For phone charging during a household power cut, start with a charged power bank that fits your phone and cable, and choose its capacity around the devices you need to keep usable. Add a battery or wind-up radio if you need updates when internet access or mobile signal is disrupted; a separate torch and compatible spare batteries give those devices their own power arrangements. The UK Government Prepare campaign includes a portable phone power bank, radio and spare batteries in its preparedness guidance.
If calls and messages are the immediate concern, compare a power bank’s capacity and output with the phones and cables you intend to use. Electrical Safety First distinguishes the number of possible recharges from charging speed.
If broadband or mobile signal is disrupted, a battery or wind-up radio offers another way to receive broadcasts. The UK Government Prepare campaign recommends keeping a radio and spare batteries at home for power cuts.
If equipment may sit unused for months, make its charging and inspection routine manageable. Follow the power bank’s own storage instructions and keep batteries matched to the radio or torch that will use them.
For a household power-cut kit, settle the phone-charging need first, then decide how you would receive updates and use a torch without drawing on the phone battery. Keep the equipment charged and check that its cables, chargers and replacement batteries fit.
| Concern | What to check | Who this matters to |
|---|---|---|
| Phone power | Compare stated capacity with the devices you need to charge; check the output connection and your phone cable. | If keeping an essential phone usable is my priority, I need stored power that can actually reach it. Around 36% of consumers put phone continuity first. |
| Offline updates | Check the radio’s power method, locally useful reception and the exact spare battery type, if needed. | When a charged phone might still lack a network connection, I want another way to hear updates; around 29% of consumers prioritise offline information. |
| Stored-kit readiness | Read the exact model’s storage instructions and plan how you will inspect and recharge it. | If my kit will spend long periods in a cupboard, I need to be able to keep it ready. Readiness is the primary concern for around 21% of consumers. |
| Recharging and fit | Check the bank’s charging input and whether your charger, cable and phone connections are compatible. | Between interruptions, I need to replenish the bank using the equipment I have. Around 14% of consumers put that charging fit first. |
A larger mAh figure concerns stored capacity, not how quickly a phone charges. Electrical Safety First identifies output power as a separate factor.
Check the bank’s output connection and rating against the phone and cable, as well as the capacity you need.
The UK Government Prepare campaign warns that a power cut can interrupt internet access and possibly mobile signal. A charged phone cannot restore either connection.
Keep a battery or wind-up radio with the kit, along with compatible spare batteries where required and written details of useful stations.
Equipment left unused still needs care if it is to be ready for an outage. Anker’s guidance for its own power banks recommends periodic recharging during long-term storage; the appropriate routine depends on the model.
Follow your bank’s instructions, inspect it and its cable, and recharge it safely as part of a recurring kit check.
Government guidance says batteries and electrical products should carry the crossed-out wheelie-bin symbol and should not go in household rubbish.
Take an unwanted power bank to an appropriate battery or electrical-product collection point.
A reference point for comparing USB power-bank capacities and charging arrangements.
A reference point for a dedicated radio when broadcast updates matter separately from phone charging.
A reference point when considering a power bank alongside batteries for other kit devices.
These portable power banks address the phone-charging part of a household power-cut kit. Choose by your phone’s charging connection and the stated capacity; arrange a radio, torch or spare batteries separately if your kit needs them.

Consider this for charging a phone from stored power during an outage. The named capacity is 20000mAh, and it has an integrated cable; check that cable against your phone and confirm how you will recharge the bank.

This is an option if a built-in USB-C cable fits the phone you intend to keep charged. Its named specifications are 10,000mAh and 22.5W; check phone compatibility and the charger and cable you will use to refill the bank.

Consider this if an integrated cable suits the phone-charging arrangement in your kit. The name specifies 10000mAh and 33W; confirm the cable connection, your phone’s charging requirements and the model’s storage instructions.

This magnetic wireless option is relevant only if the intended phone and case suit that charging method. Its named specifications are 5,000mAh and 15W; check the stated MagSafe-compatible case requirement of under 2.5mm for the intended results, and confirm how the bank itself is recharged.
Start with a power bank whose connection works with your phone, then consider how many devices you need to charge before the bank can be refilled. Electrical Safety First explains that capacity affects possible recharges, while output power affects charging speed. A radio and torch serve different needs rather than replacing the power bank.
Follow the instructions for the exact model and check its charge periodically. Electrical Safety First advises keeping power banks away from heat and liquids and charging them uncovered in a ventilated place, not overnight or while out. Anker’s recommendation of about 60% charge and recharging every three months applies to its own long-term storage guidance, not to every power bank.
Yes, if you want a way to receive broadcasts when internet access or mobile signal is affected. The UK Government Prepare campaign recommends a battery or wind-up radio and spare batteries for power cuts; check reception and keep useful station details with the kit.
Take it to an appropriate battery or electrical-product collection point rather than putting it in household rubbish. UK government consumer guidance says batteries and electrical products should display the crossed-out wheelie-bin symbol to indicate that they should not be discarded with household waste.
