How big a power bank do I need for a UK power cut?

For keeping a phone alive through a short cut, a 10,000mAh bank giving around two charges is plenty. For a longer outage, or to share between family members, choose 20,000mAh or more, which realistically delivers three to four full phone charges after conversion losses.

Will a solar charger actually work in British weather?

Yes, but manage your expectations. A folding solar panel charges quickly in direct sunlight and slowly under cloud, so it is best used to top up a power bank on brighter days rather than as your sole source. Position it in full daylight, ideally facing south, for the best results.

Can I charge my phone from my car during a power cut?

Yes. Most cars have a 12V socket or USB ports that will charge devices, and a portable jump starter also works as a large power bank. Just never run the engine inside a closed or attached garage, as exhaust fumes contain deadly carbon monoxide.

Why choose lithium AA batteries over normal alkaline ones?

Lithium AA batteries hold their charge for up to ten years in storage, weigh less, and perform far better in cold conditions, where alkalines fade quickly. That makes them ideal for torches, head torches and radios you may not touch until an emergency arrives.

Do I really need a carbon monoxide alarm in a power kit?

If your backup plans involve any fuel-burning appliance, engine or portable stove, then yes. Carbon monoxide is invisible and has no smell, so an audible alarm is the only reliable warning. Fit one that meets BS EN 50291 and test it regularly.

Off-Grid Power Kit

When the power goes off, the first thing most of us reach for is a phone, and the second is a light switch that no longer works. An off-grid power kit is simply the gear that keeps the essentials running through a cut: a charged phone for calls and information, a torch to move around safely, and steady power for anything medical you depend on. Power cuts in the UK are usually short, but winter storms can knock out supply for a day or more, and rural areas often wait longest for repairs. A little preparation turns an anxious evening into a manageable one.

Start with capacity. A power bank is rated in mAh, but what matters is real charges: a 20,000mAh bank gives roughly three to four full phone charges once you allow for losses. Add lithium AA batteries, which hold their charge for years and cope with the cold far better than alkalines, to keep torches and radios going. Solar can top things up, but be realistic about British weather. A folding panel works well on a bright day, yet trickles slowly under heavy cloud, so treat it as a recharger rather than your only source.

Your car is a surprisingly capable backup. A jump starter doubles as a hefty power bank with USB outputs, and the vehicle's own battery can charge devices through a 12V socket. One firm rule, though: never idle an engine in a closed or attached garage. Petrol and diesel exhaust contains carbon monoxide, an invisible, odourless gas that kills, so only run an engine outdoors in the open air. Pair the kit with a carbon monoxide alarm, keep everything charged, and test it before the clocks go back.
