How To Fix Hybrid Battery

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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you have probably compiled quite a few 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 article, we’ll focus 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 may be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage for your device.

Micro USBs are theoretically 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 different amps.  I will explain this further later and how to know if the charger is safe to use (based on its listed amps and voltage).

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

The Plugs Must Be The Same

In order for a charger to be used on a different 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 as far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting securely is just 1 part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A).  For notebook 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 found at the base of the charger, where it would meet up with the wall.  For the device you’re 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 just how much is being”pushed” into the device by the charger.  A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” into the device, or how much electricity is used by the device.  The amount of volts will never change, but the quantity of amps that the system pulls may change based on how hard the device is working.  The number that you find on the battery that came with your device are the max amount of amps which can be pulled by the device.  The amount found on the charger is how many amps can be pulled at once. If a unit is paired with a charger that cannot support the amp necessity, it may burn out the power source 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 ).  *Website Note: if you have an older device, it may not work with USB interfaces that use the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Isn’t 5v…

Some devices may have their voltage listed with a plus/minus on it like that: 5v +- 5%.  If this is the case, you can 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.  So 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 higher than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries they charge.  That is pretty much how they operate.  There has to be a voltage differential to produce the necessary current flow in the correct direction 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.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, especially cheap knockoffs, is that they frequently don’t support the energy requirements of the apparatus, or aren’t built to maintain 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 Know 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 come with your smart phone, notebook, camera, tablet, or other device.  Be sure you follow what we said and you should be good to go!
