1. Introduktion
The XTAR MP1S Intelligent USB Battery Charger is designed for charging various 3.7V Li-ion batteries, including 14650, 17670, 18650, 18700, and with the use of spacers, also 10440, 14500, 15270, 16340, and 18350 types. It features an advanced TC.CC.CV (Trickle Current, Constant Current, Constant Voltage) charging algorithm that continuously monitors battery status for safe and automatic charging. The charger is equipped with a protection circuit and intelligent temperature monitoring to ensure optimal performance and safety.
2. Sikkerhedsforanstaltninger
Please read and understand all safety warnings before using the charger.
- Kun indendørs brug: Hold enheden væk fra vand og fugt.
- Batterikompatibilitet: Only charge 3.7V Li-ion batteries. Charging other battery types may cause damage or injury.
- Ingen demontering: Disassembly or modification of the charger is strictly prohibited.
- Undgå kortslutninger: Short circuits are strictly prohibited and can cause severe damage to the charger and battery.
- Driftstemperatur: Ensure the charger is used within the recommended operating temperature range of 0~40℃.
3. Produktfunktioner
- Intelligent Charging Algorithm: Utilizes TC.CC.CV charging system for efficient and safe charging.
- Automatisk overvågning: Monitors battery status continuously throughout the charging process.
- Low Current Standby: Automatically enters a low current status (below 4uA) when the input voltage is removed, minimizing battery discharge.
- Opladningsvedligeholdelse: Continuously monitors the battery after charging is complete and restarts charging if the battery's voltage drops to 4.0V or below, maintaining a full charge.
- Temperaturkontrol: The charging management chip monitors its own temperature. If the detected temperature is too high, the charge current will automatically lower to protect the charger.
- Beskyttelseskredsløb: Incorporates a robust protection circuit for enhanced safety.
4. Kom godt i gang (opsætning)
Follow these steps to set up your XTAR MP1S charger:
- Tilslut strøm: Connect the USB cable to the charger's USB input port and then to a 5V USB power source (e.g., computer USB port, USB wall adapter, or car charger).
- Indsæt batteri: Carefully insert the 3.7V Li-ion battery into the charging slot, ensuring the correct polarity (+ and - ends) aligns with the markings on the charger. The positive (+) end of the battery should align with the positive contact on the charger, and the negative (-) end with the negative spring contact.
- Opladningsindikation: The charger will automatically begin charging. Refer to the operating section for details on charging status.

5. Betjening
The XTAR MP1S charger operates automatically once a compatible battery is inserted and power is connected.
- Opladningsproces: The charger employs a multi-stage TC.CC.CV charging method. It starts with a trickle current, then moves to constant current, and finally constant voltage to safely and efficiently charge your battery.
- Batterikompatibilitet: This charger is designed for 3.7V Li-ion batteries. It supports 14650, 17670, 18650, 18700, and with the use of spacers, also 10440, 14500, 15270, 16340, 18350 battery sizes.
- Automatisk genopladning: To ensure your battery remains fully charged, the charger will automatically restart charging if the battery voltage drops below 4.0V after a full charge.

6. Vedligeholdelse
Korrekt vedligeholdelse sikrer din opladeres levetid og optimale ydeevne:
- Hold tør: Always keep the charger in a dry environment. Avoid exposure to water or high humidity.
- Rengør kontakter: Periodically clean the charging contacts on the charger and your batteries with a dry, soft cloth to ensure good electrical connection.
- Opbevaring: Når den ikke er i brug, skal du opbevare opladeren på et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Undgå påvirkning: Tab ikke opladeren og udsæt den ikke for hårde stød.
7. Fejlfinding
If you encounter issues with your XTAR MP1S charger, consider the following:
- Opladeren tænder ikke:
- Sørg for, at USB-kablet er korrekt tilsluttet til både opladeren og strømkilden.
- Verify that the USB power source (e.g., wall adapter, computer port) is functional and providing 5V output.
- Batteri oplades ikke:
- Check that the battery is a 3.7V Li-ion type and is compatible with the charger (refer to compatible battery list).
- Sørg for, at batteriet er isat med den korrekte polaritet.
- Inspect the battery and charger contacts for dirt or damage. Clean if necessary.
- Check for any signs of short circuit on the battery or within the charger slot.
- Charging is Slow or Stops Prematurely:
- The charger's internal temperature control may reduce charging current if it detects overheating. Allow the charger to cool down in a well-ventilated area.
- Ensure the USB power source can provide sufficient current (500mA recommended).
