How To Fix 18650 Battery Wrap

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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you have 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 computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

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

Laptop chargers are fairly specific 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 may not be the optimal 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 (based 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 control the Lightning Connector.

The Plugs Must Be The Same

For a charger to be used 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 so far as charging heads, while laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only 1 part of this equation.

Somewhere on 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 located at the bottom of the charger, where it would meet the wall.  For the device you’re attempting 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 into the device, or how much is being”pushed” into the device 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.  This is important: drawing too high a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” into the device, or how much power is used by the device.  The quantity 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 find on the battery that came with your device are the max amount of amps which can be pulled by the device.  If a device is paired with a charger which can’t support the amp necessity, it may 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 faster charging (as long as the voltage is equivalent ).  *Site 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 Is Not 5v…

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

An interesting point to note is chargers supply a higher voltage than the batteries that they charge.  That’s pretty much how they operate.  There has to be a voltage differential to generate the necessary current flow in the proper 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.

The problem with knockoffs, especially cheap knockoffs, is that they often don’t support the energy requirements of the device, or aren’t built to maintain a steady flow securely.  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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be certain you follow what we said and you should be ready to go!
