Higher wattage means faster charging, while higher mAh means longer battery life between charges. Consider the devices you’ll be charging to ensure the power bank’s output matches your needs.
What’s the power capacity of a good power bank?
OMG, you NEED a power bank with at least 15W if it’s USB-C! Seriously, anything less and you’ll be waiting FOREVER. But honestly, 18W is the sweet spot for USB Power Delivery – that’s where the real speed is at! Think lightning-fast charging, like, seriously, fast.
Now, if you’re stuck with old-school USB-A or Micro-USB (so last season!), you’ll still need a minimum of 8W. Anything lower and you might as well charge it overnight. It’s gonna be slooooow.
Pro Tip: Check the mAh (milliampere-hour) rating too! Higher mAh means more juice for multiple charges. But wattage (W) is what determines charging speed – think of it as the highway your phone takes to get full. Higher wattage = faster highway!
Another Pro Tip: Look for power banks with multiple ports! Charging two devices simultaneously? You’ll need that extra port for all your gadgets.
And one more thing: Don’t forget about fast charging protocols like Quick Charge or Power Delivery. These are like turbo boosts for your charging speed, making sure you’re getting the full potential of your power bank’s wattage. Seriously, you don’t want to miss out on the latest tech.
How many watts should a good power bank have?
For smartphones, a power bank with 10W to 18W output is usually sufficient. Anything less and charging will be painfully slow; much more is generally overkill unless you have a particularly power-hungry phone. I’ve found that 18W is a sweet spot – fast enough without excessive heat.
Tablet users should aim for 18W to 30W. Many tablets consume significantly more power than smartphones, and a lower wattage power bank will result in very slow charging, or even prevent charging altogether if the power demand exceeds the supply. I personally use a 27W model and it works flawlessly with my iPad.
Laptop users require significantly more power. 30W to 100W, or even higher, is the range to consider. The specific wattage needed depends entirely on your laptop’s charging requirements; check your laptop’s specifications to determine the appropriate power delivery (PD) wattage. Don’t skimp here – underpowered charging leads to slow charge times, and in some cases, can even damage your laptop battery.
Important Considerations:
