Charging and USB ports
Check the charging port type and whether you can use the lamp while it charges. Some plug-in lamps include a USB port for charging a phone; check its listed output if that matters to you.

Rechargeable batteries hold less charge as they age. Check whether the battery can be replaced and what the warranty covers. Charge with the cable or adapter the maker specifies. If the lamp or its remote uses coin or button batteries, keep spare and used batteries away from children.
