Buying Guide: Portable Power Banks


Which portable power bank is best to buy?

The best portable power bank depends on the types of devices that you wish to charge and keep powered throughout the day. No matter which device you plan to charge, though, your ideal portable power bank will have fast, streamlined power, and high-efficiency and versatile charging, all packed into an ultra-durable and compact design.

Portable chargers that have 2 or more charging ports and a minimum power output of 5,000mAh are a good starting point. Those with long lifespans and high battery capacities provide the most value, as they can recharge almost any smartphone, tablet, or other device multiple times over. They’ll last a long time and let you power your devices for years on end, eliminating the fear of your power bank suddenly running out of juice.

Power banks with lightweight, durable designs, are among the best ones to buy, especially ones that’ll easily fit in your backpack, gym bag, or pocket. These will provide greater peace of mind while you’re heading to work, school, or the gym, or if you’re on a long plane ride.

The Pocket Juice 10K Hyper Charge is currently an extremely popular power bank on Best Buy, with an overall 4.6 customer satisfaction rating, from nearly 100 reviews and counting. It is a great option for anyone wanting to power their devices on the go, thanks to its 10,000mAh battery capacity, reliable 18W power delivery, and streamlined charging for most USB-C and micro-USB compatible devices!

Are portable power banks worth it?

Portable power banks are absolutely a wise investment, especially if you like to travel a lot, whether it be for work or pleasure.

A great power bank will keep your devices powered up all day long while you’re out and about. With a compact design, they can typically be put in your purse, backpack, or gym bag with ease, making them just as portable as they are powerful.

The best part? You won’t even have to worry about recharging your power bank that often, as most have long-lasting internal batteries that can last for days before running out of power!

How much should a portable power bank cost?

The cost of a portable power bank varies immensely and depends on a few factors, with the biggest ones being power output/rated capacity and charging port type. Other things that can affect the price include wattage, lifespan, size, and weight. Some cost as little as $11, while others are priced at well over $80, with a few even nearing $100. This may vary depending on where you shop, however.

Portable chargers with multiple charging ports and port types, high wattage and rated capacities, and universal compatibility with dozens of different devices are among the most valuable options. These tend to be among the most expensive as well, though, so keep that in mind.

A few of these chargers are bulky and lack the sleek, lightweight design of more price-efficient power banks. Smaller and more compact portable chargers may not have the versatility, charging power, or lifespan of more advanced alternatives, nor the number of charging ports, but they do tend to cost less, and easier to store and take anywhere.

Ultimately, the type of portable charger you buy will depend on how much power you need and how many devices you intend to charge, as well as where you’ll be taking the charger throughout the day. Remember, though, that you can still get immense value out of a smaller, sleeker, and less expensive power bank if you know where and how to search!

What does 10K mean on a portable charger?

10K, or more specifically 10KmAh, refers to the portable charger’s rated capacity (mAh). This is the least output capacity under the rated voltage and current.

For example, a power bank with a rated capacity of 10,000mAh would have a minimum output capacity of 10,000mAh. No matter what, the portable charger will provide 1,000mA of power to your devices per hour for 10 hours (or 2,000mA of power to your devices per hour for 5 hours), unless you are charging extremely high-powered devices, or are using the power bank in an extremely hot or cold environment.

When searching for a new power bank, you want one with a higher rated capacity. The higher its rated capacity, the more power that your portable charger can supply to your smartphone, tablet, laptop, wireless earbuds, and other compatible devices before running out of juice. This will make your life easier than ever while you’re at work or on a long road trip, and give you greater peace of mind so you can focus on the important things in life.
