BT-20 POWER BANK - FLEXIBLE BATTERY MODULE BREAKTHROUGH & SUSTAINABLE POWER BANK - REDEFINING MOBILE ENERGY Rethink – Reduce – Reuse – Recycle – Redesign FAST-CHARGING DESIGN - QUICK BATTERY SWAP Out of battery? Just press a button, and your power bank is fully charged again! The BT-20, with its smart symmetrical design, is easy to operate with both hands, delivering a seamless and convenient experience anywhere. Simply insert a new battery, and the smart display will automatically recognize and show the energy level, keeping you ready for any situation. ECO-FRIENDLY AND COST-EFFECTIVE WITH BT-20 The BT-20 power bank is compatible with most flat-top Li-ion 21700 and 20700 batteries (without protective caps). * With an adapter, you can also use smaller 18650 batteries. These batteries are widely available and commonly used in vapes, flashlights, power banks, power tools, toys, DIY projects, and even electric vehicles and e-bikes. Recycling and reusing Li-ion batteries is an excellent way to reduce carbon emissions and environmental impact. We encourage you to use existing batteries (new or recycled). *Note: Batteries used should support a 5A discharge and 2A charge. FLEXIBLE CAPACITY - OUTSTANDING PERFORMANCE With just a single 5000mAh battery, the BT-20 can fully charge an iPhone 15 – offering a convenient and lightweight experience compared to bulky power banks. With the BT-20, you only carry the energy you need, no excess! The BT-20 has a conversion efficiency of approximately 80%, depending on the battery used. For example, with an EVE 50E 5000mAh battery (18.3Wh), the effective output energy reaches 4000mAh (14.6Wh), ensuring every charge is powerful and optimized. ULTRA-LIGHT & COMPACT The BT-20 weighs only about 38g and 105g with a battery – light as a feather! Smaller than a credit card, it easily fits in your pocket for on-the-go convenience. A power bank has never been this compact! SAFE CHARGING & DISCHARGING - VERSATILE The BT-20 safely charges most flat-top 21700, 20700, and 18650 batteries with a charging current of up to 2.5A. For optimal performance, use a charger with at least a 5V2A output. For discharging, the BT-20 supports fast charging for iPhone with 9V2.2A 20W PD and 15W-20W fast charging for most other devices, supporting various standards like QC, PD, PPS, FCP, DCP, AFC, and PE. If a device is not compatible with these standards, the BT-20 can still charge at the standard 5V2A 10W, meeting all your charging needs! PREMIUM, DURABLE MATERIALS The BT-20 is built with a robust mechanical structure, boasting a lifespan of over 5,000 usage cycles, ensuring over 3 years of operation even with 5 uses per day. The BT-20’s outer shell is made from flame-retardant PC (Polycarbonate) V0, a durable and recyclable material known for its exceptional longevity. Additionally, the gold-plated connectors enhance durability compared to standard nickel plating, ensuring long-term reliability to accompany you in any situation.
