In today’s pursuit of high-performance devices and lightweight travel, power solutions often present us with a dilemma: high-capacity power banks are bulky, and their airline compliance is uncertain, while dedicated batteries, though good, can’t “revive” your phone in an emergency. Is there a product that offers the best of both worlds?
Building upon Keeppower’s years of industry experience and R&D commitment to innovation and superior products/services and following the successful launch last year of our higher-capacity protected 21700 6000Batterie au lithium mAh(P2160C), we are proud to introduce the newly designed P2160TC Type-C Rechargeable Li-ion Battery. It is more than just a battery; it’s a versatile all-rounder that integrates high performance, convenient charging, and multiple application scenarios. With its elegant yet robust design, it redefines the boundaries of portable power experience.
Core Advantages: What Makes It an “All-in-One” Solution?
High-Energy Core, Long-Lasting Reliability
The P2160TC uses a high-quality 21700 cell. It delivers an impressive 6000mAh capacity. Under a 3A discharge, it reaches 6076mAh. This ensures long-lasting, stable power. It’s perfect for professional flashlights, laser rangefinders, and outdoor GPS units. The battery reduces power anxiety in outdoor activities or emergencies.

Simplified Charging, One USB-C Cable Does It All
Say goodbye to dedicated chargers and tangled cables. The product features an integrated Type-C charging port. You can use the same Type-C cable that charges your phone or laptop to replenish its energy. This not only streamlines your travel kit but also saves you the cost of purchasing an additional charger, enabling true “charge anywhere, anytime” convenience.
Compact and Lightweight, Effortless to Carry
Through precisely engineered design, the P2160TC measures just 21.8mm(D)× 77mm(L) and weighs under 80g. It fits easily into a compact women’s handbag or a side pocket of a backpack. Its 21700 form factor ensures compatibility with many flashlights and electronic devices. This provides excellent versatility for various applications.
Hidden Skill: Emergency Power Bank Mode
This is where the P2160TC subverts conventional thinking. Its built-in intelligent circuit design enables a discharge function. With the included adapter (or compatible cable), this “lipstick-sized” battery can instantly transform into an emergency power bank. While not intended as a primary daily charger, it provides crucial backup power to recharge your phone, Écouteurs Bluetooth, or other USB devices, saving you from the frustration of a dead phone at critical moments.
Airline Compliant, Worry-Free Travel (Key Differentiating Advantage)
In recent years, due to safety incidents involving some polymer power banks, airline security regulations worldwide have become increasingly strict and subject to frequent changes. This has led to numerous cases of passengers having their expensive power banks confiscated or discarded. The P2160TC fundamentally solves this pain point.
As a standard, identifiable, single lithium-ion battery with clear specifications (21700/6000mAh), it falls under clearly defined and well-regulated category for global air transport. To comply with aviation rules, insulate the terminals to prevent short circuits. Keep the battery in its original case or a dedicated battery case. This ensures safe, legal, and worry-free travel onboard. This makes it the most reliable “in-flight power companion” for international travelers and frequent flyers.
Comprehensive Certifications
The product has passed multiple international safety certifications including ONU38.3, CE, and ROHS, ensuring complete compliance and peace of mind.

Important Notes for Optimal Use
To ensure the best experience, please note the following key points: Efficiency Conversion Reality: Due to inherent energy conversion losses in the circuit, the effective power output when used as a power bank will be less than the cell’s native 6000mAh capacity. This is a physical characteristic of all portable power sources.
Visualizing Performance: The Discharge Curve
Beyond understanding efficiency, you can visually appreciate the P2160TC’s quality through its discharge curve below. The flat voltage plateau demonstrates the excellence of the cell and the stability of the circuit control, ensuring predictable runtime and performance in your devices.
