6 Ways to Charge Vape Battery Without a Charger

How to Charge Your Vape Battery Without a Charger? (6 Ways)

Almost every vape you can buy aside from the disposable varieties will include a charger that enables you to recharge the vape’s batteries once they go dead. 

Whether it’s been misplaced, destroyed, or otherwise unavailable, though, there may be instances where your vape’s batteries have run out of juice, and you don’t have the appropriate charger available to bring them back to life. 

As the saying goes, necessity is the mother of innovation—and, with a little ingenuity, it is certainly possible to recharge most types of vapes even if you don’t have the right charger on hand. 

In this article, we’ll take a look at every possible option you have available for charging your vape without a charger.

#1 Use a Phone Charger

If your vape comes equipped with a micro-USB charging port—like many vapes do—then you are in luck. Micro-USB chargers are readily available, and most people will have at least one lying around the house somewhere.

Though the charger may not have been specifically designed for charging vapes, it will do the job nicely.

The bad news is that there are a lot of rechargeable vape models that do not feature micro-USB charging ports.

Box mods typically do have a built-in micro-USB charging port, but many rechargeable vape pens such as JUUL and Vuse vapes feature a unique charging port that won’t accept a micro-USB charger.

Likewise, not every phone charger you might be able to get your hands on is going to be a micro-USB charger.

A decade ago, micro-USB chargers were the standard for charging phones.

Today, though, many smartphone models come equipped with alternate charging ports such as lightning ports in the case of iPhones and USB-C ports in the case of many newer Android models.

If the stars align, however, and you happen to own a vape that features a micro-USB charging port as well as a micro-USB phone charger, then charging your vape with a phone charger is a simple and straightforward process.

#2 Use a Portable Power Bank

Portable power banks are products that enable you to charge devices on the go.

They are essentially large batteries themselves with included charging cables that allow you to connect them to a variety of different devices. 

So long as one of those cables is a micro-USB cable—and so long as your vape features a micro-USB charging port—then plugging your vape into a portable power bank should do the trick.

If your vape doesn’t seem to be charging when you plug into a portable power bank, though, it could be that the power bank itself has run out of battery.

Portable power banks don’t last forever and do eventually need to be recharged.

Some more expensive models will tell you how much power the power bank has left to give, but this isn’t the case with every model.

#3 Plug Your Vape Into a Desktop or Laptop

If you still have the appropriate charging cable for your vape but have misplaced the brick that the cable connects to, you won’t be able to charge your vape using a standard electrical outlet, but you can still charge it by plugging the cable into any device that features a USB port.

Laptops, desktops, and gaming consoles all feature USB ports that are perfectly capable of charging any vape as long as you have the right charging cable. 

Just note that if you are using a laptop not plugged in to charge your vape in this manner, it will cause your laptop’s battery to drain a little more quickly.

#4 Use an External Battery Charger

Rechargeable vape pens such as JUULs feature batteries that come wired to the device’s internal components and are not designed to be removed. 

For these devices, an external battery charger isn’t going to do you any good.

Most box mods, however, are powered by standard AA batteries that can easily be removed.

So long as your mod is equipped with rechargeable batteries—and most mods will come out of the box with batteries that are designed to be recharged—you can use an external battery charger to charge your vape’s batteries.

In fact, using an external battery charger is actually recommended for recharging a mod’s batteries since it can help preserve the battery’s life.

If you don’t happen to have one lying around, you can find an external battery charger.

This is a device that most vape shops will carry. 

Since external battery chargers are not vape-specific devices though, you should also be able to purchase them from almost any electronics store.

#5 Replace Your Mods Batteries

If you’ve lost the charger for a mod that features removable batteries, charging the batteries with an external battery charger isn’t the only option you have available. 

As we’ve already mentioned, most box mods are powered by standard AA batteries, though some may be powered by other types of batteries as well.

While the batteries that your mod comes pre-equipped with are likely to be the rechargeable variety, non-rechargeable batteries will work fine as well if you happen to have the right type available. 

Replacing your mod’s batteries each time they go dead isn’t the most economical solution, but it will work as a temporary fix if you are in a pinch.

Just keep in mind that if you do replace the batteries in your mod with standard, non-rechargeable batteries, plugging your mod back into its charger should you happen to find it again isn’t going to do anything. 

With this being the case, it’s a good idea to keep your mod’s rechargeable batteries on hand so that you can swap them back in again whenever you find your charger.

#6 Charge Your Vape With a DIY Charger

Here’s where things get a little tricky. If you have a charging cable available, but the charging cable doesn’t feature the right adapter that will allow it to be plugged into your vape, you can still make it work with a little DIY engineering.

The process for charging a vape in this manner differs depending on the type of vape you are charging, so we will look at how to use a DIY charger to charge three different kinds of vapes:

Yes, you read that right; even disposable vape pens that don’t feature a charging port at all can be recharged with this method.

No matter what type of vape you need to recharge, though, the first few steps of the process are the same.

Start by locating any charger that features a USB adapter.

Micro-USB chargers will work great, but for this method, other types of chargers such as USB-C and lightning port chargers will work as well.

As long as the other end of your charger is a USB adapter, you should be good to go.

Next, take a pair of scissors and snip off the end of the charger that is meant to be plugged into your phone or another device.

Then, using a craft knife or another sharp blade, cut away about two inches of insulation from the end that you snipped. 

This should expose both a red and black wire.

Once you locate these two wires, use your knife to cut off the insulation from them as well so that the copper wiring beneath is exposed. With all of this done, your DIY charger is ready for use.

To charge a JUUL using this DIY charger, you just need to insert the exposed wiring on the red and black wires into the outermost slots at the JUUL’s base.

If you look at the bottom of your JUUL, you should see four golden slots. 

Ignore the inner two slots and insert the exposed wires into the outermost slots, then place your JUUL on a flat surface so the wires won’t slip out.

To charge a disposable vape using your DIY charger:

  1. Unscrew the bottom cap of the vape using a pair of pliers and gently remove the vape’s internal components.
  2. Find the vape’s battery, then locate its positive and negative terminals. These should be marked with red (for positive) and black (for negative) coloring.
  3. Push the black wire against the battery’s negative terminal and the red wire against the battery’s positive terminal until your vape is charged or you run out of patience—whichever comes first.

While it is possible to charge the batteries in a box mod using this DIY charger, we’ve got to be honest and say that it is hardly worth the effort. 

To charge a box mod with this method, you will need to charge each battery individually by pressing the exposed wires to the battery’s positive and negative terminals, once again pressing the black wire against the negative terminal and the red wire against the red wire the positive. 

Since up to four batteries can power box mods and since their power demands are so high, charging a box mod in this manner has to be one of the most inefficient exercises known to man.

If you’re really desperate, though, it can be done.
