 300 complete charge cycles — roughly 2–3 years of realistic travel use before any noticeable degradation. UN38.3 certification confirms it meets the international standard for lithium batteries in carry-on luggage. For highest charging speed, pair it with a compatible GaN wall charger that supports 30W input via the USB-C port.
Port Output Reference
| Built-in USB-C Cable | Output: up to 45W — 5V/3A · 9V/3A · 12V/3A · 15V/3A · 20V/2.25A (PPS / PD3.0 / PD2.0 / QC4+ / QC3.0 / QC2.0 / AFC / FCP / SCP) |
| USB-C Port | Output: up to 45W — same profile as built-in cable. Input: up to 30W (5V/3A · 9V/3A · 12V/2.5A · 15V/2A · 20V/1.5A) |
| USB-A Port | Output: up to 22.5W — 5V/3A · 9V/2A · 10V/2.25A · 12V/1.5A (QC3.0 / QC2.0 / AFC / FCP / SCP) |

When all three outputs are active simultaneously, total output is shared at 5V/3A (15W). Individual port speeds reduce when multiple devices are connected. Fast charge requires a compatible device and cable.

Frequently Asked Questions
Can it fast-charge a laptop at 45W?
Yes — both the built-in USB-C cable and the USB-C port output up to 45W, enough to fast-charge most USB-C ultrabooks including MacBook Air (M-series), Dell XPS 13, and Asus ZenBook. Laptops rated above 65W will charge at a reduced but still useful rate. Connect the laptop as the only device for maximum 45W; using multiple ports simultaneously reduces individual output to a shared 15W total.
How many times can it charge a phone?
The rated output is 11600mAh at 5V/3A after conversion losses. A typical 4500–5000mAh phone gets roughly 2–2.5 full charges; a 10000mAh tablet gets approximately one full charge with capacity left over for earbuds or a smartwatch alongside it.
Is the M34 allowed on flights?
Yes. It is UN38.3 certified — the international air-transport standard airlines and aviation authorities require for lithium batteries. At 20000mAh / 3.7V the energy content is approximately 74Wh, well within the 100Wh carry-on limit most airlines set. Always carry it in hand luggage, never checked baggage, as required by aviation regulations globally.
