As of 13 August 2026, AI can choose a power bank.
Most people should do this themselves; the prompt is on this page.

If this goes wrong, you buy a power bank that is heavier, slower or less compatible than expected and can return or replace it.
What to actually do
Do it yourself
The route this page recommends
A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open the specification pages for each device you want to charge and record its model, charging connector and required charging standard or wattage.
- Decide how many charges you need between sockets, the maximum weight you will carry, your budget in pounds and whether you need one port or several.
- Find current UK manufacturer or retailer pages for power banks you are considering and paste their links or full specifications into the prompt.
- Paste the completed prompt into ChatGPT, Claude or Gemini and ask it to compare only the supplied products and facts.
- Open each recommended product's manufacturer page and compare its capacity, weight, ports, output wattage, charging standards and dimensions with the drafted comparison.
- Remove any product with an unverified or incompatible specification, then buy the remaining model from a retailer with a suitable UK returns policy.
- If you plan to fly, check the airline's current power-bank and battery rules separately before packing it.
Prompt
Help me choose a power bank for the UK market. My devices are: [device models]. Their charging connectors are: [USB-C, Lightning, Micro-USB or other]. I need to charge them [number of times or use case] before I can reach a socket. My preferred maximum weight and size are: [details]. My budget is: [amount in pounds]. I will use it [at home, commuting, travelling, outdoors or other]. I need these features: [for example, USB-C input, USB-C output, fast charging, several ports or pass-through charging]. First, explain which capacity, output wattage, ports and charging standards matter for my devices. Then give me a shortlist of suitable models that are currently available, using only specifications and prices I provide or that appear in the product links below. Do not invent or assume a specification, price, stock status or airline rule. For each model, state capacity, weight, dimensions, input and output ports, maximum output, charging-standard compatibility, likely limitations and who it suits. Flag any missing or conflicting information. End with one recommendation and the reason it fits my stated needs. Product links or specifications: [ paste links or manufacturer and retailer specifications here ] Treat airline and travel restrictions as a separate check. Tell me to confirm the current rule with the airline before travelling rather than presenting an uncertain rule as fact.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong
- AI cannot reliably know whether a product listing is current, accurate or still in stock.
- AI cannot test the real charging speed, heat, build quality or battery lifespan of a power bank.
- AI cannot infer your preferred compromise between weight, capacity, price and charging speed unless you state it.
- AI cannot guarantee that a product meets the current rules of your airline or travel provider.
- AI cannot take responsibility for damage caused by a counterfeit, faulty or misused battery.
Even on a YES, the friction has a name: real time truth and judgement under ambiguity.
How we scored this

FAQ
- Can AI tell me which power bank to buy?
- Yes, if you give it your device models, charging needs, budget and product specifications. Check its shortlist against the manufacturer's current page because listings and specifications can change.
- What information do I need to choose a power bank?
- Gather the devices you need to charge, their connectors, required charging speeds, how long you need to stay away from a socket and the weight you are willing to carry. Also decide your budget and whether you need features such as several ports or USB-C output.
- Can AI check whether a power bank meets airline rules?
- It can help you identify the battery information you need to check, but it cannot guarantee that the current airline rule has been applied correctly. Confirm the rule directly with your airline before travelling.
- Is it safe to use AI to choose a power bank?
- It is generally suitable for comparing ordinary consumer products when you verify the specifications yourself. Do not rely on an unverified recommendation for a damaged, swollen or unusually hot battery, and replace rather than use a battery showing those signs.
