About this deal

It’s best to look at the main battery you’ll need to fuel up – we’re guessing it’s your phone – and work out how large of a power bank you need (of course, all phones have different battery sizes). The capacity is measured in milliamp hours (mAh) and the more you have, the more recharges you’ll get. The surface of the four-color charger is made of non-slip silicone, protecting the phone from scratching. Its size is 97.4 X 63.8 X 14.7 mm (3.83 X 2.51 X 0.57 inches), with a portable 140g (4.93oz). It also supports iPhone 12 - iPhone 13 magnetic wireless charging.

This can get pretty complicated, to be honest, but to help we’ve made sure that none of the power banks included on our list is too large to bring on a plane. Ask any frequent flyer and they’ll tell you that among their most essential gadgets is one of the best power banks – none of us ever want to be caught in a situation where our phone, headphones, iPad or Bluetooth speaker is running out of juice, and these portable batteries are the best way to keep your devices fully charged when you’re on the go. They’re not just for travellers too, they are invaluable for all your recharging needs when you’re not near a plug. It’s expensive, but you’ll pay out for the IonGo 5K Duo from Moshi if style is as important to you as is functionality.Dimensions: 10.39 x 6.91 x 2.01 cm | Weight: 223.11g | Capacity: 10,000mAh | Ports: USB-C (input and output) and wireless charging Apple has added its clever “MagSafe” tech to every iPhone (other than the SE) since the iPhone 12. It uses magnets to ensure perfect alignment for a range of accessories including wallets, wireless chargers and, of course, power banks. In 2023, there are a good number of wireless power banks on the market, and the big benefit here is that you’ll not need to worry about bringing your cables quite as much. Magnetic charging Charging is up to 15W over USB-C and 12W over Lightning. Use Lightning and USB-C together and you’ll see slightly slower charging speeds, with a max total output of 3.4A (17W).

Since the appearance of Apple MagSafe magnetic wireless charging, the excellent experience made Apple also launch a series of accessories, of which the hottest magnetic wireless power bank with short battery life and high price. Using a magnetic wireless charger offers several benefits. It provides convenience by allowing you to charge your device anywhere, without the need for plug-ins. It is also universal, meaning it can charge both Apple and Android devices without any compatibility issues. 6. What are the cons of magnetic charging? One of the disadvantages of magnetic charging is that it can have negative effects on your phone's battery in the long run. The magnetic charging cables may not be compatible with the latest lithium-ion batteries found in smartphones, potentially causing damage over time. 4. What are the downsides of MagSafe charging? EnergyCell’s portable charger is as basic as power banks get, with just a micro-USB input, a USB-A output and no support for any fast-charging standards. What’s more, it’s slow. The USB-A output is specified as 10W, but in our tests we measured the output at between 7W and 9W depending on the phone. A 15-minute charge only raised the level on our test smartphone by 7%.There was a time when power banks with LCD displays were rather expensive, but prices have now come down as the screens filter through to even affordable models like this. The Zendure SuperMini Go is something a little different: a power bank that tries very hard not to look like one. At the other end of the scale, if you need to charge a low-power device such as a smartwatch or a pair of wireless earbuds, look out for a power bank that is certified for low-power devices. Many of those that are not will simply cut out when you try to charge these devices, because they aren’t able to detect a significant drain on the battery. With a power bank, though, you can always get a recharge – even when you’re far from home. In fact, with bigger power banks, you can get away for a weekend or go camping and still keep your phone juiced up. And it’s not only smartphones that can benefit. Tablets, digital cameras and Bluetooth speakers can often do with a top-up, and a decent power bank is a must-have accessory if you love playing on a Nintendo Switch. Finally, it is important to consider the number of devices the power bank can charge simultaneously. If you plan on charging multiple devices at once, it is important to make sure the power bank can handle the load. What Else Should You Consider?
