How to Choose the Best Power Bank for Your Needs

So, what is the best power bank charger? It should give you enough reserve power for the devices you carry, without adding unnecessary weight or taking too long to recharge.

Capacity matters, but so do output, charging standards, input speed, ports and safety. Focus on the factors below rather than simply choosing the model with the biggest battery or highest wattage.

1. Balance Capacity with Portability

Choose capacity around how long you normally spend away from a socket and how much weight you are willing to carry.

• 5,000mAh: Best for emergency phone top-ups and lightweight everyday carry. Expect roughly one phone top-up.
• 10,000mAh: A practical balance for most phone users, commonly giving around 1–2 full smartphone charges.
• 20,000–25,000mAh: Better for long journeys, several devices or roughly 3–5 phone charges, depending on the phone and conversion losses.
• 25,000mAh+: More useful for laptops and demanding multi-device setups.

Weight can range from around 100–250g for compact phone-focused models to roughly 500–600g for high-capacity laptop power banks, so consider whether it needs to fit in a pocket or will normally stay in a backpack.

If you fly regularly, also check the Watt-hour rating. Under current UK Civil Aviation Authority guidance, lithium-ion power banks up to 100Wh (roughly 27,000mAh at a nominal 3.7V) can normally be carried in cabin baggage without airline approval, while 100–160Wh requires approval.

2. Match Output and Fast-Charging Standards to Your Devices

Start with the fastest-charging device you plan to connect.

• 20–30W: Suitable for fast charging many current smartphones.
• 30–65W: Useful for tablets and lighter USB-C laptops.
• 65–100W+: Better suited to larger laptops and faster laptop charging.
• 140W: Worth considering for compatible high-performance laptops that support higher USB-C Power Delivery levels.

For current USB-C devices, look for USB Power Delivery (USB PD). It allows the power source and connected device to negotiate an appropriate voltage and current rather than delivering one fixed level.

PPS, or Programmable Power Supply, is particularly useful for compatible smartphones because it can adjust voltage and current more precisely during charging. Samsung Galaxy devices are a common example where PPS support can matter for reaching their fastest supported wired charging speeds.

If you regularly charge several devices together, check the total multi-port output as well as the headline single-port wattage.

3. Check the Input and Power Bank Recharge Speed

Output tells you how quickly a power bank can charge your devices; input tells you how quickly the power bank itself can be refilled.

As a useful guide:

• 18–30W input: Fine for smaller 5,000–10,000mAh models.
• 45–65W input: More practical for larger everyday power banks.
• 65–100W+ input: Worth looking for on 20,000–25,000mAh models if quick turnaround matters.

Some high-capacity models also support dual-port input for substantially faster recharging.

Do not assume a power bank with 100W output also accepts 100W input. The two figures can be very different, so check both specifications separately.

4. Choose the Right Ports and Charging Options

For most new devices, prioritise USB-C, particularly if the same power bank needs to handle a phone, tablet and laptop. USB-A remains useful for older cables and accessories.

Consider what would genuinely simplify your setup:

• Multiple USB-C ports: Useful for laptop-and-phone charging.
• Built-in cables: Reduce the number of accessories you need to pack.
• Foldable or retractable connectors: Handy for quick phone top-ups.
• Qi2 magnetic wireless charging: Convenient for compatible phones when cable-free charging matters more than maximum efficiency.
• Dedicated wearable charging: Useful if it can replace a separate smartwatch charger.

5. Check Safety Features and UK Compliance

Look beyond generic claims such as “safe charging”. A well-designed power bank should include protections against overheating, overcurrent, overvoltage, overcharging and short circuits, ideally managed through a battery management system with active temperature monitoring.

For products sold in Great Britain, appropriate CE or UKCA conformity marking and clear manufacturer information are also worth checking.

For air travel, power banks should also comply with applicable lithium-battery transport requirements such as UN 38.3 testing.

6. Look for Smart Features You Will Actually Use

Extra features are worthwhile when they make everyday charging easier.

A built-in display can show battery percentage, live input/output wattage and estimated charging time, which is particularly useful on large multi-port models. App controls may be useful for monitoring power distribution or battery status on more advanced models, but they are rarely essential for a simple phone power bank.

Final Verdict

Finding the best power bank comes down to matching capacity and output to the devices you actually carry. A compact 5,000mAh model can be enough for everyday phone top-ups, while 10,000mAh offers more flexibility and 20,000mAh-plus models make more sense for laptops, several devices or longer trips.

At Anker, we offer options across each of these use cases, so compare our power banks to find the right fit for your routine.

Is 10000mAh enough for a power bank?

Yes. 10,000mAh is enough for most everyday phone users, typically providing around 1–2 full smartphone charges once normal conversion losses are taken into account. It is a practical size for commuting, full days out and short trips without the extra weight of a 20,000mAh-plus model. Choose a larger capacity if you regularly charge several devices, spend multiple days away from a socket or need meaningful laptop backup.

Can you take a power bank on a plane?

Yes, but power banks must be carried in cabin baggage, not checked luggage. Current UK CAA rules allow up to two power banks per person. Lithium-ion models up to 100Wh are allowed without airline approval, while those over 100Wh and up to 160Wh require approval. Power banks must also be protected against short circuits and must not be recharged on board. Check the UK CAA power bank guidance before flying.
