- During pass-through charging with two devices, one USB-C port limits output to 100W.
- Does not support wireless charging.
Dimension Scores
Offers 140W Power Delivery 3.1 output for devices and recharges itself at up to 125W, which is among the fastest available for power banks.
Constructed with high-quality plastic, though some users desire a metal casing, and there are isolated reports of early unit failure.
Features two USB-C and one USB-A port, supporting a broad range of modern devices from iPhones to MacBooks and Vision Pro.
Measures 6.1 × 2.1 × 1.9 inches and weighs 22 oz, making it larger and heavier than many power banks, though still airline-safe.
Best For
- Users needing to rapidly charge modern laptops (e.g., MacBook Pro) and smartphones on the go.
- Travelers who require a high-capacity, airline-safe power bank for multiple devices.
- Individuals who value real-time charging data and battery status via a digital display.
- Powering devices like the Steam Deck or Nintendo Switch at high wattages.
Not Recommended For
- Users primarily charging older phones or devices that cannot utilize high wattage charging.
- Those seeking a very compact or lightweight power bank, as it measures 6.1 × 2.1 × 1.9 inches and weighs 22 oz.
- Anyone expecting wireless charging capabilities.
Watch Out For
- The actual usable energy is around 72Wh, not the full 86.4Wh (24,000mAh), due to conversion losses.
- Charging older devices like an iPhone 6s Plus or iPad Pro 3rd gen might only yield 9W or 15W, respectively, despite the power bank's 140W capability.
- One user reported their first unit stopped functioning after 3-4 cycles, requiring a replacement.
- The power bank does not function as an uninterruptible power supply (UPS); connected devices will reset if the input power is interrupted.
- Overload recovery can be inconsistent, sometimes requiring manual unplugging and re-plugging of cables.

What Buyers Say
Users frequently highlight the power bank's ability to charge high-wattage devices like laptops and Steam Decks at their maximum speeds, which is a significant advantage over lower-powered alternatives. The smart digital display is consistently praised for its real-time wattage and battery percentage readouts, making it easy to monitor charging status. However, some users express disappointment with the actual usable capacity, which falls short of the advertised 24,000mAh due to efficiency losses. There are also observations that older devices don't benefit from the high wattage, charging at their own limited speeds.
“I bought this for my MacBook Pro and it charges it so fast, like, half full in 40 minutes, but my old iPhone still charges slow, which is kinda annoying but not the power bank's fault. The screen is super cool though, I can see exactly how much power is going in and out.”
Common Praise
- Charges devices like laptops and gaming handhelds at their highest possible wattage.
- The smart display clearly shows real-time wattage input/output and battery percentage.
- High 24,000mAh capacity provides multiple charges for modern smartphones and tablets.
- Recharges itself very quickly, especially when using a 140W charger.
- Includes a 140W USB-C to USB-C cable and a travel pouch.
- The plastic casing feels high quality despite not being metal.
Common Complaints
- Real-world usable capacity is closer to 72Wh, not the full 86.4Wh, due to efficiency losses.
- Older phones and tablets do not charge at the power bank's maximum 140W, limited by the device's own charging capabilities.
- The unit is physically larger and heavier than expected by some users.
- Some of the smaller numbers on the digital display are difficult to read without close inspection.
- Pass-through charging limits one USB-C port to 100W when two devices are connected.
- Recovery from an overload condition can be inconsistent, sometimes requiring a cable re-plug.
Ownership Tips
- The power bank's efficiency means you won't get the full 24,000mAh of usable power, so factor in about 83% of that for actual device charging.
- To achieve the fastest self-recharge times, you'll need a 140W wall charger, which isn't included.
- The digital display is genuinely useful for understanding power flow, especially when troubleshooting slow charging on a device.
- While it's airline-safe, its 22 oz weight and 6.1 × 2.1 × 1.9 inch dimensions mean it's a noticeable item in a carry-on.
- The included USB-C to USB-C cable is rated for 140W, which is essential for utilizing the power bank's full output.

Will this power bank fast charge my older iPhone?

Buying Guide
When you're looking at power banks, especially for laptops, 'mAh' (milliampere-hours) tells you the raw capacity, but 'Wh' (watt-hours) is a better indicator of how much actual energy it can deliver, especially for higher voltage devices. Also, pay attention to the 'W' (wattage) output, as this determines how fast it can charge your devices. A higher wattage means faster charging for compatible devices, but your device also needs to support that speed. Don't forget to check the number and type of ports you need.

Alternatives
If this power bank is too large or powerful for your needs, look for models with lower mAh capacities and wattage outputs (e.g., 10,000mAh or 20,000mAh with 65W or 100W output) if you primarily charge phones or smaller devices. If you need even more power, search for power banks with capacities above 24,000mAh and higher wattage outputs, keeping in mind airline restrictions.
