| Primary job | Running or charging multiple small devices, plus some mains-powered kit within the station's wattage limit. | Charging phones, USB torches, small radios, tablets and other low-power USB devices. |
| Best UK use case | Longer winter power cuts, households with several devices to keep alive, car camping and off-grid work. | Short outages, commuting delays, grab bags, everyday carry and keeping one phone reachable. |
| What it cannot do | It still will not safely run high-draw heating or cooking appliances for long; check rated watts and surge watts before relying on it. | It cannot power normal plug-in appliances unless they charge over USB, and it usually has no mains socket. |
| Capacity and runtime | Much larger reserves, often measured in watt-hours, enough for repeated phone charges and several hours of low-draw equipment. | Usually 10,000 to 20,000mAh, enough for one to several phone charges depending on the handset and losses. |
| Weight and storage | Bulkier and heavier, better kept at home, in a vehicle or with camping kit rather than carried daily. | Pocketable or bag-friendly, easy to keep charged and move between home, work and travel. |
| Charging before a storm | Takes longer to refill from the mains; larger units should be checked and topped up before storm warnings. | Quick and simple to recharge overnight, so keeping two in rotation is realistic for most households. |
| Typical price band | Roughly 200 to 1,000 pounds depending on capacity, output and battery chemistry. | Roughly 15 to 50 pounds for most useful emergency-ready models. |
