BT-20/21700 Power Bank: Portable and Powerful, Essential for Travel

The BT-20 power bank features a card-like design that is extremely portable. With detachable batteries and the ability to recycle dismantled/recycled batteries to save costs, it is suitable for flat-top 21700 batteries and can also be compatible with 18650 batteries. It is ideal for both home use and outdoor activities such as hiking and camping.

Product features:
1.Wide compatibility: It is not compatible with non-standard 21700 batteries with a diameter of more than 21.8 millimeters (such as Panasonic 21700A), but it is compatible with 99% of flat-head 21700 lithium batteries on the market. When combined with a direct tube, it can also be compatible with 18650 lithium batteries. The conversion efficiency is high, and in ECO mode, it can reach up to 85%.

  1. Lightweight for travel: A single battery has a capacity of 5000mAh. The product itself weighs only 37 grams, and the travel weight is within 107 grams. With a total capacity of no more than 27000mAh, it can be carried on airplanes.
  2. Multiple protocols: It is compatible with various protocols such as QC/PD/PPS/FCP/DCP/AFC/PE and is suitable for devices from Apple, OV series, Huawei, Honor, and Xiaomi.

Design structure:
1.Type-C port for input and output. Manual battery placement. Symmetrical design, operable with either hand. Anti-reverse connection and anti-recharge. One-click battery replacement. Automatic power detection upon power-on. After 5000 tests, there is no significant attenuation in springs, latches, and feel.
2.Porous vacuum silicon insulation. Contains 3μ gold-plated phosphor copper contacts and 2.5 milli-ohm parallel MOSFETs for multiple protections. Made of V0 fire-resistant PC engineering plastic. Equipped with a waterproof and flame-retardant Oxford cloth battery pack. There is a Velcro hook on the back, which can hold 21700/18650 batteries and support power supply for various devices.

Power display and function switching:
1.Power display: cyan (>40%), orange (20%-40%), red (5%-20%), and flashing red light (<5%).
2.Function switching: There are standard mode (fast charge output of 5V/9V/12V), ECO mode (green indicator light, 5V output, high efficiency and low temperature), and low-current mode (indicator light cycle animation, device does not sleep). ECO and low-current modes need to be switched back to standard mode first before switching.

Safety warnings and precautions:
1.The battery cover has insulation and anti-counterfeiting functions. Do not tear it. Batteries with damaged or missing covers are prohibited. Do not use or store in overheated or humid environments. Stop using if there is bulging.

  1. When inserting a battery, it takes 5 seconds for power detection. At this time, charging is not allowed (including reverse charging of some mobile phones). Otherwise, the detection will fail. You can restart by reinserting the battery.
