Trusted brands like Anker, Belkin, and Mophie consistently deliver dependable power banks. Even Energizer is now entering the market. With so many options, power banks are evolving to include features like Qi wireless charging, which is a great convenience if you forget a USB-C cable.
Choosing a power bank with sufficient capacity is crucial. A 20,000mAh battery can typically charge an iPhone twice or a tablet once. For laptops, opt for at least 45W output, with gaming laptops needing even more power to keep up.

These tuck neatly into side slots for tidy storage. Compact and lightweight at just half a pound, it’s the size of a smartphone.
This power bank is limited to its built-in cables, so some devices may require adapters. However, most modern devices, including recent iPhones, use USB-C, making it widely compatible.
With a 10,000mAh capacity, it’s ideal for charging smartphones and some tablets. It delivers up to 18W for a single device, charging an iPhone to 50% in about 30 minutes, though it’s not suited for laptops.

Key Features to Consider in a Power Bank
Capacity
Capacity, measured in milliamp-hours (mAh), is the most critical factor. Most flagship phones have around 3,000mAh batteries, so a power bank with at least 10,000mAh is ideal for multiple charges. Note that some power is lost during transfer, so actual capacity may be slightly less.
Ports and Charging Speeds
Charging capabilities vary widely. Look for Power Delivery (PD) support for maximum energy transfer. For phones, aim for at least 20W, ideally 30W, for fast charging. Tablets need at least 30W, and laptops require 45W to 60W to stay powered. Check port-specific speeds, as they can differ.
Also, consider the power bank’s recharge speed. A 20,000mAh battery with only 5W input takes hours to refill, so higher input wattage is a plus.
Power Bank FAQ
Should you drain your power bank before recharging?
No, draining lithium-based power banks, common in most models, isn’t necessary and may reduce capacity. Recharge before it’s fully depleted or every few months if unused.
Can you bring power banks on a plane?
Yes, lithium-ion or lithium-metal power banks are allowed in carry-on luggage only, per TSA rules, due to fire risks. They’re limited to 100Wh (about 27,000mAh), so standard 10,000mAh chargers are fine.
How long do power banks last?
Quality power banks from brands like Anker or Belkin typically last 2 to 4 years, depending on usage and care. Higher-capacity models often outlast lower-capacity ones. To extend lifespan, avoid overcharging, store in a cool, dry place, and recharge fully every three months.
