Dual Pro Battery Charger Repair

Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet? 

Every mobile phone, notebook, and tablet seem to come with their own charger.  If you’re like me, you’ve probably compiled a number of chargers over the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this guide, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly unique to the device they include.  However, there may be some generic chargers which boast the capability to be interchanged between laptops.  This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage for your device.

Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the same voltage, but may draw various amps.  I will explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.

In order for a charger to be used on another device, it’s essential that the plug  of the charger (the”head”) fit securely into the charging port of the device.  Micro USBs are the same across the board so far as charging heads, while notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is just 1 part of the equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you’ll get a tag with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the bottom of the charger, in which it would meet the wall.  For the device you are attempting to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw into the apparatus, or how much is being”pushed” into the apparatus by the charger.  A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” to the device, or how much electricity is used by the device.  The quantity of volts won’t ever change, but the amount of amps that the system pulls may change based on how hard the device is working.  The number that you locate on the battery that came with your device are the maximum amount of amps that may be pulled by the device.  The number found on the charger is how many amps can be pulled at once. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot support the amp requirement, it can burn out the power supply and kill the apparatus.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equivalent ).  *Website Note: if you have an older device, it might not work with USB interfaces that employ the newest Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts. 

An interesting point to note is all chargers provide a higher voltage than the batteries they charge.  That is pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  If you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power needs of the apparatus, or aren’t built to maintain a steady flow securely.  Overall, it’s best to stay with the charger designed for the device you are using.

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to help you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device.  Be sure to follow exactly what we said and you should be ready to go!
