Set the alarm for 9:58 p.m.

Web alarm clock for 9:58 p.m.

You are watching the clock while your rechargeable lamp waits beside an outlet, ready to be charged before a scheduled brownout. Set this alarm for 9:58 pm so the last check does not slip past you. With 10:00 pm close behind, you can confirm the plug is secure and keep the lamp where it will be easy to find if the lights go out.

Your lamp reminder needs the browser to stay active enough to sound at the appointed minute. You may switch to another tab while waiting, but some phones restrict activity in a page left in the background, especially when battery-saving settings take over. If you close the page or let the phone sleep, the lamp alarm may stay silent, leaving the charging check undone. Keep this page open in the foreground, leave the screen awake, and make sure the volume is audible.

While waiting for the lamp alarm on a humid Philippine evening, place the unit indoors where air can circulate around it rather than beside an open window. Damp outdoor air at 9:58 pm can enter quickly, particularly during the rainy season. Keep the charging cable and socket dry, clear fabric away from the lamp, and use the final moments before 10:00 pm to check that nothing covers its vents.
