<p>Vapes, e-cigarettes, spare lithium batteries and power banks are allowed through Bristol Airport security and on board your flight, but only in hand luggage, never in a checked or hold bag. Power banks up to 100 watt-hours (Wh), which covers almost every consumer model, need no airline approval; above that, different limits and rules apply. Prices and rules checked 2026.</p>
<h2>Can you take a vape or e-cigarette through Bristol Airport security?</h2>
<p>Yes. Vapes and e-cigarettes are treated as battery-powered electronic devices, and like laptops, phones and other electricals, Bristol Airport's own <a href="https://www.bristolairport.co.uk/at-the-airport/security/">security guidance</a> says these should be kept inside your hand baggage for the X-ray screening rather than removed and placed loose in a tray. The device itself, and any e-liquid it contains, must travel in your cabin bag. It cannot go in checked luggage, because UK and international rules ban devices containing lithium batteries from the hold, since a battery fault in the cabin can be seen and managed by crew, while the same fault in the hold cannot.</p>
<h2>Why vapes can't go in hold luggage</h2>
<p>The restriction isn't specific to Bristol, it applies at every UK airport and on every UK-departing flight. Lithium batteries, including the small cells inside e-cigarettes and disposable vapes, carry a risk of thermal runaway, a fault that causes rapid overheating and can lead to fire. Cabin crew are trained to respond to this in the passenger cabin; in the hold, a fault can go undetected until it's too late. That's why the device, and any spare batteries for it, must stay with you in the cabin rather than in a bag you check in.</p>
<h2>Packing a vape for security</h2>
<ul>
<li>Keep the device in your hand luggage, not your pocket, so it goes through the X-ray scanner like other electronics.</li>
<li>If your device has a refillable tank, empty it before you travel where possible. Changes in cabin pressure can cause partially full tanks to leak into your bag.</li>
<li>Store any e-liquid you're carrying separately under Bristol Airport's liquids rules, since e-liquid counts as a liquid for security purposes. See our <a href="https://bristolairportguide.pages.dev/articles/bristol-airport-liquids-100ml-rule">liquids rule guide</a> for the current container limits at Bristol's security lanes.</li>
<li>Disposable vapes are packed the same way as refillable devices: hand luggage only, never checked.</li>
</ul>
<h2>Spare batteries and power banks: what's allowed</h2>
<p>Spare lithium batteries and power banks, whether for a vape, a phone, a camera or a laptop, follow watt-hour (Wh) limits set by aviation safety regulators (ICAO/IATA guidance, reflected in UK Civil Aviation Authority rules) and applied by individual airlines. The table below sets out the general baseline.</p>
<table>
<tr><th>Battery capacity</th><th>Rule</th></tr>
<tr><td>Up to 100Wh (roughly a 27,000mAh power bank or smaller)</td><td>Allowed in hand luggage without asking your airline in advance</td></tr>
<tr><td>100Wh to 160Wh</td><td>Allowed in hand luggage only with your airline's prior approval, and usually capped at two batteries</td></tr>
<tr><td>Over 160Wh</td><td>Not permitted on passenger aircraft, in the cabin or the hold</td></tr>
</table>
<p>To work out the watt-hours of a power bank from its printed mAh rating, multiply the mAh by the voltage (almost always 3.7V for a single lithium-ion cell) and divide by 1,000. A 20,000mAh power bank, for example, works out at roughly 74Wh, comfortably under the 100Wh threshold.</p>
<h2>How many power banks can you carry?</h2>
<p>Under the international aviation safety guidance airlines have been rolling out since March 2026, most carriers now cap passengers at two power banks or sets of spare batteries per person, ask that they not be stored in the overhead locker (keep them in a seat pocket or bag under the seat instead, so cabin crew can reach one quickly if it overheats), and prohibit charging a power bank, or using one to charge another device, during the flight. These specific limits sit on top of the underlying 100Wh/160Wh rules and can vary slightly by airline, so if you're travelling with more than one power bank or a larger-capacity one, check your specific airline's baggage policy before you fly from Bristol.</p>
<h2>What about laptops and phones with built-in, non-removable batteries?</h2>
<p>Devices like laptops and phones have their battery built in rather than carried as a spare, and these are allowed in hand luggage under the same principle: keep them with you, don't check them, and follow Bristol Airport's instruction to leave electricals like laptops accessible in your bag for screening rather than buried under other items.</p>
<h2>Where can you actually vape at Bristol Airport?</h2>
<p>This is a different question from carrying a vape through security. UK smoke-free law technically covers tobacco rather than e-cigarettes, but Bristol Airport hasn't published a separate vaping policy, so the safe assumption is that the same restrictions as smoking apply throughout the terminal. For the full picture on where smoking and vaping are and aren't permitted on site, see our guide to <a href="https://bristolairportguide.pages.dev/articles/can-you-smoke-at-bristol-airport-rules-explained">smoking and vaping rules at Bristol Airport</a>.</p>
