With the development of convenience, wireless charging is unmatched. You just need to put your phone on the charger and walk away. Gone are the troubles of managing cables that are inevitably broken or lost.

Not only has wireless charging improved as a technology, it has also been adopted by most major mobile phone manufacturers, including Samsung, LG, Sony, Motorola, Google, Huawei, and Apple. If your phone supports it, then you can pair it with a wireless charging dock or charging pad, so you can experience its benefits.

We have tested some of the most popular wireless chargers for Android and iPhone, and picked our favorite from these chargers. Please continue to read our findings and check our latest updates regularly.

Update on November 24, 21, including our review of the Otterbox folding wireless power bank, which is a 10,000 mAh power bank with two USB ports (one of which is USB-C), and convenient folding The designed Qi wireless charging board makes it an excellent companion to meet the needs of mobile power. Scroll to the bottom of this article to find links to all our wireless charger reviews.

Anker's PowerWave 7.5 Stand is our current first choice. It charges faster on Android than any other tablet we’ve tested, looks good, and has a stand that makes checking notifications very easy. In a quiet environment, the cooling fan in the base may be very loud, but this is not a big deal-just keep this in mind.

From the attractive fabric finish (also made of hemp and recycled water bottles) to the flexible shape that allows you to charge your phone upright or prone, to its reasonable price, we already like the Nimble Stand. Then we saw its performance! Of all the wireless chargers we reviewed, it is the fastest to charge the iPhone, and it is also commendable for charging Android. (Read our full review.)

iOttie iTap 2 Wireless is a clever combination of mobile phone holder and wireless charger.

In addition to the vent mounts we reviewed, it can also be used as a mount using the CD slot in a car audio or a dashboard mount. All three products are priced at $55 and can wirelessly charge your Qi smartphone.

The magnets included in iTap 2 Wireless are strong enough to hold the iPhone XS Max in place without worrying about it falling while driving.

In our test, compared with other wireless chargers we have tested, the wireless charging performance of iPhone XS Max and Samsung Galaxy S9 are respectively average to above average.

Until recently, you had to understand two different wireless charging standards when buying a wireless charging pad: the Power Matters Alliance (PMA) standard and the Qi standard of the Wireless Charging Alliance.

Powermat has agreed to join the WPC and adopt the Qi standard. (We have pointed out in our personal wireless charger review whether it supports the PMA standard, in case you have an old Android device that only supports PMA.) Now you only need to consider one factor when choosing a wireless charging pad: whether it supports fast Charge?

With the development of technology, the speed of wireless charging of mobile phones is also constantly evolving. You need to check the speed at which the phone can be charged wirelessly, usually expressed in 7.5 watts (W), 9W or even 15W.

Sometimes software affects speed. For example, an iPhone 8, 8 Plus, or X running iOS 11.2 or later has a charging power of 7.5W, while the same iPhone running iOS 11.1 has a charging power of 5W.

The speed of most wireless chargers is marked on the packaging. Check the wattage speed on the box or in the charger specification list, and compare it with the charging speed of your phone.

Remember, with the rapid development of wireless chargers, when you are in a hurry and need to charge as fast as possible, the chargers that come with most mobile phones will be your best choice.

In order to correctly test and measure the time required for the wireless charger to charge the smartphone from 0% to 100%, we follow the steps below every time the phone is placed on the charging pad. In the first round of testing, we used an unlocked Samsung Galaxy S9.

The procedure required to test the wireless charging pad with an iPhone is different from using an Android phone. iPhone does not have a constant light display function and can continuously display the current battery power percentage. Therefore, we chose to charge the iPhone X for 60 minutes, and then follow the steps below to measure the achieved charge level:

To get a rough idea of ​​how long it takes for your iPhone to fully charge, you can divide 60 (the number of minutes used for this test) by the percentage result listed in each comment. Therefore, if the result is an average charge of 36% in 60 minutes, the fastest full charge will take approximately 167 minutes, or 2 hours and 47 minutes.

Remember, this is an imprecise estimate: we say "approximate" because the charging speed may slow down during the full charge.

Curious about the other options out there? Below is a list of all wireless chargers we reviewed. We will continue to evaluate new ones on a regular basis, so be sure to check back to see what else we have tested.
