Method 5: Using a DIY charger

If you are a physics enthusiast or techy, you will surely want to try this thing. So what’s a DIY charger? In tech terms, DIY is the acronym for ‘Do It Yourself’. A DIY charger is nothing but a charger made by you from scratch. So, let’s have a quick synopsis of how to use a Lithium-ion DIY battery and use it to charge a stylus yourself.

  1. 1) DIY is a mini charger. Just provide it with a 9-12 volts DC energy source.
  2. 2) In the USB port, connect the cable.
  3. 3) Connect the other end to the stylus pen.
  4. If the charging starts, then your DIY charger is working successfully. If not, check for loose connections.
  5. If the DIY charger becomes too hot, disconnect the charger. Try using low power in that case.

Too powerful batteries might cause the DIY charger setup to burst. Always use the optimum power batteries as instructed.

Method 6: Surface Pro-X Signature Keyboard

For this, you need to get a ‘Firmware update‘ beforehand.

  1. Put the pen on the charging surface of the Signature keyboard. The pen might also realign itself under the magnetic influence.
  2. Click “Start”.
  3. Find “Settings”.
  4. Look for “Windows Updates”.

Technical perks never come without precautions. Mishandling small things like a USB cable, a battery or digital pens can land you in trouble. There are some needful precautions you should keep in mind while charging your stylus/ digital pen. Especially when you are not using the pen’s charger and trying other alternatives for the charging aspect. Let’s run over them right away:-

  1. Never charge more than one device simultaneously. You might cause an overload in the circuitry. This will damage all the connected devices.
  2. Try not to use the pen while charging. You might weaken the battery’s power drawing capacity. Better unplug the charger and use it for a while if it is urgent.
  3. Keep in mind the brand factor. If you lose the charger of your stylus, never attempt to use any charger which comes with other brands.
  4. Check the time after you are leaving the pen on charge. Long exposure to power might cause the battery to burst. No one would like that for sure.
  5. Check for worn-out cables or loose connections. In most cases, this has caused severe circuitry malfunction ending the pen’s lifetime.
  6. Don’t touch the pen or the ports with wet hands. You might get a shock. 
  7. Check the plug’s polarity. Don’t interchange the polarization or mess with it. The whole experiment might fail.
  8. Never disassemble the stylus while charging.
  9. Try to use an input supply ranging between 100-200 volts 5 amperes.
  10. Use authorized adapters and USB cables. An unauthorized product, if found faulty, might not benefit you. 
  11. Keep flammable materials away from the power source. Putting the charging setup on flammable things can cause overheating and fire.
