1. Smart and Innovative 21700 battery system - power solution.
Includes:
One NITECORE 21700 "i" series battery
A magnetic lamp ML21
A magnetic cover with a USB port that doubles as a Power Bank
A magnetic cover with a USB port that works as a Charger.
AWARDED as an IDEA 2020 Finalist
2020 marks the 40th anniversary of the International Excellence Award (IDEA), one of the longest-running and most prestigious award programs
design that exist together with the RED DOT AWARD, the iF Designe Award and the Good Design (G-Mark). It was originally established to recognize the
outstanding achievements in industrial design, the program has since evolved to emphasize design in many related
disciplines including design strategy, branding, digital interaction and more
2. An Innovative energy solution
The "i" series 21700 smart battery system consists of the ML21 magnetic lamp, the MC21 magnetic charger and the MBP21 magnetic power bank.
Designed to provide a stable source of energy with the least possible weight for outdoor activities, it can provide the necessary
lighting but also the transfer of energy between various devices during the activities.
3. The 21700 "i" battery series is a revolutionary and very powerful upgrade.
(Patent No.ZL201820118916.0, U.S. Patent Pending)
* "i" series batteries are a patented product designed by NITECORE.
* Enables very efficient performance by reducing power loss due to internal resistance
* It has two output sides with positive and negative poles on both ends as well as very high energy density.
* Compatible with modular extensions of smart communications and control systems.
4. Excellent energy density!
An "i" series 21700 battery has an energy density of up to 240mWh/g
11% more than 18650 batteries
5. Unprecedented battery performance
The dual polarities of the "i" series 21700 batteries on both sides broke the establishment that wants the lens head to be connected to the
its tail so as to reduce its weight and size. Thus the internal resistance is extremely reduced so that it offers its energy alone
to power the lens. Thanks to this innovative technology and technique, more possibilities can be applied to the design
of NITECORE lenses.
6. ML21 High CRi magnetic lighting module
Lighting with a maximum power of up to 80 Lumens, it is ideal either to be held in the hand or to stand on its tail as a flashlight and cover
short distances for reading, camping or an emergency.
Diameter: 26mm
Height: 59.5mm
Weight: 12.8g
7. The ML21 is equipped with LEDs that have a high ability to reveal natural colors (CRi>90), emitting a warm smooth beam that
simulates natural sunlight and offers clear vision while reducing eye fatigue.
8. MC21 Magnetic charging unit
Extremely small in size, it significantly helps to reduce the weight of the equipment.
Diameter: 26mm
Height: 16mm
Weight: 7.2g
During charging, the red indicator light will be permanently on
When the battery is fully charged, the indicator light will turn blue to indicate the process is complete.
If there is a short circuit the indicator light will go out.
9. MBP21 Magnetic Power Bank
Combined with an "i" series 21700 battery it is intended to provide a stable power supply in the outdoor environment
Diameter: 26mm
Height: 29.50mm
Weight: 10.8g
10. Smart accessory 2 in 1
Use as a Power Bank: After placing the MBP21 into an "i" series 21700 battery, use a USB cable to connect a
external USB device to the output port to start the charging process.
Use as a Charger: After placing the MBP21 on an "I" series 2100 battery with the positive terminal marked (+), use a
USB cable to connect an external power source (eg a charger) to the input port to start the process.
11. Compatible with common chargers and many other devices
The "i" series 21700 batteries are compatible with common chargers such as NITECORE UMS2, UMS4, Ui2, Ui1 and others. They can also
power common flashlights that accept 21700 batteries and other compatible devices.
12. It has multiple types of insurance
- Overcharge protection
- Reverse polarity protection
- Over discharge protection
- Over voltage protection
