Hints from Heloise
Dear Heloise: When I get a new cell phone, I always write the brand and model number on the charger with a permanent-marker pen. Cell-phone chargers can have different voltages and currents, and marking the charger prevents me from accidentally plugging it into the wrong cell phone.
A bonus is that if I find that an older charger has the same output voltage, current and connector as my cell phone, I can store it in my suitcase, ready for travel. — Joe Swelnis, Richmond, Ky.
