Power Bank Fast Charging 12V/4.5A 10000mAh - Ultra Slim Portable

In this review the Power Bank Fast Charging 12V/4.5A by Ntaanoo is judged on speed, portability and everyday usefulness. The bottom line: this compact 10000mAh charger is for anyone who needs noticeably faster on-the-go top-ups and a very slim travel companion. Its claim of up to 22.5W DC pass-through charging stands out, delivering rapid boosts to modern phones while staying about the weight and size of a current flagship handset, which makes it especially appealing for commuters and travelers who dislike bulky battery packs.

Key Features

• Fast Charging: Supports up to 12V/4.5A (22.5W) DC pass-through to charge compatible phones significantly faster than standard 2A or 3A power banks.
• Portable Size: Measures 5.55 x 2.76 x 0.63 in and is thinner and smaller than many 10000mAh packs, making it easy to slip into a pocket or small bag.
• Dual Ports: USB-C supports both input and output while a USB-A port lets you charge two devices at once or share with a friend.
• Wide Compatibility: Works with recent iPhone series and most Android phones, able to charge an iPhone 12 multiple times and an iPhone 16 twice on a single charge.
• Safety System: The 2025 model adds short-circuit, overheating and overcharge protection plus additional safety features to protect phones and the battery bank.
• Included Items: Comes with a Type-C charging cable, user manual and a 2-year warranty for added confidence.

Who It's For

This power bank is best for travelers, daily commuters and users of modern smartphones who want faster top-ups without carrying a heavy brick. If you value thin styling that fits into pockets or handbag organizers and you regularly need a quick charge during a day out, this model is a practical choice.

Users who need extremely high-capacity multi-day backup or those who require a Lightning cable included should look elsewhere; this pack ships with a Type-C cable only. Also, people with older devices that cannot accept higher-voltage charging will not see the full 22.5W benefit.

Pros & Cons

Pros

• Very fast charging for compatible phones, reducing wait time for a meaningful battery boost.
• Ultra slim and lightweight design that rivals modern phones in portability.
• Dual-port convenience with USB-C input/output and an extra USB-A for sharing power.
• Comprehensive safety protections and a reassuring 2-year warranty.

Cons

• No Lightning cable included, so iPhone users must bring their own or use the included Type-C to Lightning cable if they have one.
• While reliable for everyday use, some customers reported mixed feedback on long-term reliability.
