- The unit is described as 'chunky' and 'not very thin but thick' for a 10,000mAh capacity, making it less pocketable than some might expect.
- Pass-through charging is not fast, making it less ideal for quick simultaneous charging.

What Buyers Say
The standout feature for many is definitely that built-in retractable USB-C cable; people are stoked about not having to remember an extra cord. The smart display is also a big hit, giving you all the battery info you could want, like percentage and wattage. However, don't expect that 45W to stick around for long, especially if you're trying to charge more than one thing at once, as the power output drops significantly. It's also a bit on the thicker side, so while it's compact, it might not disappear into your pocket.
“Okay, so I bought this because I'm always losing my charging cables, and that retractable one is a game-changer, seriously! It charges my S25 Ultra super fast when it's just that one phone, but if I try to charge my iPad too, it slows way down. Still, for a quick top-up on the go, it's pretty sweet.”
Common Praise
- The integrated 2.3 ft retractable USB-C cable means no more tangled cords or forgotten cables.
- The smart display provides useful real-time information like battery percentage, charging wattage, and temperature.
- Capable of fast charging a single device with its 45W max output.
- The ability to charge the power bank and a device simultaneously with pass-through charging is convenient.
- Its compact size, measuring 3.21 × 1.99 × 1.42", makes it easy to carry in bags or purses.
Common Complaints
- The 45W output isn't sustained, dropping to 30W and then 20W during a single charge.
- Charging multiple devices severely limits the power to each port, with some dropping to 7.5W.
- Some users find it 'chunky' or 'thick' for a portable charger, despite its overall small footprint.
- Concerns exist about the long-term durability of the retractable cable mechanism.
- Pass-through charging is not fast, making it slow for simultaneous charging and recharging.
Ownership Tips
- The smart display is actually super helpful, not just a gimmick, letting you see exactly how much juice is left and how fast things are charging.
- The retractable cable, while convenient, feels a bit delicate, so you might find yourself being extra careful with it.
- Even though it's 'compact,' it's got some heft and thickness to it, so it's more of a bag item than a truly pocketable one for some.
- If you're charging a laptop in a pinch, it'll work, but don't expect a full charge or sustained high power.
- The 2-hour recharge time for the power bank itself is pretty quick, which is a plus for daily use.

Buying Guide
When looking at portable chargers, you need to think about how much power you actually need and how you'll use it. Don't just look at the mAh; consider the wattage output, especially if you have newer phones or tablets that can handle faster charging. The convenience features, like a built-in cable, can make a huge difference in daily use, but also check if it supports charging multiple devices efficiently if that's your thing.
battery_capacity (10,000mAh)
This number tells you how much energy the power bank can store. 10,000mAh is enough to fully charge most modern smartphones 1-2 times, or give a tablet a significant boost, like having a spare fuel tank for your devices.
watts (45W Max)
This is the maximum power output, indicating how fast it can charge your devices. A higher wattage means quicker charging, especially for devices that support fast charging protocols, like filling a car with a high-flow pump versus a slow trickle.
connector (USB Type C, USB Type A, Retractable USB-C Cable)
These are the types of ports and cables available to connect your devices. Having both USB-C (especially a built-in one) and USB-A ensures compatibility with a wide range of gadgets, from the newest iPhones to older accessories, like having multiple adapter types for different outlets.
Alternatives
If this doesn't fit, look for power banks with higher sustained multi-port output for simultaneous fast charging, or a significantly thinner profile if pocketability is your top priority.
