65W Mini DC UPS

As a high-performance mini UPS, the 65W Mini DC UPS (model DC6519) uses high-quality battery cells and intelligent control circuitry to provide stable backup power for laptops, mini PCs, all-in-one computers, cameras, routers, ONTs, CPAPs, and other devices.

It automatically charges and directly supplies power to devices when mains power is normal, and switches to battery power within milliseconds when mains power is interrupted, ensuring that devices do not restart and data is not lost.

Product Parameter

Key Features

1. 65W Continuous Output

The DC6519 series boasts a total output power of 65W, stably driving various portable or desktop devices and meeting the daily mobile office and home emergency power needs.

2. Intelligent CPU Control

Built-in advanced MCU or dedicated IC precisely controls the voltage output of each port, ensuring stable and clean DC power supply.

3. Resettable Thermal Protection

In addition to overcurrent and overheat protection provided by the IC, each output DC port is equipped with a resettable thermal fuse for further enhanced safety.

4. Uninterruptible Power Supply (UPS) Function

Automatically charges the internal battery and supplies power to the load when the mains power is normal; automatically switches to battery power mode after a mains power failure, eliminating the need to restart the load.

5. New 26700 Lithium Iron Phosphate Battery

The 65W Mini DC UPS uses six new 3.2V 5000mAh 26700 cylindrical lithium iron phosphate cells to form a 96Wh battery pack, ensuring long battery life. Never use recycled battery cells.

6. Battery Level Indicator

The LCD display shows battery voltage, remaining battery percentage, and charging status clearly and intuitively.

FAQ

1. Can the 65W Mini DC UPS power multiple devices simultaneously?

Yes. All output ports with a total power not exceeding 65W (peak 100W) can be used simultaneously. For example, you can charge a laptop (45W) and a mobile phone (15W) at the same time.

2. How long does it take to fully charge?

Using a 15V/4A power adapter, it takes approximately 2 hours to fully charge; using a 12V car charger or an 18V solar panel, the time depends on the input power, typically 3-5 hours.

3. Does it support simultaneous charging and discharging (UPS mode)?

Yes. This is its core function: when AC power is connected, the device is directly powered by the external power source and simultaneously charges the internal battery; when AC power is disconnected, it automatically switches to battery power without restarting the load.

4. Can I use a higher wattage solar panel?

It is recommended to use an 18V solar panel with a power rating of 100W or less. Input voltage exceeding 20V may damage the device; please strictly adhere to the specifications.

5. What is the battery life?

It uses lithium iron phosphate cells with a cycle life of ≥2000 cycles (80% DOD), which can serve for many years under normal use.

6. What voltage outputs does the device support?

The DC5525 interface provides fixed 12V and 19V; the USB-C PD port supports 5V/9V/12V/15V/20V auto-negotiation; the DC5521 and USB-A provide 5V.
