How long should a power bank last in Australia?

A power bank bought for around $50 should last about 12 months or more.

A power bank that stops holding charge or swells within a year or two is a fault, however cheap it was.

That’s our guide, and plenty last longer.

The law doesn’t set a fixed number. Goods have to last as long as a reasonable person would expect, given what they are and what you paid. If it fails sooner through no fault of yours, the shop that sold it has to put it right, even when the maker’s warranty has run out.

Takes a minute. It works out where you stand and what to say.

Is mine still covered?

Our guide to how long a power bank should last, by price:

Price paid	Should last about
Up to $100	12 months
$100 to $500	2 years
Over $500	4 years

For one bought around $50:

Under 7 months: very likely covered.
7 months to 12 months: borderline, so worth asking.
Over 12 months: harder, but it isn’t a cut-off.

These are guides, not law.

Signs it’s a fault

It no longer charges, or holds only a fraction of its capacity
The case swells, overheats or smells
The ports stop delivering power

What usually isn’t covered

Damage from a drop, water or a hot car
Use outside the maker’s limits
A change of mind, misuse, or a fault you knew about when you bought it.

Safety first. If it overheats, sparks, smells of burning or has hurt someone, stop using it. Then check Product Safety Australia for a recall.

What to do

Find your proof of purchase. The receipt is best. A bank or card statement, an order email or a warranty registration also works.
Go back to the shop you bought it from. Not the maker. The shop is responsible, and it can’t send you to the manufacturer instead.
Say what’s wrong and what you want. For a minor problem, the shop can choose to repair it first. For a major one (it’s unsafe, or you wouldn’t have bought it if you’d known), you choose a refund or a replacement.
If they say no, go up a step. Ask again politely, in writing if you can, and keep copies. Then contact your state or territory consumer protection agency. If you need to, your state tribunal is the next step.

What to say at the counter

“I bought a power bank here on [date]. [What’s wrong.] It hasn’t lasted as long as I’d reasonably expect for what I paid, so it isn’t of acceptable quality under the Australian Consumer Law. I’d like it repaired, replaced or refunded.”

A tip for a power bank

If it swells or gets hot, stop using it and keep it away from anything flammable. Then take it back.

Common questions

How long should a power bank last?

By our guide, a power bank bought for around $50 should last about 12 months or more, and plenty last longer. The law doesn’t set a fixed number. Goods have to last as long as a reasonable person would expect, given what they are and what you paid.

Does the consumer guarantee still apply to a power bank after the warranty ends?

Yes. They’re separate from the maker’s warranty and from any extended warranty, and they don’t have an end date. What matters is whether it lasted as long as a reasonable person would expect for what it was and what it cost.

Who do I go to if a power bank fails, the shop or the maker?

The shop that sold it. The shop is responsible for putting it right under the consumer guarantees, and it can’t send you to the manufacturer instead.

Is it worth the bother if a power bank was cheap?

Yes. Cheap things are covered too, with no minimum price. A quick, polite ask at the service desk is usually the way to go. You’ll still need proof you bought it. A receipt, a bank or card statement or an order email will do.
