How To Repair Laptop Battery At Home

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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you’re like me, you’ve probably compiled quite a few chargers through the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that isn’t the original manufacturer’s charger that came with the device?

Types of Chargers

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

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

Micro USBs are designed to be interchangeable, and are standard in many 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, including iPads and iPods. For older devices using 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 a different device, it’s important that the plug  of the charger (the”head”) fit securely into the charging port of the unit.  Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of this equation.

Determined by the power brick of the charger you will find a label with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, where it would meet up with the wall.  For the device you’re trying to charge, 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 in the apparatus, or just how much is being”pushed” into the apparatus by the charger.  A phone will usually pull up to around 5V, while a laptop can pull up to 25V.  A charger must equal the voltage needed 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 fast 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 quantity of amps that the device pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device are the max amount of amps which can be pulled from the device.  The amount found on the charger is how many amps can be pulled at once. If a device is paired with a charger that cannot support the amp requirement, 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 equal).  *Site Note: if you have an older device, it may not work with USB interfaces that employ the newest Battery Charging Specification.

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

Some devices might have their voltage recorded using a plus/minus on it like that: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that score is telling you is that the apparatus can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts.  This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or greater than the device’s listed amperage).

An interesting point to note is chargers provide a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There needs to be a voltage differential to produce the necessary current flow in the correct way to charge the battery.  If 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, especially cheap knockoffs, is they frequently don’t support the power needs of the device, or are not built to keep a steady flow safely.  Overall, it’s better to stick with the charger designed for the device you’re 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, laptop, camera, tablet, or other apparatus.  Be certain you follow exactly what we said and you should be ready to go!
