A charger and cable look like simple things, so people often buy the cheapest one they find. But these two items sit plugged into your wall for hours, often at night. A poor one can charge slowly, damage your battery or, in the worst case, become a safety risk. Here is how to choose well.
- Match the connector (USB-C, Lightning, micro-USB) before anything else.
- Check the watts: pick a charger that meets what your phone supports, and a cable that can carry it.
- Look for certification marks and clear branding, and avoid prices that look too good to be true.
- Stop using any charger that overheats or smells odd.
Step 1: Match the connector
Check which port your phone uses.
- USB-C: most recent Android phones and newer iPhones, laptops and tablets.
- Lightning: older iPhones.
- Micro-USB: older, budget Android phones and some accessories.
Also check the other end of the cable. Many cables are USB-A to USB-C, while newer chargers often have USB-C ports, which need a USB-C to USB-C cable.
Step 2: Check the power rating
Power is measured in watts (W). Your phone can only accept what its own charging circuit allows, so a bigger charger does not mean faster charging than your phone supports.
- Find your phone's maximum charging speed in its specifications.
- Choose a charger that meets or slightly exceeds it.
- Make sure the cable can carry that power too. A thin, low-quality cable can limit speed.
Step 3: Look for fast-charging details
Real fast charging names a standard, such as USB Power Delivery (PD), and states the watts. If a listing says "super fast charging" with no numbers or standard, be careful.
Step 4: Look for certification and clear branding
A proper charger or adapter shows the maker's name, model number, input and output ratings and the relevant certification marks printed on the body or box. In India, look for the BIS mark where it applies. If the label is missing, blurry or misspelled, do not buy it.
Step 5: Check the build
- Weight: a very light charger can mean missing safety components inside.
- Connectors: they should fit snugly without wobbling.
- Strain relief: the cable should be reinforced where it meets the plug, since this is where most cables break.
- Cable material: braided or thick, flexible coatings usually last longer.
Signs of a fake or poor-quality product
- The price is far below the normal market price for that brand.
- Spelling mistakes or blurry printing on the box and label.
- No model number, ratings or certification marks.
- The charger gets very hot, smells odd, or makes a buzzing sound.
- Charging keeps stopping and starting.
Safe charging habits
- Do not charge under a pillow or on a bed covered with blankets.
- Unplug damaged or frayed cables immediately.
- Avoid using your phone heavily while it fast-charges in a hot place.
- Use the original or a good-quality replacement charger.

Frequently asked questions
Can I use any cable with any charger?
Physically many fit, but the speed and safety depend on both being suitable. A cheap cable can limit fast charging.
Does a higher-watt charger damage my phone?
A good charger delivers only what your phone requests, so a higher rating alone is not a problem. Poor-quality chargers are the real risk.
Why does my phone charge slowly?
Common reasons are a weak cable, a low-power adapter, a dirty port or heavy use while charging. Try a different cable and charger to find the cause.
How often should I replace a charging cable?
Replace it when you see fraying, bent connectors or intermittent charging. There is no fixed time, as it depends on use and build quality.
Is it safe to charge my phone overnight?
With a good-quality charger in a well-ventilated place, many people do. Avoid cheap adapters and keep the phone off soft bedding.
