How Does Battery Repair App Work

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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you are 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, laptop, camera, or tablet computer that is not the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  While some devices have chargers using a slightly different head or charging cable, these are the most common.

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

Micro USBs are theoretically designed to be interchangeable, and are standard in many smartphones, Android devices, and tablets.  Micro USB chargers typically have the same voltage, but may draw different amps.  I’ll explain this further later and how to know if the charger is safe to use (depending on its listed amps and voltage).

For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.

The Plugs Must Be The Same

For a charger for use 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 often specific to both make and model.  However, the plug fitting firmly is only 1 part of the equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you will get a label 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’re attempting to control, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.

Voltage is how much power the charger will draw in the device, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to around 5V, though a laptop can pull up to 25V.  A charger must equal the voltage required by the device.  This is important: drawing too high a voltage could short out the device and potentially even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” into the device, or how much power is used by the device.  The amount of volts won’t ever change, but the quantity 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 which can be pulled by the device.  If a unit is paired with a charger that cannot support the amp necessity, it may burn out the power supply and kill the apparatus.

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

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

Some devices might have their voltage listed with a plus/minus on it like this: 5v +- 5%.  If this is the case, you can 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 percent of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts. 

An interesting point to note is all chargers supply a higher voltage than the batteries that 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.  When you look at your vehicle, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the power requirements of the apparatus, or are not built to keep a steady flow safely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stick with the charger designed for the device you are using.

Now You Understand How to Safely & Effectively Swap Chargers

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