Nearly a third of Australian homes are rented. At the 2021 census, 30.6 per cent of occupied dwellings were tenanted. Every one of those households has the same lighting problem: the fittings are fixed, the wiring is not theirs to touch, and almost all lighting advice assumes otherwise.
Cordless rechargeable lamps exist to solve that, and they have quietly become one of the fastest moving categories in lighting. This is a guide to buying one that is worth owning.
Why they took over
We counted the Amazon United States best seller lists in August 2026. Rechargeable cordless models were 40 per cent of the top sixty table lamps and 73 per cent of the top thirty wall lights. On Amazon Australia the top of the table lamp ranking is dominated by rechargeable, touch operated, USB-C models between 15 and 40 dollars.
That is not a fashion. It is what happens when a light stops needing a socket, because the number of places a lamp can go multiplies overnight.
What the law actually allows you to do
This is the part that matters if you rent, and it is simpler than most people assume.
Hardwiring a light fitting is electrical work. Under AS/NZS 3000, the Wiring Rules, installing a fitting connected to the 240 volt mains requires a licensed electrician. In New South Wales, unlicensed electrical work carries penalties of 22 000 dollars for an individual and 110 000 dollars for a company.
Plugging an appliance in is not electrical work. Queensland's Electrical Safety Act says so in plain terms: electrical work does not include connecting equipment to an electricity supply by a flexible cord and a plug. A rechargeable lamp goes one step further again, because it charges from a USB cable and then runs on its own battery.
So a rechargeable wall light mounted with adhesive or two screws is furniture, not an installation. That is the whole appeal.

The five places they earn their keep
Beside a bed with no power point
The most common domestic case, and the one we treat in full in how to light a bedroom for better sleep. A bedside table on the far side of a bed is often two or three metres from the nearest socket, and the alternative is a cable across the floor. A cordless touch lamp removes the problem and gives you dimming at the same time.

A hallway or a stairwell
Sockets are rare in hallways and almost never at floor level, which is exactly where a night light needs to be. A rechargeable motion sensor unit mounts low, lights the floor rather than the eyes, and runs for weeks because it only draws power when something moves.

Under a kitchen cupboard
Benchtop lighting is the one place where a shadow is genuinely a safety issue, because the person standing at the bench blocks the ceiling light from the board they are cutting on. Under cupboard strips normally need wiring. A rechargeable bar with a motion sensor does not.

Outside, on a table
Alfresco dining in an Australian summer runs late. In Sydney the sun sets at 8.05 pm on 21 December, in Brisbane at 6.42 pm because Queensland does not change its clocks. A portable lantern on the table is the light that moves with the meal, and it needs no outdoor socket and no electrician.
Our guide to outdoor and solar lighting for summer goes further into this. If it is going outdoors, check the IP rating. The second digit is the water one: 4 covers splashing, 5 covers low pressure jets, 6 covers powerful jets. A lamp rated for indoor use only will not survive being left out through a storm.

When the power goes out
A charged lamp is a better blackout light than a torch, because it lights a room rather than a beam, and because it is already sitting where you need it instead of in a drawer.
On a balcony or a rented courtyard
Balconies almost never have an outdoor socket, and running an extension lead through a door is both ugly and a trip hazard. A rechargeable lamp is the only option that does not involve an electrician or a landlord conversation. In an apartment it is often the only outdoor light the tenant is allowed to add at all.

How to read the battery number
Battery capacity is quoted in milliamp hours, and on its own the figure means very little. The arithmetic that turns it into something useful is short.
Multiply the capacity in amp hours by the cell voltage, which is 3.7 volts for almost every lithium cell used in a lamp. That gives you watt hours. Divide watt hours by the power the lamp actually draws and you have the run time.
| Battery | Energy | At 1 W, low setting | At 5 W, full brightness |
|---|---|---|---|
| 2000 mAh | about 7.4 Wh | around 7 hours | around 1.5 hours |
| 4000 mAh | about 14.8 Wh | around 14 hours | around 3 hours |
| 10 000 mAh | about 37 Wh | around 37 hours | around 7 hours |
These are ceilings rather than promises, because no battery delivers its full rated energy and no driver is perfectly efficient. Take 70 to 80 per cent of the figure and you will not be disappointed.
The practical consequence is that the brightness setting matters far more than the battery size. A lamp advertised at 100 hours is quoting its lowest setting. The same lamp on full will do a single evening.
Charging habits that actually work
The failure mode of a rechargeable lamp is never the lamp. It is that nobody charges it. Three habits fix that permanently.
Keep one charging point for all of them, ideally a multi port USB charger on a shelf rather than a wall socket you also need for something else. Charge on a day of the week rather than when the light dies, because a flat lamp at nine in the evening is when you least want to deal with it. And buy lamps that all take the same cable, which in practice means USB-C on everything.
If a lamp is going to live somewhere awkward, such as under a cupboard or at the bottom of a stairwell, prefer a model where the light lifts off a magnetic plate. Carrying the light to the charger is easy. Carrying the charger to the light is how a lamp ends up unused.
Six things to check before you buy
- USB-C, not micro USB. Micro USB is obsolete and you will end up owning one cable for one lamp.
- Stepless dimming, not three fixed levels. Three levels always means the one you want is between two of them.
- Where the switch sits. Touch on the body or the base is reachable in the dark. A switch under the shade is not.
- Does it remember the last setting. A lamp that returns to full brightness every time you switch it on defeats the point of dimming it.
- Can it run while charging. Some cannot, and that turns a flat battery into an evening without a lamp.
- Mounting, for wall units. A magnetic plate that lets the light lift off to charge is worth more than a slightly better battery.

What they are not good at
Cordless lamps are not a substitute for a main light. A battery lamp bright enough to light a whole room would flatten itself in an hour, so nobody builds one. They are a second and third light source, and they are excellent at that.
They also introduce a chore. Every rechargeable light in the house is a thing that needs plugging in occasionally. Two or three is manageable, and it works best when they charge in the same place. Nine scattered around the house is a job.
Lastly, batteries age. Expect noticeably shorter run times after a few years, which is a reason to prefer lamps where the light is genuinely useful on the low setting rather than only on full.
Where to start
If you are buying one, buy the bedside lamp. It is the light you use every day, the position most likely to be short of a socket, and the one where touch dimming changes the room. If you are buying two, add a motion sensing light for the hallway.
