Factors to Look for When Choosing a Portable Phone Charger

Power banks come in all shapes and sizes, and the best portable phone battery charger depends on how you plan to use it. Here are the key things to consider before buying:

Capacity: Understanding mAh and Wh

Start by figuring out how much extra power you really need.

• A compact 5,000 mAhunit is fine for topping up your phone once during the day.
• At 10,000 mAh, you can usually get one or two full charges.
• Jump to 20,000 mAhand you’ll have enough to keep a phone, tablet, or even a handheld console going.
• Anything higher moves into laptop-grade power banks, ideal for heavy users.

When flying, airlines don’t regulate milliamp-hours (mAh) directly—they go by watt-hours (Wh). In Canada, CATSA follows International Air Transport Association (IATA) rules:

• Up to 100 Wh (≈27,000 mAh at 3.7V):allowed in carry-on with no restrictions.
• 101–160 Wh:generally permitted, but you’ll need airline approval and are usually limited to two units.
• Over 160 Wh:not allowed on passenger flights.

If your charger only lists mAh, use this formula to convert:

Wh = (mAh × V) ÷ 1000 (where V is typically 3.7V). For example, a 20,000 mAh pack equals about 74 Wh—well within the 100 Wh allowance.

Charging Speeds and Standards

A good portable charger should deliver more than a slow trickle. Look for power banks that feature USB-C ports with Power Delivery (PD), today’s universal fast-charging standard.

For phones, 20–30W is usually enough. Tablets and thin laptops usually do best with 45–60W. But if you’re powering a high-performance laptop on the go—or want to charge several devices at full speed at the same time—you’ll want a charger that supports up to 100W (PD 3.0) or even 140W (PD 3.1).

If you’re using a Samsung flagship, check for PPS (Programmable Power Supply), which enables faster and cooler charging. For example, Galaxy S24 Ultra and Z Fold models require PD 3.0 with PPS at 45W to hit full speed.

Wireless Charging Options

For convenience, many power banks now support wireless charging. MagSafe-compatible battery packs can magnetically attach to iPhones, and the new Qi2 standard boosts wireless speeds to 15W—double the older 7.5W limit. That makes wireless charging faster and more efficient than ever.

Recharging the Power Bank

Don’t forget: your charger itself needs charging. Models that accept 30W+ USB-C input can refill in under two hours with the right wall adapter. Lower-input models may take half a day to recharge, which is inconvenient if you depend on it daily.

Ports and Built-In Cables

USB-C is now the go-to standard. Look for power banks with multiple USB-C outputs, and treat USB-A as a backup for older devices. Some models come with integrated cables, which can be handy if you tend to forget cords when travelling.

Safety and Certification

Battery safety should never be overlooked. Power banks should comply with UN 38.3 testing to be carried on flights, which covers stress tests like vibration, shock, and overcharge. Look for models tested to UL 2056, which verify protections against overheating, fire risk, and mislabeled capacity. Other marks like CE, FCC, and RoHS are also reassuring signs of quality.

Size, Weight, and Durability

The more capacity, the heavier the bank. If portability is key, look for slim models under 250 g. For travel or backpack use, a bit more weight isn’t an issue, but durability matters. Reinforced corners and a tough exterior will better handle drops and scuffs.

Tips to Maintain Your Portable Phone Charger

Even the best portable mobile phone charger can fail early if not cared for properly. Follow these habits to keep yours working longer.

• Charge regularly:Keep it between 20%–80% when possible. Letting it hit 0% too often shortens battery life.
• Don’t overcharge:Once it’s full, unplug it. Constant overcharging can strain the battery.
• Avoid extreme heat or cold:Leaving a power bank in a hot car or freezing bag can shorten its lifespan. Room temperature is best.
• Use quality cables and adapters:Stick with certified cables and the recommended wattage to avoid stressing the battery.
• Store partially charged if unused:If you’re putting it away for a while, keep it around 50% charged to protect the cells.

Conclusion

Choosing the best portable phone charger in 2025 comes down to matching the right size and features with your lifestyle, whether that’s a slim snap-on battery pack for quick iPhone top-ups or a powerhouse that keeps your laptop running on the go. Anker’s latest lineup shows how far portable charging has come: faster speeds, smarter safety, and designs that actually fit into your day. With a little care, your charger will be a reliable companion for years, making sure you stay connected whenever and wherever you need it.

FAQs

What is the best portable phone charger to buy?

Which is better, a 10,000mAh or a 20,000mAh powerbank?

it depends on how you use it. A 10,000mAh power bank is lightweight and easy to carry. It usually provides around two full phone charges, making it ideal for daily use or short trips. A 20,000mAh power bank, on the other hand, is bulkier but can deliver four to five full charges. It’s a better fit if you travel frequently, carry multiple devices, or expect to be away from outlets for longer stretches.

What’s the best power bank for a phone?

For phones, a compact charger that balances size and speed usually works best. The Anker MagGo Power Bank (10K, Slim) is ideal if you want both wireless MagSafe charging and a strong 30 W USB-C port for wired fast charging. If you’re an Android user who needs higher wattage, the Anker Nano Power Bank (10K, 45W) with its built-in USB-C cable is a great option—it even supports Samsung Super Fast Charging up to 45 W. Both are reliable, portable, and built for daily phone use.

How many times can a 20,000mAh power bank charge a phone?

A 20,000mAh power bank can usually recharge a smartphone about 3 to 5 times, depending on your phone’s battery size. For example, if your phone has a 4,500mAh battery, you’ll get roughly 3 full charges, while smaller batteries around 3,000mAh might get 4 to 5. Keep in mind that energy is lost during charging due to heat and voltage conversion, so you won’t get the full 20,000mAh.
