# USB vs Battery vs Plug-In Night Lights: Which Power Type Is Best?
> USB for flexibility, battery for portability, plug-in for brightness. Which power type suits which room, and why our lamps use USB.
Night lights come in three power types: USB, battery and mains plug-in. Each suits a different job. In short: USB for a decorative lamp that lives on a shelf, battery for something you carry around, plug-in for a simple low-level guide light in a socket. Here is the detail, and why every Artiviesta lamp runs on USB.
## Key facts
- USB night lights run from a phone charger plug, laptop or power bank and never need batteries.
- Battery night lights are portable but need recharging or replacement cells.
- Mains plug-in night lights are fixed to a socket and usually brighter than needed for sleep.
- For a decorative lamp that stays on a shelf, USB is usually the most practical choice.
## Night light power types
|  | USB | Battery | Mains plug-in |
| --- | --- | --- | --- |
| Power source | Charger plug, laptop, power bank | AA/AAA or built-in rechargeable | Wall socket |
| Placement | Anywhere within cable reach | Anywhere | Only at the socket |
| Running cost | Pennies a year | Batteries or recharging | Pennies a year |
| Runs all night | Yes | Depends on battery | Yes |
| Portability | With a power bank | Best | None |
| Best for | Decorative bedside/shelf lamps | Camping, travel, nightly carrying | Hallway guide lights |
## Why are USB night lights popular?
Because almost every home has spare USB plugs, and the same lamp works from a laptop or a power bank. There are no batteries to replace, the power supply is low-voltage, and the cable lets you put the lamp on a shelf rather than at socket height.
**Key takeaway:** **Direct Answer:** USB night lights work from any phone charger, laptop or power bank, need no batteries and can sit anywhere the cable reaches.
## When is a battery night light better?
When you need to move it: a light a child carries to the bathroom, a camping lantern, or a spot with no socket at all. The trade-off is recharging or swapping batteries. Note that a USB lamp plus a power bank covers many of the same situations.
## When is a mains plug-in night light better?
For a simple, permanent guide light at floor level in a hallway or landing, a small plug-in light with a dusk sensor is hard to beat. They are not usually decorative, though, and the light sits at socket height.
## Which costs least to run?
USB and mains LED night lights both cost very little: a USB lamp left on ten hours a night uses roughly 9 kWh a year at most, a couple of pounds. The full calculation is in our LED safety and running-cost guide. Disposable batteries are the most expensive option over time.
## Frequently Asked Questions
### 1. Is a USB night light better than battery?
**Direct Answer:** For a lamp that stays in one place, yes: no batteries to replace and it runs all night.
### 2. Can a USB night light run from a power bank?
**Direct Answer:** Yes. Any USB power bank will run it, which is handy in power cuts or away from a socket.
### 3. Do Artiviesta lamps need batteries?
**Direct Answer:** No. They run from any 5V USB socket, and the cable is included.
