Its adjustable charging bay supports both compact cells and larger battery formats, including 20700-, 21700- and 26650-size batteries.\n\u003c\/p\u003e\n\n\u003cp\u003e\nPower is supplied through a USB-C input, allowing the charger to be used with a compatible USB adapter, power bank or 5 V solar power source. The maximum charging current is 1000 mA, making the UI1 a practical charger for batteries used in flashlights, optics and other compatible electronic equipment.\n\u003c\/p\u003e\n\n\u003ch3\u003eAutomatic CC\/CV charging\u003c\/h3\u003e\n\n\u003cp\u003e\nThe UI1 automatically selects constant-current and constant-voltage charging to suit the installed battery. When the battery is fully charged, the charger terminates the charging process automatically.\n\u003c\/p\u003e\n\n\u003cp\u003e\nIf the installed battery voltage is above 2.9 V, the charger uses its standard charging mode with a maximum current of 1000 mA. Batteries below 2.9 V are charged automatically in a low-current mode at 100 mA to reduce stress on the cell.\n\u003c\/p\u003e\n\n\u003ch3\u003eOver-discharged battery activation\u003c\/h3\u003e\n\n\u003cp\u003e\nThe charger can test and attempt to activate an over-discharged Li-ion battery equipped with a protection circuit before beginning normal charging. Batteries that are damaged, leaking, deformed or cannot be safely activated must not be used.\n\u003c\/p\u003e\n\n\u003ch3\u003eClear charging indicators\u003c\/h3\u003e\n\n\u003cp\u003e\nThree indicator lights provide a simple real-time display of the battery level and charging progress. When charging is complete, all three indicators remain steadily illuminated and the charger automatically stops charging.\n\u003c\/p\u003e\n\n\u003ch3\u003eMultiple safety protections\u003c\/h3\u003e\n\n\u003cp\u003e\nThe UI1 includes reverse-polarity protection and short-circuit protection. If a battery is installed incorrectly or a short circuit is detected, all three indicators flash to signal an error.\n\u003c\/p\u003e\n\n\u003cp\u003e\nIntelligent thermal protection monitors the charger during operation. If excessive heat is detected, the charger automatically regulates the charging current to help protect both the charger and the battery.\n\u003c\/p\u003e\n\n\u003ch3\u003eCompact and durable construction\u003c\/h3\u003e\n\n\u003cp\u003e\nThe charger is manufactured from durable, flame-retardant polycarbonate. Its compact dimensions and approximately 40.5 g weight make it easy to carry in an equipment bag, travel kit or outdoor charging setup.\n\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-slot charger for cylindrical Li-ion and IMR batteries\u003c\/li\u003e\n  \u003cli\u003eCompatible with rechargeable 3.6 V and 3.7 V cells\u003c\/li\u003e\n  \u003cli\u003eUSB-C power input\u003c\/li\u003e\n  \u003cli\u003eMaximum charging current of 1000 mA\u003c\/li\u003e\n  \u003cli\u003eAutomatic CC\/CV charging-mode selection\u003c\/li\u003e\n  \u003cli\u003eAutomatic charging termination when the battery is full\u003c\/li\u003e\n  \u003cli\u003eAutomatic 100 mA low-current charging below 2.9 V\u003c\/li\u003e\n  \u003cli\u003eActivation function for over-discharged protected Li-ion batteries\u003c\/li\u003e\n  \u003cli\u003eThree charging and battery-level indicators\u003c\/li\u003e\n  \u003cli\u003eReverse-polarity protection\u003c\/li\u003e\n  \u003cli\u003eShort-circuit protection\u003c\/li\u003e\n  \u003cli\u003eIntelligent thermal protection\u003c\/li\u003e\n  \u003cli\u003eCompatible with USB adapters, power banks and suitable 5 V solar power sources\u003c\/li\u003e\n  \u003cli\u003eDurable, flame-retardant polycarbonate construction\u003c\/li\u003e\n  \u003cli\u003eCE and FCC certified\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eManufacturer: Nitecore\u003c\/li\u003e\n  \u003cli\u003eModel: UI1\u003c\/li\u003e\n  \u003cli\u003eProduct type: Li-ion and IMR battery charger\u003c\/li\u003e\n  \u003cli\u003eNumber of charging slots: 1\u003c\/li\u003e\n  \u003cli\u003eInput: DC 5 V \/ 1 A, 5 W\u003c\/li\u003e\n  \u003cli\u003eOutput: 4.2 V ±1%\u003c\/li\u003e\n  \u003cli\u003eMaximum charging current: 1000 mA\u003c\/li\u003e\n  \u003cli\u003eLow-current charging: 100 mA when battery voltage is below 2.9 V\u003c\/li\u003e\n  \u003cli\u003eSupported battery voltage: rechargeable 3.6 V and 3.7 V Li-ion \/ IMR\u003c\/li\u003e\n  \u003cli\u003eCharging indicators: 3\u003c\/li\u003e\n  \u003cli\u003eMaterial: flame-retardant polycarbonate\u003c\/li\u003e\n  \u003cli\u003eDimensions: approximately 122.5 × 29.2 × 32 mm\u003c\/li\u003e\n  \u003cli\u003eWeight: approximately 40.5 g\u003c\/li\u003e\n  \u003cli\u003eCertifications: CE and FCC\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible battery sizes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e10340, 10350, 10440 and 10500\u003c\/li\u003e\n  \u003cli\u003e12340, 12500 and 12650\u003c\/li\u003e\n  \u003cli\u003e13450, 13500 and 13650\u003c\/li\u003e\n  \u003cli\u003e14430, 14500 and 14650\u003c\/li\u003e\n  \u003cli\u003e16340 \/ RCR123, 16500 and 16650\u003c\/li\u003e\n  \u003cli\u003e17350, 17500, 17650 and 17670\u003c\/li\u003e\n  \u003cli\u003e18350, 18490, 18500 and 18650\u003c\/li\u003e\n  \u003cli\u003e20700 and 21700\u003c\/li\u003e\n  \u003cli\u003e22500 and 22650\u003c\/li\u003e\n  \u003cli\u003e25500, 26500 and 26650\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e The UI1 is intended for compatible cylindrical rechargeable 3.6 V and 3.7 V Li-ion or IMR batteries.
