Portable Charger Buyer's Guide 2025
Ever been caught with a dead phone when you really needed it? Whether you're heading to work, spending a weekend away, or dealing with a long day of meetings, a reliable portable charger can make all the difference.
This guide highlights what to keep in mind when choosing the right model in 2025. From compact options for daily use to high-output chargers that power laptops, there's something here for everyone.
What to Look for in a Portable Charger
Not every portable charger is built for every device. Some are made to pair with Apple's MagSafe, while others support both Android and iOS. Make sure your charger matches the phone you use.
Tip: MagSafe or Qi-certified models are best for iPhone users who prefer wireless charging.
Battery Capacity
A portable charger's capacity, shown in mAh, tells you how much power it can store.
-
5,000mAh: Small and easy to carry. Delivers one full phone charge.
-
10,000 - 20,000mAh: More versatile—ideal for people using multiple devices.
-
Over 24,000mAh: Great for laptops or for those who need power that lasts for days.
Tip: Match the capacity to your routine. One device? Go smaller. Laptop plus phone? Choose bigger.
Portability
Big power usually means more weight. If you're out for the day, a slimmer design is easier to carry. For trips or outdoor activities, the extra capacity of a larger charger can be worth it.
Tip: A portable charger with wireless charging also saves space by skipping cables.
Charging Speed
Two things matter here: how fast the portable charger recharges itself, and how quickly it charges your device.
-
Input Speed: Affects how long it takes to refill the charger.
-
Output Speed: Controls how fast it powers your phone or laptop.
Tip: USB-C PD or Quick Charge support means less waiting. Look for 20W or higher for phones and 65W or higher for laptops.
Best Overall: Anker 737 Power Bank (24,000mAh 3-Port Laptop Portable Charger)
If you carry multiple devices and need a high-capacity charger, Anker 737 Power Bank is a solid choice. Its 24,000mAh battery, two USB-C ports, and one USB-A port let you charge everything from a smartphone to a laptop.
Why It Stands Out:
- 140W output handles MacBooks and high-power tablets.
- A smart screen shows battery life, input or output levels, and more.
- Works with both USB-C and USB-A gear.
- Advanced safety features keep your charging setup protected.
Best Wireless: Anker MagGo Power Bank (10,000mAh Magnetic Battery with Qi2 Fast Charging)
Hate juggling cables? Anker MagGo Power Bank attaches directly to MagSafe-compatible iPhones and delivers 15W of Qi2-certified wireless power.
Why It Stands Out:
- 10,000mAh powers your phone up to 2 times.
- Qi2 support means fast, reliable wireless charging.
- The thin design fits easily in a pocket or bag.
- Allows charging of your phone even while the power bank is plugged in.
If you're looking for a portable charger with wireless charging that feels effortless, this one checks all the boxes.
Conclusion
In 2025, choosing the right portable charger comes down to your habits. Need speed and multiple ports? Anker 737 Power Bank has the power and flexibility. Prefer convenience and a clean design? Anker MagGo Power Bank offers wireless ease in a slim profile.
Whatever your priority, a good portable charger will help you stay connected no matter where you are.
FAQ
Are portable chargers and power banks the same?
Yes, most people use both terms to describe battery packs that charge your devices on the go. "Power bank" sometimes refers to larger-capacity models, while "portable charger" is often used for smaller, more compact ones.
What features make a good portable charger?
It depends on how many devices you need to charge and how quickly. A 10,000mAh charger is great for phones. Want to power tablets or laptops? Go bigger. Fast charging support, USB-C ports, and smart safety features are all worth having.
Will a 5,000mAh charger last through the day?
For many phones, yes. You'll usually get one full charge. It's perfect for emergencies or for tossing into a bag on days when you'll be out for a while. They also recharge quickly and are easy to carry.
