What type of charger does my phone need?
Check your phone’s charging port. Most current Android phones and iPhone 15 or later use USB-C, so a USB-C charger supporting USB Power Delivery (PD) will charge them quickly. Older iPhones use a Lightning cable. A higher-wattage PD charger is safe because the phone only draws the power it supports.
Typical charging power
| Device | Common fast-charge range | Suggested charger |
|---|---|---|
| Recent iPhone | About 20 W to 30 W | 20 W or higher USB-C PD |
| Samsung Galaxy | 25 W or 45 W (PPS) | 25 W or 45 W USB-C PD with PPS |
| Other Android | 18 W upward; some brands use their own systems | USB-C PD, or the brand charger for maximum speed |
| Earbuds and smartwatches | Low power | Any safe USB charger |
Figures are typical and vary by model; check your phone manufacturer’s guidance.
Multi-port chargers
Chargers with several ports share their total wattage between devices. A 65 W charger might give 45 W to one port and 20 W to another when both are used.
Safety
Buy chargers with a UKCA or CE marking from reputable sellers. Avoid very cheap unbranded chargers, damaged cables, and charging under pillows or on soft furnishings.
Frequently asked questions
Can I use my laptop charger for my phone?
If it is a USB-C PD charger, generally yes. The phone negotiates a safe power level.
Does fast charging damage the battery?
Phones manage fast charging to protect the battery, typically slowing charging as the battery fills. Heat is the main cause of battery wear.
