I'd like to speak to someone about a mortgage http://ziplinegear.biz/where-can-i-do-my-essays/ article critique essay You can certainly try, and you cannot normally damage a device by connecting it to a USB mains charger designed for something else (unless it is faulty or very badly designed). But as usual there are a few ifs and buts. Some chargers, and the USB ports on some computers and laptops cannot supply sufficient current, or they do not work because the device only functions with manufacturer-approved chargers. There are two styles of USB device connector in common use, Mini plugs, and the newer and slimmer Micro plugs, which have become the industry standard. They are not compatible so never force a plug if it doesn’t fit. The other fly in the ointment is Apple, which uses proprietary ‘dock’ connectors on its products. There are issues with the way lithium-ion batteries are charged when at or near to being fully discharged. For best results and to prolong their lives they should be trickle charged to begin with, before going on to receive a full charge, so if you regularly flatten your gadget’s battery it is a good idea to stick with its own charger. Your best chance of finding of finding a mains charger that will work with as many devices as possible is to check its current rating and 1.5 amps (1500mA) is usually enough for most pocket size gizmos, cameras, smartphones and so on. Tablets, iPads and power-hungry devices like external hard drives generally need something with a bit more oomph, typically 2.1A or higher.
