Charging your Vape Device Safely


Time to read 8 min

Wondering how to charge a vape? Need to know how long it takes to charge your new device? Want to know more about battery safety and handling the electrical components of your new vape kit? Read on for answers.

Your vaping device has been designed to be as safe as possible. Even though it is an electronic device, the manufacturers have tested it thoroughly for safety and prolonged use. However, when you don’t comply with the manufacturer’s instructions on how to charge a vape device and maintaining the safety of the device, you put yourself in jeopardy.

Here is everything you need to know about charging your vape and keeping your device safe.

How do you Charge Your Vape Device?

Charging your vape device is a simple task. Your e-cigarette will have a charging cable and port, which connect to a plug and a socket on the other end. The cable, usually a type C, connects to the device and the plug socket. This charges your device. The charging port on your e-cigarette may be on the bottom of the device. In thinner e-cigarettes the charging port will be inside the device and you will need to unscrew or remove the tank to get to it.

Let’s take an example. We are often asked how you charge an Elf Bar device, and how long you should charge it for. You can charge the range of Elf Bar reusable vape devices by taking the following steps:


  1. Begin by plugging in a universal USB-C cable. You will find the charging port located on the bottom of the device.
  2. Next, connect the USB end of the cable to a suitable USB power outlet. These are similar to the type of plug you use to charge your phone. You can also plug it into another device.
  3. As the Elf Bar begins to charge, you will notice that the glowing light indicator comes on. When this light goes off, the Elf Bar vape device is fully charged and ready to use.
  4. Do not try this with a disposable Elf Bar!

Remember - not all cables are type C, so check before you order a replacement. Some types of pod vaping devices charge via round battery packs. Others use a standard USB charging cable. If you have a preference, this is something to consider before you buy a starter vape kit.

Did You Know?

A convenient feature offered by modern bottom-charge port devices is that you can use them as they charge. This is one of the features that makes Elf Bar reusable vapes so popular.

How Long can I Leave my E-Cigarette in the Charger for?

You shouldn’t leave any of your electronics to charge overnight or unattended. The likelihood that something goes wrong may be small, but you have a better chance of dealing with it if you are awake and present. Unplug your chargers before bed. How else would you know your hair straighteners were switched off?

Charging your vape pen overnight isn’t inherently dangerous. The device will have a failsafe that stops it overheating or overcharging. Your device will use a steady trickle of electricity to stay at 100%. While this is minimal on your electricity bill, it’s not good for the battery. Much like the battery in a mobile phone, vaping devices use lithium ion. These battery types will eventually decrease in efficacy over time. They are good for a limited number of charges. When you charge overnight, you hit that target faster.

If you constantly must replace batteries on devices and you frequently leave them on charge overnight, unplugging will save you money. The following examples using popular devices might help you recognise how long you should charge your vape for.

How long to charge Elf Bar vapes?

Elf Bar are one of the most popular vape device brands on the market. After a blunder at the beginning of 2022, the company switched tactics. Once the most famous producer of disposable vape devices, Elf Bar are now producing Elfa Pro reusable pod kits using the same beloved flavours.

How long will it take to charge the Elf Bar pod kit? To determine the precise charging time for your rechargeable Elf Bar vape, it is important that you consider the requirements for your model specifically. This is because the duration of a full charge varies wildly between models. The variations come from factors like your Elf Bar’s mAh rating – which indicates the battery capacity of the vape device – and the initial level of battery power available when the charging process begins.

You should refer to the manufacturer’s instructions as to how long to charge Elf Bar vapes. This takes away the guesswork. The instructions for use, any warranty documents, and a list of your product’s specifications should all come in the box alongside your vape device.

Did You know?

If you cannot find the product specifications, then you can conduct an internet search for “How long to charge Elf Bar vape model xxxx,” where xxxx represents your individual model name or number. You can find most vape device documentation online.

How long does a Lost Mary take to charge?

Lost Mary vapes are part of the Elf Bar product family. When Elf Bar began upgrading to reusable devices, Lost Mary products followed. Originally renowned for disposable devices, this whole chain of brands are working towards making vaping more environmentally friendly.

How long will it take to charge the Lost Mary reusable vape device? These vape kits have varying charging times based on external and internal factors. These factors include:


  • The battery capacity
  • The model of the vape kit
  • Which type of charging cable you use
  • Which type of charging port you use – a high speed port will have faster results when charging your Lost Mary
  • The type of power source you use – charging through another device (such as your computer) is slower than charging by using a three point plug.
  • How much battery you have left when you begin charging.

It will take anything from 30 minutes to several hours to fully charge your Lost Mary rechargeable vape kit using a standard USB port on a low power source. For example, your Lost Mary vape could take hours to charge if the power source is the radio in your car or a spare port on your laptop. However, when you switch to a direct power source, Lost Mary vapes can charge within 30 minutes.

A high speed cable or port, a high power adaptor, or if you use a brand specific fast charger, can charge your Lost Mary in as little as 15 minutes. The downside of the fast charging capacity is that it may have a negative effect on your product’s lifespan.

As ever, the best way to get an accurate answer as to how long a Lost Mary vape to charge will depend on your model. See the manufacturer’s instructions and product specifications contained within the product’s packaging. As with the Elf Bar vape, you can conduct an internet search entitled “How long does Lost Mary vape model xxxx take to charge?” Again, “xxxx” represents the name or number of your model.

How long can I leave my E-Cigarette in the Charger for?

When you first purchase your vape, you should charge it until it is full. This can take up to 8 hours, depending on the device. After that initial charge, the time you need to leave it charging for will be lower. We do not recommend you leave it in the charger and go to sleep or leave the house. With that caution in mind, manufacturers maintain that e-cigarettes are safe to leave in the charger for extended periods.

Note: if your device is getting warm in the charger, bring it into our Milton Keynes or Stacey Bushes stores so we can advise you, or buy a replacement battery from our online vape shop.

Dos and Don’ts of Vape Charging

When it comes to charging your vape device:



  • Monitor how long you charge it for
  • Replace the battery if it runs down too quickly
  • Replace any parts with manufacturer approved replacements
  • Only use the correct charger assigned to your device

And Don’t:


  • Leave you e-cigarette in the charger indefinitely
  • Leave your vape charger plugged in when it’s not in use
  • Keep your charger anywhere near water or spillage areas
  • Use another device’s charger to charge your vape pen

Vape Kit Voltage Vs Wattage?

While the voltage of your device measures the speed of the electricity traveling around the circuit, the wattage is the sum of the volts plus the amps. The watt, therefore, is the rate of power flow in your vape device, while the voltage is the amount of power it uses to give you that output.

Should I buy a spare battery for my vape?

You have the option to buy a spare battery with your vape device if you wish. However, batteries that you stash in a drawer and forget about might not be as effective as a newly purchased one. Our advice is that you order a spare battery for your vape device if you suspect you are beginning to lose battery life. Otherwise, hold off on buying a new one until you need to.

How do you know when the vape device battery needs replaced?

If you are a light vape user, you should expect a fully charged battery to last you far longer than 24 hours. If you are a heavy vape user, you should expect to charge your device every day. If you find you suddenly need to charge your vape device after every use, you may need to replace it.

A full vape device battery lasts up to 150 puffs on the highest setting, depending on your device. If your e-cigarette starts to run out of battery before the limit specified by the manufacturer, then it’s time to replace the battery.

You should also replace your vape device battery if:


  • It is damaged in any way
  • The plastic wrap has come off it
  • It makes any kind of noise
  • It overheats
  • It displays signs of being faulty in any way
  • It doesn’t hold a charge

What’s mAh on E-Cig Batteries?

You may see a number on your battery that has mAh beside it. This is a unit of measurement. The rechargeable battery has a capacity to recharge at X mAh, which stands for Milliampere per hour.

A battery with a milliampere/hour of 1000 will last ten hours in a device that uses 100 milliampere/hour, and so on. Panasonic have more information on this.

How Long do you Charge Your Vape for?

If you take battery capacity, manufacturer’s instructions, and the battery level the kit already has within it, then you can work out the specific charging time for your device. If you use a standard charging port from a lower powered source, it can take anything upwards of 30 minutes to fully charge. If you use a high powered charging device and power source, your vape kit can charge in as little as 15 minutes at the cost of battery life.
