Step 1: Determine the operating voltage and current of the load device (such as common routers, optical modems, switches, surveillance cameras, fingerprint scanners, etc.) using the UPS. This is typically indicated on the back of the device by a silkscreen or sticker, typically 5V, 9V, or 12V. L1L: After confirming the voltage and current information, connect the load device to the corresponding DC port on the UPS. For example, if the load device is 5V, connect it to the 5V-DC port on the UPS. Connecting it incorrectly may damage the device.Step 3: When replacing new batteries, be sure to follow the instructions in the manual. The battery model must be 18650 and the capacity must be at least 2000mAh. Do not connect the battery with the wrong polarity. Otherwise, the device not power on.Product Name: 36W Uninterruptible Power Supply (UPS)Product Model: DC1036LInput Current: 85-265VAC 50-60HzOutput Current: 16.4V/DC 2.5AOutput Power: 36WBattery Type: Lithium-ion BatteryBattery Model: 18650Battery Capacity: 2000mAh x 4Dimensions: 171 x 113 x 37mmNet Weight: Approximately 446gDisplay: LED(4 x 18650 rechargeable batteries are not included in the shipment)Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.Voltage: AC220VColor: BlackMaterial: ABSPackage Contents:1 set * DC UPS uninterruptible powerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
