Cordless Table Lamps: Charging, Runtime and Everyday Care

Cordless describes use without a power cable attached. Rechargeable describes a battery that can be charged again. USB-powered can describe a lamp that needs its cable attached while operating. Do not assume these terms mean the same thing when comparing listings.

Our $49.99 cordless rechargeable mushroom lamp has a built-in 1800 mAh battery and USB-C charging. It is different from the separate USB-powered mushroom lamp in our catalog. Use the exact product name and specification so you order the power type you need.

Check the input and power-supply instructions before charging. USB-C names the connector, not every electrical requirement. Use the recommended equipment and do not assume a wall adapter is included simply because a cable is supplied.

The rechargeable mushroom lamp includes one USB charging cable and has an approximate full-charge time of three hours. Charge on a dry, stable surface following the instructions. Do not assume continuous plugged-in operation or use while charging is supported unless those instructions say so.

A larger battery capacity does not translate into a universal number of lighting hours. Power demand varies by lamp and brightness. When comparing an up-to runtime claim, check the dimming setting and test conditions behind it.

We do not have a verified runtime for our 1800 mAh mushroom model. We therefore do not promise a full night, several evenings or a specific hour count. If uninterrupted light is essential, choose a model with documented operating time at your required brightness or consider plug-in lighting.

Touch dimming controls intensity. The three light tones on this model are 3000K warm, 4500K neutral and 6000K cool. Use the setting that looks comfortable in your room, while keeping enough light for the activity.

Kelvin describes light appearance; lumens describe output. A cooler tone is not proof of more usable reading light. Our model has no verified lumen specification, so we recommend it for indoor ambient and accent use rather than as a dedicated reading lamp.

The lamp is approximately 10 × 16 cm, or 3.9 × 6.3 inches. Check the base against the tabletop or shelf and leave space around it. Keep it away from drinks, curtains and positions where it is likely to be knocked over.

Portability does not establish weather resistance. We do not have a verified outdoor IP rating for this model. Choose a lamp specifically rated for the environment if you plan to use it outdoors or in damp conditions.

Follow the supplied instructions for cleaning and charging. Avoid exposing the electronics and charging port to moisture, and do not use damaged charging equipment. If the lamp or battery shows damage or unusual behavior, stop using it and contact support.

Keep the product name and order information available when asking a question. Photos of the lamp and the relevant issue can help support identify what you are describing. Do not open or modify the battery housing to diagnose an issue.

The current supplier-matched finishes are Gray, Light Gray, White and Black. Select the finish on the product page and inspect its matching supplier image. Older blue and red photographs do not describe the current variants of this model.
