HALO CAR JUMPER PORTABLE

Even if a charger is WPC-certified, there’s no guarantee it will never have a problem, and help should be available if you need it. Maker reputation: We considered models only from companies that we knew from past experience had a good reputation for warranty coverage and customer support.If a wireless charger isn’t certified, that doesn’t necessarily mean it’s unsafe or noncompliant, but (all other things being equal) we preferred it. Safety-standard compliance: A charger certified by the Wireless Power Consortium has been tested in an authorized lab and found to be both safe and in compliance with the Qi standard.We just wanted to make sure none of the models performed far below average speeds. So although we tested for charging speed, the difference in results wasn’t particularly important. Wireless charging speed: Our tests have shown that a charger’s output level has little impact on how quickly most phones charge-that is, you don’t get a much faster charge from a higher-wattage charger.We also preferred power banks with USB-C Power Delivery (PD) ports supporting at least 20 W power input and output. For models with at least one USB-A output port, we valued those with faster charging speeds (including 12 W and Quick Charge 3.0) more highly than those limited to 5 W or 10 W charging. Charging ports: We considered each power bank’s number of ports as well as their capabilities.Capacity: More power is always better, and we especially looked for power banks offering the most battery life (measured in milliamp-hours, or mAh) for the weight and price.The thin coils inside the charger and phone transmit and receive power, respectively, when you place them next to each other, and if they’re misaligned, the connection may break and prevent your phone from charging.

Design: We considered how well the power bank was built, how it looked, how portable it was, and how effectively its surface or magnets held a phone in place.The only notable drawback is its size-at 10.3 ounces, it’s slightly heavier than our other picks. And while the Qi wireless charging pads lack the magnetic alignment of MagSafe, so they can’t easily be used in transit, both have a sufficiently grippy texture to keep devices in place during stationary charging. Its second wireless charging pad is smaller and supports up to 5 W charging-making it well-suited for a smaller accessory, such as an Apple Watch. Its main wireless charging pad supports up to 10 W charging, and the entire top surface pops up to become a phone stand that’s more stable than the built-in kickstands of most models we tested.

Its USB-C PD port has up to 18 W of charging (output) or recharging (input) power. Like our top pick, it has pass-through charging, enough capacity to charge most phones up to three times, and a total maximum output of up to 20 W. If you want the option to wirelessly charge multiple devices-say, an iPhone and a set of AirPods-the Satechi Duo Wireless Charger Power Stand is your best bet. Its combined maximum output of up to 20 W is as high as any model we tested, and with a rated capacity of 10,000 mAh it can fully charge most phones up to three times. Its USB-C Power Delivery (PD) port supports up to 20 W charging, allowing you to charge most phones (or the power bank itself) at top speed, and its pass-through charging capabilities allow you to recharge the power bank while simultaneously charging a phone or other device. It weighs just 7.8 ounces and has a compact, streamlined shape that makes it easy to slip into a pocket or small purse. The sturdy metal kickstand works in landscape or portrait orientation, making it useful as a desktop dock or as a source of backup power while you’re watching movies on your handset.

It works with any Qi and/or MagSafe device, offering up to 10 W wireless charging speeds. The ESR HaloLock Kickstand MagSafe Battery Pack (2G505) is the best choice for charging an iPhone 15 or other compatible device wirelessly when you’re in transit-whether you’re commuting, traveling, or just need a portable boost of power.
