About this deal

You’ll have noticed that we list the battery capacity in milliamp hours (mAh) throughout this roundup, and it’s worth using this as a guide to the charger size you’ll need. The bigger the number is, the more capacity it has. Of course, phones all have different batteries too. Nearly all batteries include a standard USB-A port (output). This is for plugging in USB-A-to-micro-USB, USB-A-to-Lightning, or USB-A-to-USB-C cables for charging your iPhone or Android device. 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.

Look for a power bank with safety features such as overcharge and short circuit protection. All Anker power banks are going to have these basic safety features as part of their MultiProtect safety system.Additionally, Anker uses fireproof cases and has built-in temperature monitors that keep your device from getting too hot. Larger power banks can easily get too hot and have even been known to catch fire; Anker’s dedication to safety means that this is not such a risk with their products.

Power for 4: Equipped with 2 USB-A and 2 USB-C ports, the portable charger is ideal for charging your laptop, phone, tablet, and earphones. With 2 USB-C and 2 USB-A ports, the portable charger delivers powerful and high-speed charging to up to 4 power-hungry devices at the same time. Charge it Fully: Plug in your power bank and let it charge fully before using it. This ensures that it's ready to provide a reliable power source when you need it.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. Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB. As a company, Anker is known for its reliable products. Starting as a replacement laptop battery company in 2011, Anker swiftly rose to the top of the industry for power banks, cables, and other similar products. Anker focuses on creating mobile power management solutions and accessories that work with a wide range of products. 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. The QiSa Solar Charger can use the sun to recharge itself, supports both wired and wireless charging, and even has a built-in flashlight. Best of all, it offers a massive 38,800mAh capacity. Who It's For

Design-wise, they're roughly as interesting as TV remotes or tin openers. But you need one. You may need two. And you need them to be decent, or one of these days you're going to find yourself on one percent, beached, trying desperately to find a crumb of charge somewhere.The number in the title of the power bank usually refers to the capacity of it, so the PowerCore 20000 for example features a 20,000mAh battery.

You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common.

In terms of ports, there are four AC outlets to power home appliances or anything else that needs AC power. Each is rated for 1800W, but remember that's also the continuous power output limit of the unit. You'll be happy to know the company also includes a grounding port. For DC charging, there are four 15W USB-A ports, a single 100W USB-C port, and a 12V DC outlet. Moreover, a Qi charging spot on the top can push up to 15W power to your phone or wireless earbuds.
