If you work from home, a winter power cut is not just a comfort problem — it can stop your income mid-morning. The laptop battery buys you an hour, but the router dies almost immediately, the desk goes dark early on a grey afternoon, and there is no kettle for the coffee that keeps a long day going. A small, dedicated kit kept by the desk means a two-hour outage becomes a minor interruption rather than a lost meeting or a missed deadline.
These picks are aimed squarely at keeping a home office running, not at a full household emergency. A compact power station has proper mains sockets to keep a laptop charger and — crucially — the broadband router alive; a large power bank and a fast USB-C bank handle the phone, hotspot and repeated laptop top-ups; a flameless rechargeable lantern lights the desk safely; a small rechargeable head torch frees both hands for the fuse box or cabling; and an insulated flask, filled before the power goes, keeps a hot drink going through the outage. If you rely on broadband for work, a small power station for the router is the single highest-value item here.
A portable battery pack keeps your phone, GPS, and headlamp charged when mains power is unavailable. Essential for maintaining communication, navigation, and emergency calling capability in the field.
For survival use, a minimum of 10,000mAh provides 2-3 full smartphone charges. A 20,000mAh unit covers a multi-day expedition comfortably. Balance capacity against weight — every 10,000mAh adds approximately 200 grams. For day hikes, 5,000mAh may suffice; for extended trips, go larger.
Look for at least two USB output ports so you can charge multiple devices simultaneously. USB-C Power Delivery (PD) or Quick Charge support significantly reduces charging time. Ensure the output is sufficient for your devices — phones typically need 5V/2A minimum for efficient charging.
Standard consumer power banks are fragile and water-sensitive. For outdoor and survival use, choose a ruggedised model with an IP65 or higher water-resistance rating, rubber bumper protection, and a dust-proof charging port cover. Some models include a built-in torch — a useful bonus.
Lithium-ion batteries lose capacity significantly in cold temperatures — up to 40% at freezing point. For UK winter use, keep your power bank inside your jacket close to your body. Some premium models use lithium polymer cells that perform better in cold conditions.
Always fully charge your power bank before any trip. A 20,000mAh power bank at 50% charge is effectively a 10,000mAh unit. Make charging your power bank part of your pre-trip preparation checklist, and keep your home emergency power bank on a maintenance charge cycle.
A power bank is useless without the correct charging cables for your devices. Carry a short USB-C and Lightning cable (or whichever your devices require). Keep dedicated cables stored with the power bank so they are never forgotten. Consider a multi-tip cable to cover all eventualities.
In a survival situation, ration your power bank capacity for genuine needs: emergency calls, navigation, and essential lighting. Avoid using it to scroll social media, take photographs, or play music. Put your phone in aeroplane mode when not actively using mobile data to dramatically extend both phone and power bank life.
A compact 256Wh LiFePO4 power station with a 300W pure sine wave socket and 100W USB-C. Light enough to carry one-handed, big enough to keep phones, a router and lights running through an outage, and it recharges fully in about an hour.
A high-capacity 20,000mAh pack that keeps several devices going across a long outage. The choice when you need days of backup power, not hours.
A high-output 20,000mAh bank with a built-in retractable USB-C cable and enough power (165W across its ports) to fast-charge a laptop as well as phones and tablets. Handy in a power cut when you need to keep several devices alive, or on the move when you don't want to carry loose cables. It's heavier than a pocket bank, so think of it as the household or grab-bag backup rather than everyday carry.
A rechargeable LED lantern that throws a wide, even light rather than the narrow beam of a torch, which makes it the better tool for lighting a room or a tent during a power cut. It runs off its own built-in battery and recharges over USB, with brightness and runtime settings so you can trade light output for a longer burn. A sensible backup to keep charged on a shelf alongside your torches.
A compact 400-lumen rechargeable head torch that also clips off as a cap light. Hands-free light for reading a meter, fixing something in the dark, or moving around the house safely when the power's out.
A rugged stainless steel vacuum flask that keeps drinks hot for up to 24 hours and cold for 24 hours. The 1.2L size suits a household through a power cut, with a leak-proof stopper and an insulated cup lid for sharing a hot brew.
