By Cygnett,

So, you’ve just upgraded your phone. You open the box to your shiny new toy, grab out your cable, but this time there’s no wall plug. A quick search online gets your head spinning…how are you meant to know which charge is best for you when there are so many options?
Take a deep breath, we’re here to help.

Break it down now

Where this gets tricky is that different phones accept different maximum charging powers.

Check out our charging guide for an easy breakdown.

Your phone knows what it’s doing so you don’t have to

Worried about your phone taking on more power than it needs? No need! Your phone controls how much charging power it receives and won’t be overcome by electricity flowing from a wall charger or power bank. Let’s look at iPhone 13 as an example.
