Set the alarm for 9:02 p.m.

Web alarm clock for 9:02 p.m.

Pause midway through your evening task at 9:02 pm and set an alarm so you remember to charge the rechargeable lamp before a power interruption. The reminder lets you return to what you were doing without repeatedly checking the clock. If charging should begin by 10:00 pm, this gives you a clear stopping point while the rest of the evening is still underway.

Because the lamp may be needed when the mains supply is unavailable, test the alarm sound now, while you can still adjust it. Set it for a nearby minute, confirm that you hear the signal from where you are working, then restore the intended time. Keep the browser alarm running in the foreground and prevent your phone or computer from sleeping; otherwise, the lamp reminder may stay silent and charging could start late.

While you prepare the lamp in the evening, avoid making a bright screen the main light in the room. Lower the display brightness to suit the surroundings, use warmer screen colours if your phone offers them, and place the lamp cable where you can connect it without staring at the display. At 9:02 pm, a brief screen check is enough; after confirming the alarm, put the phone face down so its glow does not compete with the room lighting.
