Your router is one of the few devices in your home that never gets switched off — running continuously day and night, consuming electricity whether you are streaming 4K video or sound asleep. Most people have no idea how many watts their router actually uses, which makes it impossible to calculate what it costs to run or evaluate whether switching to a more efficient model is worthwhile. This guide gives you the exact wattage figures for every common router type — from basic budget models to high-performance gaming routers and enterprise-grade hardware — along with the methodology to measure your specific router’s actual consumption if you want the most accurate figure.
RingPlanet’s 5G fixed wireless router consolidates modem and router functions in a single compact, energy-efficient device — consuming less total power than the separate modem and router that cable internet requires. For a complete guide to router power consumption including annual cost calculations and energy-saving strategies, see our Router Power Consumption complete guide.
Why Router Wattage Varies So Much
Router wattage ranges from under 3 watts for the most basic models to over 50 watts for high-performance gaming and enterprise routers. Understanding what drives this variation helps evaluate whether a router’s power consumption is appropriate for its capabilities:
Number of wireless radios: Each frequency band the router broadcasts — 2.4GHz, 5GHz, 6GHz — requires a separate radio that consumes power independently. A single-band router has one radio. A tri-band Wi-Fi 6E router has three radios running simultaneously.
Processor speed and capability: Faster processors for handling higher data throughput, more simultaneous connections, and advanced features like QoS and VPN consume more power than slower processors in budget models.
Number and speed of Ethernet ports: Gigabit Ethernet ports consume slightly more power than Fast Ethernet ports. More ports mean more potential consumption from active connections.
Cooling requirements: High-performance routers generate more heat and require active fan cooling — adding to total consumption. Passive-cooled compact routers have no fan overhead.
Additional features: USB ports for network-attached storage, built-in VPN servers, parental control processing, and other advanced features all add processor load and power consumption.
Router Wattage by Category — Complete Data
Basic Single-Band Routers: 2–7W (Typical 3–5W)
Single-band routers broadcasting only on the 2.4GHz frequency represent the lowest-power category of consumer networking equipment. These routers are common as ISP-bundled equipment for basic cable plans and as budget purchases for light internet use.
Typical examples and their measured wattage:
- TP-Link TL-WR940N: approximately 3.5W
- Netgear WNR2000: approximately 4W
- D-Link DIR-619L: approximately 3W
At 3–5 watts, these routers cost approximately $4–$7 per year to run at the national average electricity rate — the lowest operating cost of any home networking category.
Dual-Band Wi-Fi 5 (AC) Routers: 6–18W (Typical 8–12W)
The most widely deployed consumer router category — dual-band 802.11ac (Wi-Fi 5) routers covering both 2.4GHz and 5GHz. This category spans a wide performance range from budget to high-end, with power consumption reflecting the capability tier.
Typical examples and their measured wattage:
- TP-Link Archer A7 (AC1750): approximately 8W
- Netgear R6700 Nighthawk (AC1750): approximately 10W
- ASUS RT-AC68U (AC1900): approximately 12W
- Netgear Nighthawk R7000 (AC1900): approximately 12W
- ASUS RT-AC88U (AC3100): approximately 15W
Dual-Band Wi-Fi 6 (AX) Routers: 8–22W (Typical 12–16W)
Wi-Fi 6 routers deliver improved throughput and better multi-device performance relative to Wi-Fi 5, but with modest increases in power consumption. The Wi-Fi 6 standard includes better power management for client devices — potentially reducing the total household power draw from devices connecting to a Wi-Fi 6 router, even if the router itself draws slightly more than its Wi-Fi 5 equivalent.
Typical examples and their measured wattage:
- TP-Link Archer AX21 (AX1800): approximately 9W
- TP-Link Archer AX55 (AX3000): approximately 12W
- Netgear Nighthawk RAX50 (AX5400): approximately 15W
- ASUS RT-AX86U (AX5700): approximately 18W
- Netgear Nighthawk RAXE500 (AXE11000): approximately 22W
Tri-Band Wi-Fi 6E Routers: 15–35W (Typical 20–28W)
Wi-Fi 6E routers add a third radio on the new 6GHz band — significantly increasing power consumption relative to dual-band models. Unless household devices actively use the 6GHz band — which requires Wi-Fi 6E client devices — the third radio consumes power without delivering any practical benefit.
Typical examples and their measured wattage:
- TP-Link Archer AXE75 (AXE5400): approximately 18W
- Netgear Nighthawk RAXE500: approximately 25W
- ASUS RT-AXE7800: approximately 20W
- Eero Max 7: approximately 22W
Gaming Routers: 15–50W (Typical 25–35W)
Gaming routers prioritize maximum throughput and minimum latency — often at the cost of significantly higher power consumption. Active cooling fans, more powerful processors, additional Ethernet ports, and RGB lighting all contribute to consumption levels that can be 3–5x that of a modest dual-band router.
Typical examples and their measured wattage:
- ASUS ROG Rapture GT-AX11000: approximately 35W
- Netgear Nighthawk XR1000: approximately 28W
- TP-Link Archer GX90: approximately 25W
- ASUS ROG Rapture GT-BE98: approximately 45W
For most households, gaming router performance exceeds what any residential internet plan can actually utilize — making the additional power consumption difficult to justify purely on performance grounds.
Mesh Wi-Fi System Nodes: 6–25W Per Node (Typical 10–18W)
Mesh system nodes vary significantly in power consumption based on the number of radios and processing capability. The total system consumption multiplies by the number of nodes deployed.
Typical per-node consumption:
- Eero 6+: approximately 8W per node
- Eero Pro 6E: approximately 12W per node
- Google Nest Wi-Fi Pro: approximately 14W per node
- TP-Link Deco XE75: approximately 15W per node
- Netgear Orbi RBR860S: approximately 22W per node (router unit)
- Netgear Orbi RBS860S: approximately 18W per node (satellite unit)
A three-node Netgear Orbi system can consume 58–62W continuously — more than a desktop computer in active use.

How to Measure Your Specific Router’s Wattage
Spec sheet wattage figures represent maximum consumption — actual operational consumption is typically 40–60% lower. For accurate real-world figures:
Method 1: Smart Plug with Energy Monitoring
Connect a smart plug with energy monitoring capability — Kasa EP25, Emporia Smart Plug, or equivalent — between the wall outlet and the router’s power adapter. The companion app displays real-time wattage and accumulates daily kWh consumption for precise annual cost calculation. This is the most practical and accurate method for most households.
Method 2: Kill-A-Watt Meter
A Kill-A-Watt plug-in power meter (approximately $25) provides real-time wattage display and cumulative kWh tracking. Plug the router into the Kill-A-Watt and leave it for 24–48 hours to capture consumption across multiple activity levels — the average wattage shown is your true operational figure.
Method 3: Check the Power Supply Label
The power adapter connected to the router lists its output voltage and maximum current — for example, “12V 2A.” Multiplying these figures (12V × 2A = 24W) gives the maximum possible power draw. Actual consumption is typically 40–60% of this figure under normal operating conditions — so a 24W maximum adapter likely draws 10–14W in practice.
What the DOE’s Energy Star Data Shows for Routers
The U.S. Department of Energy’s Energy Star program certifies small network equipment — including routers and modems — that meet efficiency standards. Energy Star-certified routers must meet maximum power consumption thresholds based on their capability tier. For consumers seeking energy-efficient routers, the Energy Star product list provides verified efficiency data across certified models — a more reliable basis for comparison than manufacturer spec sheets alone.
Frequently Asked Questions
How many watts does a typical home router use?
A typical home router uses 8–15 watts continuously. Basic single-band routers use 3–5 watts. High-performance gaming and tri-band routers use 20–35 watts. The exact figure depends on the router’s age, capability tier, and which frequency bands are active.
Does a router use more power when more devices are connected?
Slightly — a router managing many simultaneous active connections consumes marginally more processor resources and radio power than a router managing a few idle connections. The increase is typically 1–5 watts and is most noticeable on high-performance routers with many active IoT devices.
What is the most energy-efficient router type?
Modern dual-band Wi-Fi 6 routers deliver the best performance-to-power ratio — capable of handling all household internet needs at 10–16 watts. Single-band routers use less power but are inadequate for modern streaming and multi-device households. Compact Wi-Fi 6 models from Eero and TP-Link’s compact lines are particularly energy-efficient.
Does a router use electricity even when no one is home?
Yes — a router consumes electricity continuously regardless of whether any devices are connected or using the internet. The consumption is slightly lower during complete idle periods but remains close to the operating wattage because the router maintains its networking functions at all times.
How much does a gaming router cost to run annually?
A typical gaming router consuming 28 watts costs approximately $39 per year at the national average electricity rate of $0.16/kWh. A high-end gaming router at 45 watts costs approximately $63 per year. For the complete annual cost calculation framework, see our Router Power Consumption complete guide.
Is a Wi-Fi 6 router more energy-efficient than Wi-Fi 5?
Generally yes — Wi-Fi 6 routers often consume comparable or slightly less power than older Wi-Fi 5 routers of equivalent capability, because the Wi-Fi 6 standard includes improved power management features. Comparing a Wi-Fi 6 router to a Wi-Fi 5 router of the same performance tier, the Wi-Fi 6 model is typically more energy-efficient per unit of throughput delivered.
