Wall Chargers: What Wattage Really Means (And Why It Matters)

Whether you’re powering a phone, tablet, or laptop, the right wall charger makes all the difference. It’s not just about speed—it’s about compatibility, safety, and having a charger that works across all your devices without slowing you down.

What to look for in a good wall charger.

•    USB-C Power Delivery (PD): This is the current fast-charging standard. It adapts the output depending on the device—so it won’t overpower your device but will still fast-charge your phone, tablet or laptop. 
•    Multiple ports: Handy if you’re charging more than one device at a time—think phone + smartwatch, or tablet + earbuds.
•    Compact, travel-ready size: Ideal for on-the-go setups without adding bulk to your bag.
•    Smart charging protection: Keeps your devices safe from overheating or overcharging.

Not all wall chargers are created equal. The power output—measured in watts (W)—makes a big difference in how quickly your device charges, and whether it can handle things like tablets, laptops, or multiple devices at once.

So, what’s the deal with watts?

Wattage is simply a measure of how much power your charger can deliver. A higher wattage = faster charging, but only if your device supports it. If your phone maxes out at 25W, using a 65W charger won’t damage it—it’ll just charge at its fastest supported speed. The benefit? That same charger can also handle your laptop, earbuds or tablet without needing separate gear.

Charging your phone with a basic 5W plug (like the ones we all used to get in the box) takes over 2 hours. With a 25w or more powerful charger, that drops down to under an hour for most newer models. It’s the difference between leaving home with a half-full battery and being good to go after a quick top-up while you get ready.

Which Wall Charger Is Right for You?

✅ Quick Tip:
Don’t judge a charger by size alone. GaN tech (used in most of our wall chargers) runs cooler and faster in smaller bodies, while eco chargers give you solid performance without the environmental baggage.

Power Banks: Pick the Right Power for Your Day (or Week)

Power banks aren’t just for emergencies—they’re part of the everyday kit now. Whether you’re off-grid, on a job site, or just smashing through back-to-back meetings, the right power bank means you’re never scrambling for a charger.
But not all are built equal. Some are good for a quick top-up. Others? Full workstations in your backpack.

What to look for in a good power bank:

But here’s where most people get it wrong: it’s not just about size. If you want fast, reliable charging, look for:
•    USB-C with Power Delivery (PD): adapts to each device for safe, efficient charging
•    Output wattage: phones can charge on 18–30W. Laptops need at least 45W, ideally 60W+
•    Multiple ports: top up your phone and your earbuds at the same time
•    Build and portability: slim, rugged units are easier to carry and last longer

Power at a Glance: What You Need & Why It Matters

When buying a Powerbank, there are 2 important things to look at:

1.    W or Watts, how fast it charges and what it can charge

2. mAh. When you see mAh, think of it like fuel capacity. More mAh = more charges.

✅ Quick tip:
Look at both numbers:
•    mAh = how much charging power it can hold
•    W = how fast it charges and what it can charge

Ready to find the ideal Power bank for your situation?

Just take a look at the table below for your Powerbank match.

✅ Quick tip:
For phone users, any 18–30W power bank will charge fast.
For laptops, look for 60W+ USB-C PD, and mAh over 20,000 so it lasts longer.

Cables That Actually Keep Up

Not all cables are created equal. Some are built to charge. Others are built to charge fast and move data. And a few, like the ones from EFM, are built to last through real life, not just sit pretty in a box.
If you’ve ever had a cable split at the connector, tangle itself into a knot, or crawl at snail-speed while transferring files, you’ll know why quality matters.

 What Makes a Great Cable?

• Power only vs Power + Data: Some cables just charge. Others can move files, videos, and backups. Always check the label.
• Transfer Speed: For moving files, video or syncing devices, look for 480Mbps (standard) or 5Gbps+ (USB 3)
• Charging Wattage: Make sure to check how much power your device needs.  Laptops need a minimum of 100W.
• Cable Length: Short (1m) for desk or car setups. Longer (2m+) for flexibility around the house.
• Braided & Reinforced: Helps prevent wear and tear, twisting, and fraying at the ends. Key for daily use.
  

    ·     Connector types: Lightning cables are used for iPhone 14 and older. Most phones charged through USB-C

✅ Quick Tip:

Need to charge your phone fast? Make sure your cable supports Power Delivery (PD) and matches your charger’s wattage. Using a high-wattage charger with a basic cable = slower speeds. Match both for max performance.
