Review: A Portable Powerhouse, Fully Charged - The Charmast Power Bank arrived in a no-frills, practical package. The delivery was prompt, and the box, though simple, was sturdy and did an excellent job of protecting the product. Unboxing revealed a sleek, slim device that felt both professional and durable. The look of this power bank is minimalist and sophisticated. The slim, black design is understated, with a smooth, matte finish that gives it a high-end feel. It’s a very clean and modern aesthetic that won't look out of place in a business meeting or a casual coffee shop. The multitude of ports—three inputs and four outputs—are neatly arranged and well-labeled, a testament to the product’s focus on versatility and user-friendliness. When you pick it up, the power bank has a solid and surprisingly lightweight feel for its large 26800mAh capacity. It's thin enough to slip into a bag or a large pocket, and the smooth surface feels comfortable in your hand. The ports are securely fitted, and the cables plug in with a reassuring click. It feels like a device that's built to withstand the rigors of travel and daily use, and its build quality inspires confidence. I’ve used this power bank for a wide range of tasks, and it has become an indispensable travel companion. Its colossal capacity has been a lifesaver on long flights and multi-day trips where power outlets are scarce. It’s perfect for charging my smartphone and tablet simultaneously, and I've even used it to keep a small portable speaker or headphones running during an outdoor event. Most recently, I've discovered its perfect use for powering my Lego lighting kits, giving me a reliable and long-lasting power source without having to rely on multiple batteries. The ability to charge up to four devices at once is a fantastic feature, making it the central hub for all my electronics. This power bank is a powerful and reliable solution for anyone who needs to keep their devices charged and ready to go, no matter where their day takes them.

## Questions & Answers

**Q: What happens after the 'with over 500 battery charge life cycle'?**
A: The storage capacity of the battery is reduced, so maybe it will be 80% as good as it was before. It shouldn't just stop working :)

**Q: Can I bring it on a plane? Is the product certified for it?**
A: You can take this power bank on a plane. The cells within this power bank are lithium ion with a nominal voltage of 3.7V (5V is the output voltage at the USB port, not the voltage of the cells within the battery). Therefore the Wh rating for this power bank is 99.16Wh, below the limit.

**Q: I have just received and am using the battery pack. I am wondering why output 3 is coloured orange, whilst output 2 is blue. Are they different?**
A: Blue has higher power output

**Q: Can you use all three input ports to recharge more quickly or must you only use one?**
A: Hello my friend, even though this portable charger providing 3 different input ports to recharge itself, you can only choose one of them at one time. Thanks. Charmast.
