Connector Size – This charger features a 3.5x1.35mm male plug , a common size for many Li-ion battery-powered devices. The pin comes with DC 3.5*1.35 male connector , doesn't fit with other sizes ( 4.0*1.7mm, 5.5*2.1mm). Find out how much power you need in watts (W), especially the output of your device. Check the charging protocol supported by your device. Not compatible with original smart curtain motors from brands such as Graber, Bali, or Somfy. Please verify your device model before purchasing. Communication Protocol (Critical!): The original charger contains a simple communication chip that establishes a “handshake protocol” with the management circuitry inside the motor or battery. Before charging begins, the device undergoes identification to confirm it is an original accessory. This anti-counterfeiting, safety, and quality control measure prevents charging from proceeding unless the protocol is recognized. Your universal charger lacks this protocol and will therefore be rejected. How to Choose the Right Battery Charger For You? Here’s what to consider Voltage Compatibility – Ensure the charger’s output voltage matches your device (7.2V, 7.4V, or 8.4V) . Using the wrong voltage can damage your battery. Safety Features – Look for overcharge & short-circuit protection (included in this adapter). LED Indicator – The built-in light turns red when charging and green when fully charged, ensuring safe power delivery. Long electrical cord Durable & Long Cable – The 118-inch (3m) white cord provides flexibility for charging at home, in the workshop, or on the go. Light-duty extension cords are useful household items for extending the reach of lamps or other electronics. The charger has a 118" lead and can charge a drained lithium-ion motor in app. 4 to 6 hours depending on the motor size, be able to plug it on different outlets. MUST VERIFY 1.
