👍 Pros & 👎 Cons
👍 Pros
- Solid laptop support with up to 65 W to a single device
- The built-in USB-C cable reduces clutter
- Charges multiple devices simultaneously
- The digital battery indicator shows the exact charge level
- Travel-friendly size and airline-safe capacity
👎 Cons
- Not the highest laptop output compared with premium high-wattage models (e.g., 100 W+)

🎯 Who Should Buy This?
This power bank is a strong fit if you:
- Want a power bank that can keep your laptop charged away from outlets?
- Prefer built-in cable convenience and fewer wires to carry.
- Need a versatile unit for phones, tablets, and USB-C laptops.
- If you often travel or carry out your work in places where electricity isn’t consistently available.
It might be less ideal if you’re looking for peak laptop charging power (100 W+) or prioritise the absolute highest capacity — in which case larger, heavier units from other models could be worth exploring.
