How Do I Charge The Lumio Book Light Battery?

Lumio book lights are wonderful and charging them is as easy as pie. Once you know where the charging port is (it’s usually tucked away in the spine or base of the lamp) charging becomes a doddle.

First you need to find the charging port. This is usually located at the spine or base of the book-lamp. It may be hidden under a tiny rubber flap or even a magnetic cover. The port is usually mentioned in the documentation provided with the lamp or even in the small pocket that holds the cable. The cable provided in the box should have a corresponding port at the end, which is usually a micro-USB port or even a USB-C port (newer Lumio models).

Be sure to note the LED indicator on the charging port. Most Lumio models display a red or amber light when charging and turn green or cease to function when fully charged. The full charge time for a Lumio varies from model to model but typically charges within 2 to 6 hours and is best to allow a full charge for the first use before a long reading session.

Also, charging: try to keep it in a cool, well-ventilated place, and don’t let it go completely flat for too long. And never force the plug into the port. If it refuses to charge, try using a different cable/adapter, or just clean the port gently with a cloth. If all else fails, hold the power button for 10-15 seconds and it should reset itself. Just be careful not to overcharge it, or let the battery swell up, or make it get extremely hot. If any of those things happen, stop using it immediately and contact the seller. I keep mine on my bedside tray and it’s so quick and easy to charge and I know when it’s ready for my late-night reading.

Plugging in the lamp is short and easy. Locate the recharging port on the spine or bottom of the lamp (it is covered with a rubber grommet). Plug in the supplied recharging cable (micro-USB or USB-C) to a USB powered port (such as a wall wart or computer USB port). The lamp’s charging indicator light will display red/amber while charging and green or ceasing to glow when fully recharged. Recharging typically takes 2-6 hours depending on the degree of discharge of the lamp’s battery.

Here are a few more charging tips from my own experience. Turn the lamp off before you plug it in to charge up as fast as possible. Use a good adapter – it makes all the difference. If the USB cable doesn’t work, try swapping it with another cable (of the same type). Don’t leave your lamp in very hot places and if the battery becomes over-inflated and starts to get hot – STOP CHARGING IT straight away and get in touch with the support team. To date, mine has charged up just fine after long reads and then been ready to go for the next night – simple.

Plug in the Lumio book lamp. You can do this with the port located on the spine or on the bottom of the light. You will use the cable included with your light, which should be either micro-USB or USB-C. The other end of the cable goes into a USB port that is powered (like a wall adapter or a laptop USB port). Look for a small LED on the port of your light. It should be red or orange while the light is charging and green or unlit when the light is fully charged.

A couple of notes on battery health. It’s best to avoid letting a Lumio run completely dead for extended periods. And, to avoid any possible risk of fire, it’s best not to leave it plugged in in extremely hot locations. If your Lumio fails to charge, first try swapping out the cable and adapter – cables are far more likely to fail than the lamp itself. After charging, press the power button once to check the status LED, or check the current brightness level – occasionally a short press is needed to ‘wake’ up a Lumio that appears to be dead.

If you must know, it’s a rechargeable Li‑ion pack which should safely last through a few hundred cycles before slowly losing capacity. I keep a little charging station on my reading chair and periodically rotate the devices there through to keep them all fully charged and ready for when I need them.
