Battery Capacity and Output Ports
Battery Capacity
The KP4 features a built-in 10000mAh lithium battery with a total energy rating of 36Wh. This capacity supports extended runtime for connected devices during outages. The KP3 data does not list a specific mAh or Wh rating. You should check the manufacturer specifications for the KP3 capacity details. The KP4 provides a clear advantage here because you get a defined energy reserve to rely on. This is important if you need to keep multiple devices running for a longer period without power.
Output Ports
Connectivity differs significantly between the two units. The KP4 includes three DC outputs, one USB-A port, and one USB-C port. This allows you to power routers, modems, and other smart home devices simultaneously. The KP3 offers multi-port DC outputs but the data does not specify the exact number or type of ports. If you need to charge phones or use USB-powered gadgets, the KP4 is more versatile. The KP3 focuses on standard DC connections for networking gear.
Physical Dimensions
Size matters for tight spaces. The KP3 measures 4.53 inches in length, 3.27 inches in width, and 1.06 inches in height. The KP4 is wider at 4.72 inches by 4.72 inches, but thinner at 1.1 inches in length. The KP3 has a slightly more compact footprint for small routers. The KP4 is square and designed to be wall-mountable. If you have limited shelf space, the KP3 might fit better. If you prefer wall mounting, the KP4 design supports that installation method.
Weight
Portability and installation weight are minor factors for stationary UPS units. The KP3 weighs 10.6 ounces. The KP4 weighs 12.5 ounces. The difference is 1.9 ounces. This slight weight increase in the KP4 is due to its larger battery capacity. For most users, this difference is negligible. Both units are light enough to be handled easily. The KP3 is marginally lighter, but the KP4 provides more power. Neither unit has a significant weight advantage for practical use.
Voltage Options
The KP4 supports multiple voltage outputs including 5V, 9V, and 12V via USB-C and DC ports. This flexibility helps you connect various devices with different power requirements. The KP3 data does not list specific voltage options or multi-voltage support. It is described as ideal for routers and modems, which typically use 12V. If you have devices requiring 5V or 9V, the KP4 is the better choice. The KP4 adapts to more device types without needing extra adapters.
Which Marsriva UPS fits your setup
You need the smallest possible footprint
The KP3 measures 3.27 by 1.06 by 4.53 inches. It weighs 10.6 ounces. This compact size fits tight spaces better than the KP4. If your router or modem has limited clearance, this smaller unit ensures a clean install without taking up extra room on your desk or shelf.
You want to power multiple devices
The KP4 includes three DC outputs plus USB-A and USB-C ports. This allows you to connect a router, modem, and CCTV camera simultaneously. The KP3 data does not list multiple output ports. If you need to keep several smart home devices online during an outage, the KP4 connectivity is essential.
You need long battery backup time
The KP4 features a 10000mAh lithium battery with 36Wh of energy. This capacity supports extended runtime for connected devices during outages. The KP3 data does not list a specific mAh or Wh rating. For longer internet uptime when power is down, the higher capacity of the KP4 provides more reliability.
You prefer wall mounting flexibility
The KP4 is designed with wall-mount support and a form factor suited for vertical installation. The KP3 is described as having a compact design but does not explicitly list wall-mount features. If you want to save desk space by mounting the UPS on a wall near your networking gear, the KP4 is the better choice.
