45 products

Looking for good quality vape accessories to keep your kit running smoothly? Whether you need a spare battery, a new charging cable, or replacement glass for your tank, having the right vaping accessories on hand makes all the difference. In this guide we walk you through some of our most popular e cigarette accessories, explain what each one actually does, and help you figure out which one is right for your setup. No fancy jargon, just straight talking advice. Let's get into it.

Quick heads-up: Since 1 June 2025, UK regulations require all vapes to be rechargeable and refillable. Having the right accessories — spare batteries, charging cables, and replacement glass — is more important than ever for keeping your device running legally and reliably.

 

🔋 Battery Safety — Don't Skip This!

18650 batteries are powerful and need proper handling. Follow these simple rules:

  • Never carry loose batteries in your pocket with keys or coins — use a protective case.
  • Always use a proper charger — not your phone charger.
  • Replace damaged batteries — if the wrap is torn or the battery is dented, stop using it immediately.
  • Charge batteries on a non-flammable surface and never leave them unattended.

Avoiding these issues is simple with the right care and quality accessories.

Which Vape Accessory Do You Actually Need?

Not sure which pick suits you best? Let's break it down in plain, simple terms so you grab the right thing the first time round, instead of guessing.

 

What This Category Is Actually About

The vape accessories category covers everything that keeps your main device running behind the scenes, rather than the device itself. That means batteries, charging cables, and replacement glass — the small parts that quietly wear out, get lost, or need swapping long before you would ever think about buying a whole new kit.

Think of accessories as the maintenance side of vaping rather than the exciting side. Nobody gets excited about buying a charging cable, but running out of a working cable, battery, or piece of glass can stop you vaping just as quickly as running out of e-liquid.

 

Choosing The Right Battery

Removable batteries are the accessory people forget about the most, yet they are also the part that fails the most often. An 18650 battery is not built to last forever, and after enough charge cycles it will start holding less charge, heating up faster, or draining unusually quickly.

When picking a battery, two numbers matter more than anything else: capacity (mAh) and discharge rate (amps). Higher capacity means fewer charges throughout the day. Higher discharge rate means the battery can safely deliver more power — important if you vape at higher wattages.

 

Choosing The Right Glass

Replacement glass is tank specific — a Geekvape Z Max glass will never fit a Vaporesso iTank, and vice versa. Always check your exact tank model before ordering. Most tanks now offer a bubble glass option alongside standard straight glass. Bubble glass has a rounded, wider profile that holds more e-liquid — meaning fewer refills throughout the day.

 

Why A Spare Charging Cable Matters More Than You Think

A working charging cable seems like such a small thing until you cannot find one and your battery is sitting completely empty. Most modern devices use USB-C charging, so it is worth keeping at least one spare cable in your bag, car, or at your desk.

 

Matching Accessories To How You Actually Vape

  • Battery drains faster than it used to? Go for the AWT IMR 18650 Pack of 2 — having a spare charged and ready means you are never caught out halfway through the day.
  • Tank glass cracked or gone cloudy? Match the glass to your tank model rather than guessing. Vaporesso iTank owners → 8ml bubble glass; Geekvape Z Max owners → Z Max glass; Falcon 2 owners → Falcon 2 EU Glass.
  • Casual, once or twice a day vaper? Keep one spare battery, one spare cable, and the correct glass for your tank somewhere at home.
  • Heavy vaper? Keep a small stock of everything so a single worn part never leaves you without a working device.

 

Frequently Asked Questions — Vape Accessories

What are the most important vape accessories to keep as spares?

The most important e-cig accessories to always have as backup are batteries, charging cables, and replacement glass. Batteries drain unexpectedly, cables get lost or damaged, and tank glass cracks more often than people expect.

How do I know which 18650 battery is right for my mod?

It depends on how you vape. If you use higher wattage settings, look for a battery with a higher discharge rating like 40A, such as the AWT batteries. If you vape at lower wattages and want something dependable and long lasting, the Golisi G25 is a great steady option.

Can I use any USB cable to charge my vape mod?

Not always. Many vape mods use USB-C ports these days, so a proper vape charger cable made for vaping devices tends to work more reliably than a random cable lying around the house.

How often should I replace my vape batteries?

Most 18650 batteries last for several hundred charge cycles before performance drops off. If you notice your battery draining faster than usual, getting warm quickly, or not holding charge like it used to, it's a good time to swap it for a fresh one.

Why does my tank glass keep cracking?

Tank glass is usually made from regular glass or tougher pyrex, and drops or knocks are the most common cause of cracks. Bubble glass designs like the ones from Vaporesso and Geekvape are a bit sturdier and give you more juice capacity.

What is bubble glass and why is it different from normal tank glass?

Bubble glass has a rounded, wider shape compared to standard straight glass, which means it can hold more e-liquid without needing a bigger tank. This gives you longer vaping sessions between refills.

Are AWT batteries safe to use?

Yes, AWT batteries are a well known brand in vaping and are built with safety features suited for high drain devices. That said, like all removable batteries, you should only use a proper charger, avoid carrying them loose in pockets with keys or coins, and replace them if you notice any damage.

Is it worth buying batteries in packs of two?

If you use a dual battery mod or vape a lot throughout the day, buying batteries in pairs like the AWT IMR pack makes sense since both cells age at roughly the same rate. It also means you always have a backup ready the moment one battery starts running low.

What should I look for when buying vape accessories online?

Look for accurate specifications, clear pricing, and accessories made by known brands like AWT, Golisi, Geekvape, Vaporesso and HorizonTech. Buying genuine vaping accessories rather than unbranded copies means better safety and parts that actually fit your device properly.

Can replacement glass fit any tank?

No, replacement glass is made to fit specific tank models, so always check that the glass matches your exact tank before buying. For example, the HorizonTech Falcon 2 EU Glass only fits the Falcon 2 tank, while the Geekvape Z Max glass is made specifically for the Z Max Tank.
