Here is the most popular question about new technology, and the products we are encouraged to buy. ” Why does every new item need a new style of charging cord? ” Even gadgets of the same make seem to require you to purchase a new charger, as the older style doesn’t work on the new model.
The answer is only too obvious, but it raises the question, aren’t these big businesses making plenty of money, selling us ” new and improved ” gadgetry? I am constantly amazed with all of the changes that are made to virtually the same products. There is no reason to change the simple things, like charging cords.
Most of the new tech items are using the USB port type chargers, and have the ability to recharge from a laptop, or a wall mount type charger, although the basic amperage may be different. Usually there is a safety feature installed to prevent your device from accepting too much voltage.
All of the phones use the same voltage batteries, but the battery designs are different, so you can’t use the old one you have. That way you have to buy a new one, and that generates more revenues for the parent company. Most of the laptops, and notebooks use a battery that ranges from 5 volts to 20 volts, depending on the device.
Almost all of the phones use a 3.6 volt battery. For those not in the know, it takes more voltage than what the battery voltage is, to fully charge. That is why chargers for your phone say they deliver 5 volts, while the battery is only 3.6 volts.

Here’s how to charge any battery enough to keep doing the important stuff.
Fact 1: All past and future rechargeable batteries can be safely trickle charged if you don’t overcharge them. Trickle means low current, like half an amp for an average camera or phone battery.
Fact 2: Small incandescent bulbs such as flashlight bulbs and christmas tree mini lights make great current regulators.
You can plug any USB device into any USB cable and into any USB port, and nothing will blow up — and in fact, using a more powerful charger should speed up battery charging.
