Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways. Energizer is no stranger to energy storage and other power-related products, and most of its offerings are high quality. So, if you want a small power station to keep your mobile devices and some low-powered gadgets running during an outage or on a camping trip, the company's PPS320 is worth considering. It's one of the most affordable power stations among our recommendations and features a 320Wh LiFePO4 battery, which will deliver 300W of power. Wide Compatibility: Supports Power Delivery charging technology and works flawlessly with a wide range of devices such as laptops, phones, tablets, and more. One of the few power banks capable of delivering 140-watt power, the Anker 737 is a very powerful power bank. It weighs in at nearly a pound and a half and can deliver the power you need to keep working through a layover, power outage, or any other situation where you need a lot of power right away. Anker's power banks generally do what they aim to with relatively little extra. For example, the brand doesn't have any power banks that also support wireless charging or any other exciting features.

High-Speed Charging: 30W USB-C charging gives you the power you need to charge up your iPhone 13 to 53% in just 28 minutes. You can always buy an extra cable to charge up your power bank, but we just find it useful to only have one type of cable, so if your phone supports USB-C charging you'll likely want to find a power bank that supports the same.This power bank is capable of charging up two power-hungry devices at once. With enough stored power to charge an iPhone from empty to full 4.8 times, this potent power bank is the perfect solution for weekend getaways and remote workers.

Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide that can give you an estimate. A power bank is not the same thing as a portable power station. Portable power stations are much larger and typically meant to be used in emergencies or to power small appliances while you’re away from your home’s power– like say, a box fan while you’re car camping. Power stations are also often used for campers, power tools, car camping, and other heavy power needs. A power bank is meant to hold a comparatively small amount of charge and is not meant to power anything larger than a laptop for any extended period of time. There’s a good reason the GH Tech Team added this model to our list of the best power banks: it gives you a big capacity without the size (and high price) of the more imposing Anker 737, although if you do fancy it, there's a 36% on that model, too. Not only can you charge three gadgets at once – ideal for refuelling your phone, earbuds and Apple Watch simultaneously – there’s enough juice inside to deliver seven charges to an iPhone 8 or bring a more recent iPhone 13 to 50% in around 40 minutes. That’s impressive. Capacity:Think of capacity as the energy reservoir of your power bank. The higher the mAh (milliampere-hour), the more power it can store. So, choose a power bank with a capacity that suits your charging needs and can juice up multiple devices.This is self-explanatory, but some of these batteries get pretty boxy and chunky. The dimensions and mass matter, as we assume you’ll be bringing a portable charger with you for the day.
