It is often the first question people ask when choosing a night light: should you keep it permanently plugged into an power point, or opt for a battery-powered rechargeable model?
Both formats each have their advantages, and the right choice mainly depends on where the night light will be placed and how you plan to use it every day.
Here is how to decide, featuring real models and their prices.

- Plug in night lights: simplicity and reliability
- Rechargeable night lights: placement freedom
- Operating cost over time

The two operating principles
A plug in night light stays plugged in permanently and operates as long as power is present, without ever running out of battery. A rechargeable night light stores energy and works autonomously, but requires regular recharging.
Two answers to different needs
The plug-in format suits a fixed, permanent use; the rechargeable format is better suited for mobility, moving from one room to another or while traveling.
Neither is objectively superior: they are two technical solutions for different needs, and the best choice mainly depends on your home and your routine.
Plug in night lights: simplicity and reliability
Once plugged in, a plug in night light requires no attention at all: no recharging to plan for, no risk of finding it turned off in the middle of the night due to a dead battery.
Ideal for a fixed and permanent spot
This format is perfectly suited for a bedroom where the night light always stays in the same place, near the cot or in the hallway, without needing to be moved.
It is also the simplest format to hand over to a child who might not necessarily remember to recharge it themselves: it is always ready, without special supervision from parents.
Rechargeable night lights: placement freedom
Cordless and free from the constraint of a nearby power point, a rechargeable night light can be placed wherever you like, even far from any power source.
The right choice to follow a child from room to room
This format becomes particularly useful for accompanying a child moving between rooms, or for taking the night light along on weekends or holidays. Our article How to choose the right rechargeable night light? details the battery life and charging criteria to check.
It also suits homes where power points are scarce or already taken by other appliances, a common limitation in well-equipped children's bedrooms.
Operating cost over time
A plug in night light draws a small amount of electricity continuously, but its cost remains very low for a low-power device. A rechargeable night light draws nothing between charges, but its battery loses capacity over time.
A compromise rather than a clear winner
Over several years of use, neither format is significantly more economical than the other: the real difference comes down to convenience of use, not the electric bill.
One point to watch with the rechargeable option: battery capacity gradually declines, typically after one to two years of daily use, slowly reducing the initial run time.
Can you have both formats at home
Nothing prevents you from combining both: a plug-in model for the master bedroom, a rechargeable model for trips or overnight stays at the grandparents'.
Matching the choice to each room rather than the whole house
This approach avoids having to pick a single universal format and lets you optimise each use: reliability for a fixed spot, flexibility for occasional travel.
Criteria to compare before buying
Here are the four benchmarks to decide between the two formats.
| Criterion | Plug in night light | Rechargeable night light |
|---|---|---|
| Reliability | Runs continuously, no recharging | Depends on battery level |
| Mobility | Fixed, near an power point | Moves freely |
| Maintenance | None | Regular recharging |
| Budget | From $78.99 | From $78.99 |
Our plug in and rechargeable night lights
My Night Lights offers both formats, starting at $78.99.
A plug-in model, simple and reliable
The PlugLuz LED plug-in night light, at $78.99, plugs directly in and stays lit continuously without ever needing a recharge.
A rechargeable model, to follow your child everywhere
The PearTouch baby pear night light, at $88.99, recharges via USB-C and is easy to carry from room to room thanks to its compact shape. To compare more models, the Plug in night lights collection and the Rechargeable night lights collection bring together all designs for each format.
Both models are also available in several colours, making it easy to coordinate both formats if you choose to furnish multiple rooms in the house with the same night light style.
Mistakes to avoid
Certain choices made without considering real-life use end up disappointing once the night light is set up.
Three frequent pitfalls
Choosing a plug-in model for a room far from any power point, opting for a rechargeable model without checking the advertised battery life at low brightness, or insisting on a single universal format for every use around the house: three simple mistakes to avoid before purchasing.
Frequently asked questions
Which format is more reliable, plug-in or rechargeable?
The plug in night light remains the most reliable over time, since it does not depend on any battery level. The rechargeable night light simply requires remembering to recharge it regularly.
Does a rechargeable night light consume more energy than a plug-in model?
No, rather the opposite: it consumes nothing between charges, unlike a plug-in model that stays connected continuously, although the difference remains minimal on the electric bill.
Can you use a plug-in night light without a nearby power point?
No, that is precisely the limitation of this format: without an accessible power point near the desired spot, a rechargeable model becomes the only practical option.
Do you have to choose only one format for the entire house?
No, nothing prevents you from combining both: a plug-in model for a fixed location, a rechargeable model for travel or nights away from home.
Which format is best for a newborn?
Both are suitable, depending on the bedroom setup. A rechargeable model becomes useful if you move with baby from room to room during nighttime feedings.
In summary
Between a plug in night light and a rechargeable night light, there is no universal winner: the plug-in format wins on reliability and simplicity for a fixed spot, while the rechargeable format wins on placement freedom for mobile use. The right choice depends primarily on where the night light will be placed.
