Brits preparing to jet away on a long haul flight to the US are being warned of seven new strict bans on travel items. The Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) are warning tourists to pack several common items in their checked luggage as it could pose a safety risk on a plane.

The rules that come into effect immediately means travellers now pack several objects in their hand luggage. Most airlines have taken steps to ban travellers from carrying portable chargers in their checked suitcases, however the US is going a step further and banning seven types of battery-powered items from luggages.

Portable chargers are not allowed in checked luggage due to their risk of catching fire, which could prove deadly if they catch alight.

The CAA, responsible for regulating and overseeing aviation safety, says portable charges could cause an intense fire which couldn't be dealt with if it happened in the hold.

Spare laptop batteries which are uninstalled from the device are not allowed in checked luggage to the US. They must be carried in your carry-on baggage and must be protected from damage and short circuits.

Extra lithium-metal batteries are also prohibited in checked baggage. Separate loose lithium batteries must also be placed in their own seperate cover.

Seven items you can’t pack in checked bags when travelling to the US:

1. Power banks

2. Phone charging cases

3. Extra lithium-ion batteries

4. Extra lithium-metal batteries

5. Phone batteries

6. Laptop batteries

7. External battery packs or portable chargers

All of these items contain lithium batteries, which can overheat, catch fire, or explode under certain conditions.

FAA said in a statement: “When a carry-on bag is checked at the gate or at planeside, all spare lithium batteries and power banks must be removed from the bag and kept with the passenger in the aircraft cabin. The battery terminals must be protected from short circuit."
