Best Fast-Charging: Anker 737 Power Bank (PowerCore 24K)

The Anker 737 Power Bank isn’t shy about power. Inside the metal shell sits a 24,000 mAh pack that pushes and accepts up to 140W through USB-C Power Delivery 3.1. That’s enough to bump a 16” MacBook Pro from dead to 50% in about half an hour or re-charge itself fully in about 52 minutes with a high-wattage brick.

Two USB-C ports plus a USB-A let you top off three devices at once, while a smart digital display tracks real-time battery percentage, port wattage, temperature, and more. At roughly 22 oz, it’s bag-friendly rather than pocket-sized, making it the go-to for fast top-ups on work trips or conference days.

At just 0.58” thin and 7 oz, it slides into skinny jeans yet still offers 30W wired charging and recharging via the USB-C port. The magnetic grip feels secure even while scrolling and texting, and the aluminum Qi2 coil paired with ActiveShield 2.0 keeps temps in check for more efficient wireless sessions.

The 10,000 mAh battery gives you roughly two phone charges, and it comes in four colors to match Apple’s current palette.

Best for: iPhone owners who want the full 15W snap-on wireless charging and fast wired charging, minus the brick-in-pocket feel.

Two USB-C ports (140W max single) and one USB-A mean you can juice a laptop, tablet, and phone simultaneously without throttling.

A Bluetooth-enabled app locates the bank under your couch, and a smart display shows real-time battery% and per port wattage. Despite the large capacity, it re-charges itself at up to 170W via dual USB-C inputs and hits 100% in under 40 minutes with a compatible wall charger.

How to Choose the Right Portable Charger for Your Needs

Picking the best portable cell phone charger is about matching your daily routine: how much power you need, how fast you need it, and how you’ll carry it. Let’s take a closer look:

Pick the Right Capacity (mAh and Wh)

Capacity affects both charging power and portability. For light use, like topping off your phone or earbuds, 5,000–10,000 mAh is more than enough. These models are slim, lightweight, and perfect for pockets or small bags.

For heavier users or frequent travelers, 15,000–20,000 mAh gives you 2-3 phone charges or a full tablet recharge without much extra bulk.

If you’re charging laptops or multiple devices throughout the day, look for 24,000 mAh or more. These high-capacity banks are heavier and bulkier but worth it for all-day power.

Just keep in mind that anything over 27,000 mAh (100Wh) are not allowed in carry-on luggage without airline approval.

Check the Wattage and Charging Standard

Look for portable chargers that support USB-C Power Delivery (PD), which is the go-to fast-charging standard now. Most phones only need about 20 to 30W, but if you’re charging a laptop, you’ll want something that can handle 60 to 100W or more. Check your device’s charging requirements and make sure the power bank can meet or slightly exceed them on a single port.

Don’t Overlook Input Speed

Fast output is great, but fast input matters, too. A 20,000 mAh+ power bank with slow recharge speed can take 6–8 hours to fill up. Look for USB-C input at 60W or higher if you want a full recharge in under two hours.

Port Selection Matters

USB-C is now the standard for fast charging, but having a mix of ports (USB-C and USB-A) makes your power bank more flexible. If you carry multiple devices, make sure your bank has enough ports and enough power to handle them all at once.

Want Wireless? Go Qi2 if You Can

Magnetic wireless chargers are super convenient: no cables, just snap and go. But if you care about speed, Qi2-certified power banks are the way to go. They offer full 15W wireless charging with better alignment and efficiency. Standard magnetic Qi chargers look similar but max out at 7.5W.

Look for Safety and Build Quality

A good power bank should include protection against overheating, short-circuiting, and overcharging. Certifications like UL, CE, or FCC are worth checking for. Also, consider build quality—rugged plastic or aluminum shells are more durable, and rounded edges or slim profiles make everyday carry a lot easier.

Conclusion

At the end of the day, the best portable charger is the one that fits your gear, your pace, and doesn’t make you dig for cables or wait hours for a full charge. Hopefully this roundup helped you zero in on the right pick. Whether you’re team MagSafe, carrying a laptop regularly, or just tired of watching your battery bar drop into the red, there’s something here that’ll keep you powered without the hassle.

FAQs

Are portable chargers allowed on airplanes?

Yes, portable chargers are allowed on airplanes, but they must be carried in your hand luggage, not in checked baggage. Most airlines permit power banks up to 100Wh without special approval, which covers most models under 27,000mAh.

Can I charge multiple devices simultaneously with a portable charger?

Yes, many modern power banks support multiple USB‑C and USB‑A ports to charge several devices at once. For instance, the Anker Prime 27,650 mAh (99.5 Wh) power bank features two USB-C ports and one USB-A port, delivering up to 250W total output, so you can charge a laptop (even a MacBook Pro), smartphone, and tablet at the same time from a single unit, without reducing speed.
