External battery packs are an essential accessory for the iPhone, but, as we all know, they are only good if we remember to charge them. Anker, the popular manufacturer behind some of the best portable battery packs for the iPhone, has a solution - PowerCore Wireless Power Bank, which combines an external battery with Qi wireless charging. The best part is that with Amazon's biggest shopping day, Prime Day in full swing, you can get one for your home for just under $ 30.

The PowerCore Wireless Power Bank has a massive 10,000 mAh rechargeable battery that can fully charge your phone or tablet on a single charge. Along the side of the battery are two 12-watt USB-A ports that can charge or power two devices simultaneously and a single USB-C port used to charge the package.

While USB ports are handy, the real star of the show with this battery is Qi wireless charging. With Qi, simply place the compatible phone on the non-slip area in the middle of the battery to complete it - no wires are needed. While charging wirelessly, the Anker PowerCore offers up to 5 watts, and for added convenience, you can still charge other devices via USB ports.

The Anker battery also has a pass-through charger, which allows you to use it as a Qi charger always on the nightstand. With charging via transit, you will never have to worry about whether or not your travel charger has juice left, as it will always be ready to go.

With just under $ 30, the Anker PowerCore battery is one of the many iPhone Prime Day accessories on offer right now. For even more savings, be sure to check out the best summary of the Prime Day offer for all your Apple technology needs and more.
