How Much Power Does a 4G Router Use?
A typical 4G LTE router draws somewhere around 3 to 12 W while it is running, depending on the model, the signal at the site, how many devices sit on it and how hard the radio is working. Outdoor and industrial units usually sit above that, particularly when they carry a second radio or a heater. For a solar point the wattage is only half the answer, because the router never stops: at 8 W it takes 192 Wh out of the system every single day, before conversion losses and before the camera on the same mast is counted at all. A weather station puts a logger and a sensor set on that mast, and a station’s uplink share runs the same argument with a smaller radio in it.

Q: How much power does a 4G router use?
A: Plan with roughly 3 to 12 W for a 4G or LTE router, higher for outdoor and industrial units, and higher again where the signal is poor. Treat that as a planning estimate rather than a specification for your unit, because 4G router power consumption varies with the radio, the traffic and the number of clients. The figure printed on the power supply is an output rating, which is a ceiling rather than the running draw, so the number worth carrying into a sizing calculation comes from one measurement at the plug.
The Bands to Plan With
These are estimates for early planning, not fixed figures that apply to every unit on the market. Each row tells you where to confirm the number before you commit to a system.
| Device at the point | What to assume at first | Where to confirm it |
|---|---|---|
| Indoor 4G LTE router | About 3–8 W | The model’s own specification, then one measurement under load |
| Router with Wi-Fi serving several clients | Assume the upper end, then measure | Your meter, with the clients connected that will really be connected |
| Outdoor or industrial LTE unit | Above the indoor band; do not reuse an indoor figure | That model’s specification, especially with a heater or a second radio |
| PoE injector or network switch | Count it as its own load | Its own rating, keeping the device draw apart from conversion loss |
Signal conditions and radio activity both move the figure, so a point in a fringe area can sit well above the band you assumed. That is one of the reasons a single measurement beats every table, including this one.
Why Daily Energy Matters More Than Router Wattage
Take a router drawing 8 W continuously. It uses 192 Wh a day, which becomes 1,344 Wh across a week and 5,760 Wh across 30 days. Those figures describe what the router consumes. They do not tell you how many days a battery will carry it, and reading them that way is where sizing goes wrong. A camera that records around the clock joins that daily figure rather than sitting beside it, and what continuous recording adds to a router point runs the two together.
The usable energy quoted for these systems is stated at 12 V nominal, with the reserve the system keeps in hand and the conversion loss already taken off. On that basis the 40 Ah battery holds about 326 Wh, the 60 Ah about 490 Wh and the 120 Ah about 979 Wh. Two things follow from it. A load of that size takes a large share of the smallest reserve before a camera is added. And the reserve only stays available if the panel puts back what the load takes out. When the answer is no, the not-charging checklist runs from panel surface to output connection.
So the useful question at a router point is not whether the daily figure fits inside the battery. It is whether the panel replaces a day’s consumption on the days the site actually gets. A run of grey days draws the reserve down, and the reserve is what carries the point until the sun returns. That is why 4G router power consumption per day has to be read alongside panel output and the worst month at the site rather than on its own.
The camera side of the same sum, including why an adaptor rating is not the load, is set out in camera power draw.
How to Get Your Own Number
Every band on this page is an assumption until you measure, and that is the real answer to how much power does a 4G router use at your site. Put a DC meter between the power source and the router, run the point the way it will run in service, and read the current while traffic is moving. Multiply volts by amps for watts, then write the result inside the enclosure door. That note saves the next person the same afternoon.
Measure under load rather than at idle, and measure at the site rather than on a bench. A router holding a weak link draws more than the same unit in a city office, and the difference stays invisible until the battery goes flat three days into a grey spell. If the supply states 12 V at a given amperage, read that as the ceiling it will not exceed rather than the figure it uses, for the same reason a camera adaptor rating overstates a camera.
The Ceiling Is an Output Rating, Not a Promise
Every system in this range delivers DC 12 V with a ceiling of 5 A, which is 60 W at that voltage. That 5 A is the limit for the output as a whole, not a figure that repeats at each socket, so two devices running from the same feed share it between them. A point stays inside the rating while the combined continuous draw sits below it with some room left for peaks.
Staying under 60 W keeps you inside the output rating. It does not, by itself, mean the point runs day and night. The battery sets how long the point can keep going, panel output sets how quickly the reserve is refilled, and weather, cable loss on a long run and start-up peaks all draw on that same reserve. Keep the two ideas apart when you specify a point: the ceiling describes what the output can deliver, the energy budget describes how long the site stays up. Most sizing mistakes come from mixing them.
Where the link is the whole job rather than an accessory to a camera, the arithmetic shifts but the ceiling does not, and a 4G base station point works through that case. Where the uplink serves a coverage point rather than a carrier site, what a site hotspot draws is the same arithmetic at its smallest. A bridge radio on the same feed is a third line of that account, and the load list for a bridge link adds it before any camera is counted.
Which Solar Power System Fits Your 4G Router?
All four models provide a DC 12 V output with a maximum rated current of 5 A. What changes between them is panel capacity, battery storage and how the system mounts.
| Model | Solar panel | Battery | Output limit | Typical application at the point |
|---|---|---|---|---|
| YO-M8040 | 80 W | 40 Ah · about 326 Wh usable | DC 12 V / 5 A | A light point close to home, where the kit has to stay small and go up quickly |
| YO-P12060 | 120 W | 60 Ah · about 490 Wh usable | DC 12 V / 5 A | The usual choice where a router and a camera share one mast at a mid-latitude site |
| YO-P12060-T | 120 W | 60 Ah · about 490 Wh usable | DC 12 V / 5 A | The same load where no wall is within reach and the mast has to carry everything |
| YO-P240120 | 240 W | 120 Ah · about 979 Wh usable | DC 12 V / 5 A | A heavy combined load at one point, or a site with long stretches of low sun |
Panel and battery figures are the published ratings of the four models, and the usable energy column follows the basis described above. How far that reserve carries a given point depends on the total draw, the panel’s daily input and the sun the site gets, so read the last column as a starting point for a conversation rather than a finished selection. Sizing solar power for a 4G router is a load calculation first and a product choice second.
