Top Power Banks to Buy in 2025

As someone who frequently travels across the country with a bag packed full of tech, I've faced the challenge of devices running out of power far from an outlet. Thankfully, modern power banks are both efficient and portable, making it a non-issue as long as I remember to charge them before departure. This ensures I'm never stranded with a dead phone.

A quick search on Amazon reveals a vast array of power banks from lesser-known brands. While these devices are essentially large batteries, opting for an inferior product can lead to serious issues such as overheating and swelling. Reliable brands like Anker, Belkin, and Mophie have established themselves as leaders in the market, and even Energizer is now making strides. Many of these power banks now support Qi wireless charging, adding convenience for those who might forget a USB-C cable.

The key is to choose a power bank with sufficient capacity to keep your devices running. A 20,000mAh battery pack can typically provide two full charges for an iPhone and one for a tablet. For laptops, especially gaming ones, a power bank with at least 45W of output is essential.

Having used countless power banks, I know what to look for and aim to help you find the perfect portable charger for your next trip.

The Belkin Boost Charge Plus 10K features integrated five-inch Lightning and USB-C cables for convenience. Worried about tangled wires? Belkin offers a solution with each cable neatly tucked into a slot on either side of the charger, ensuring organized storage when not in use. Despite the cables, the power bank remains compact, similar in size to a smartphone and weighing just half a pound.

While this power bank is limited to its built-in cables, it supports most electronics, including the latest iPhones, which use USB-C charging, making it versatile for most users.

With a 10,000mAh capacity, this power pack has ample energy to charge smartphones and even some tablets. It offers a maximum output of 18W when charging one device on either cable, making it less suitable for laptops. However, iPhones can reach 50% charge in under 30 minutes. It supports simultaneous charging of two devices at a total output of 23W and includes pass-through charging, allowing you to recharge the power bank via the USB-C port while charging another device.

2. Anker 737 Laptop Charger

Best Power Bank for Charging Laptops

### Anker 737

2This powerful charger ensures your laptop stays powered throughout the day. See it at AmazonProduct SpecificationsCapacity24,000mAhTotal output140WPorts1 x USB-C, 1 x USB-ASize6.13" x 2.15" x 1.95"Weight1.39lbPROSHigh wattage for fast chargingInformational displayCONSSize and weightLaptops demand more power than phones or tablets, necessitating robust charging solutions like the Anker 737. This charger provides a total output of 140W, suitable for most laptops and even some gaming models. Its 24,000mAh capacity can fully charge most laptops once or twice.

The downside is its size; the Anker 737 is 6.13 inches tall and 1.95 inches thick, larger than many laptops it's designed to charge. Weighing 1.39lbs, it adds significant weight to an already heavy bag.

However, its bulkiness is a small price to pay for the convenience of not running out of battery during critical work sessions, especially at events like CES where power outlets are scarce.

3. Charmast Portable Charger

Best Budget Power Bank

Its 20W output supports fast charging, though it's slower compared to premium models.

The design resembles the Belkin Boost Charge Plus 10K but is thicker at about one inch and heavier at 0.8lbs. While it may take an hour and a half to charge your phone instead of one, the trade-off for a more affordable price is worthwhile.

Most use the first-generation Qi standard, limited to 7.5W output. The Anker MagGo, however, supports Qi2, providing up to 15W, close to the 20W fast charging standard.

At just 0.44lbs and 0.58 inches thick, the MagGo is highly portable. Its 10,000mAh capacity offers one or two full charges for an iPhone, and its USB-C port doubles the charging speed.

What to Look for in a Power Bank

Capacity

The capacity of a power bank, measured in milliamp-hours (mAh), is crucial. Most flagship phones have a 3,000mAh battery, so a power bank with at least this capacity can double your phone's life. Standard power banks today offer 10,000mAh or more, providing multiple charges on the go. Remember, some energy is lost in transfer, so you won't get the full capacity.

Ports and Charging Speeds

Chargers vary in their output capabilities, with some supporting standards like Power Delivery (PD) for maximum energy transfer. For quick phone charging, at least 20W is recommended, though 30W is better for larger batteries. Tablets require at least 30W, and laptops need 45W to 60W. Consider the charger's input speed as well; a 20,000mAh battery with a 5W input will take longer to recharge.

Power Bank FAQ

Should you drain your power bank before charging it again?

No, draining lithium-based batteries fully can damage them. Charge your power bank before it's completely depleted or every few months if not in use.

Can you bring portable power banks on a plane?

Yes, you can bring power banks with lithium-ion or lithium-metal batteries in your carry-on luggage, but not in checked bags due to fire risk. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh charger is fine.

How long do power banks last?

Power banks from reputable brands like Anker and Belkin typically last 2 to 4 years. Lifespan depends on usage, build quality, and capacity. To extend life, avoid overcharging, store in a cool, dry place, and charge fully every three months.
