Promate Mavrix-20 20000mAh Transparent Smartphone and Apple Watch Power Bank - Black / USB-C & Lightning Cable / 65W PD USB-C Cable / 12W Lightning Cable / 27W QC 3.0 / USB-C In/Out / Mavrix-20.Black / Mavrix-20.Black

The Promate Mavrix-20 is a 20000mAh power bank in a clear tempered glass body, built to keep phones, tablets and laptops running through a long journey, an office day or a weekend away. It carries a built-in USB-C cable, an integrated Lightning cable, a magnetic Apple Watch module and separate USB-C and USB-A ports.

The Mavrix-20's built-in USB-C cable carries 60W Power Delivery, which is enough headroom to charge laptops as well as tablets and smartphones. Because the cable is part of the pack, there is nothing to unpack or plug together first, so a laptop can be back on charge within seconds of taking the power bank out of a bag.

An integrated Lightning cable is fitted to the Mavrix-20 for Apple devices, so an iPhone, an iPad or any compatible Lightning device charges without a second cable in your bag. It sits alongside the USB-C cable rather than replacing it, which means a mixed Apple and USB-C household is covered by the same power bank.

A magnetic Apple Watch charging module holds the watch in precise alignment and charges it at 3W while you are on the move. It is compatible with all Apple Watch models from Series 3 through Series 9 and supports every case size from 38mm to 45mm, so you place the watch on the pack and leave it.

The 65W Power Delivery USB-C port runs in both directions: it refills the Mavrix-20 quickly from a wall charger and, in the other direction, feeds high-demand devices such as laptops, tablets and smartphones. That single port is what lets the pack recover between trips instead of spending a full night charging.

An LED display on the Mavrix-20 gives real-time data on the remaining battery level, so there is no guessing about how much charge is left before a flight or a full day out. Knowing the exact figure makes it straightforward to decide whether the pack needs topping up or will carry the rest of your devices.

The Mavrix-20 charges up to four devices simultaneously while staying lightweight and easy to carry, which is the point of having built-in cables rather than a bundle of loose ones. Its rugged, compact construction is made for adventurous trips, so it handles being thrown into a pack for a road trip or a hike.

A 27W USB-A port handles everything that still uses a standard USB plug, including smartphones, tablets and cameras, with strong and reliable output. The clear tempered glass shell is the visual signature of the Mavrix-20, putting the internals on show in an elegant black finish rather than hiding them behind moulded plastic.
