What a used power bank is worth by condition
Condition does more to the price than anything else. These figures are worked from the top of the range for power banks, so treat them as a starting point and adjust for the specifics of yours.
| Condition | Typical price | What it means |
|---|---|---|
| New with Tags | £35 | Unused, tags or seals intact |
| Like New | £29 | Barely used, no visible wear |
| Good | £22 | Light signs of use, complete and working |
| Fair | £15 | Heavily used, or a described fault or missing part |
| For Parts | £8 | Not working or incomplete, sold as seen |
These are the five grades WishThrift listings use, and sellers set the grade themselves — see what each condition grade means. Figures are shown in pounds as a reference point. On WishThrift prices display in your own currency, and sellers set their own asking price.
What raises the value of a power bank
- Recent purchase with capacity still close to rated
- Higher capacity and fast-charging support
- Recognised brands with safety certification
- Original cables included
What lowers it
- Swollen cells, which are a fire risk
- Capacity well below the rated figure
- Unbranded banks with inflated capacity claims
- Failed charging ports
How to work out what yours is worth
- Charge fully and test how many phone charges it delivers
- Inspect the casing for any bulging
- Note the rated capacity and the real-world result
Once you have those three answers you can place your own power bank on the table above with reasonable confidence. If it sits between two rows, price it toward the lower one — items priced honestly sell faster than items priced hopefully.

Frequently asked questions
Are used power banks worth selling?
Recent, recognised-brand ones sell for small sums. Older banks have degraded and are worth little.
Is a swollen power bank dangerous?
Yes. A bulging casing means a failing lithium cell, which is a fire risk. It should be safely disposed of, not sold.
Do capacity claims matter?
Unbranded banks often overstate capacity considerably. Test it in practice and quote the real figure.
