Most people replace their phone every two years and blame the battery.

A lot of the time it's the brick.

Cheap chargers don't deliver the wattage on the box. They heat up, throttle, and trickle. Your phone spends more time at 20–80% than it should, so it feels "dead" by 4pm.

Three checks before you buy another charger:

1. Actual watts, not "fast charge"

Look for a real number: 30W, 45W, 65W. If it just says fast, assume 10W.

2. One cable that matches

USB-C to USB-C. If you're still using a USB-A brick with a dongle, you're leaving speed on the table.

3. GaN if you travel

Same power, half the size. Fold-flat plug. That's the whole upgrade.

I built SparkVolt because I was tired of replacing $12 cables every three months. The Essentials Kit is the stack I actually use: 30W charger, braided cable, 10,000mAh bank.

If you only buy one thing, buy the charger. Everything else is optional.
