compact, fast-charging battery

We tested Anker's new MagGo Slim 10K battery, a portable battery that magnetically attaches to your iPhone and charges it with 15W of power or 30W if you use a USB-C cableas thin as most 5K batteries but with 10K capacity to charge your iPhone twice.

At less than 1.5 cm thick, this battery has a capacity of 10,000 mAh, which is more than enough to charge some iPhone models up to two times, one and a half times if you have the larger models , and also with an identical charging speed. to what you would get with a desktop charging base, Fast charging up to 15W if you use wireless charging, but you can even go up to 30W charging if you use the USB-C port. As you can see, this is a battery with characteristics that make it almost unique if we take into account its size. The full features are as follows:

• Capacity 10,000 mAh
• Output power: 15W (Qi2) 30W (USB-C)
• Input power: 30W (USB-C) Full charge in 2.5 hours

• Size 104 × 70.6 × 14.7mm
• Weight 200g

Made of plastic with an aluminum frame, the battery manages to effectively dissipate the heat generated by wireless charging, one of the main problems with these devices. Thanks to these materials and its good finishes, it also obtains a premium appearance to which must be added its lightness with only 200 grams of weight. With the advantage of having a size similar to most 5000 mAh batteries, we will have double the capacity of this Anker MagGo Slim, and not only that, We will also have the charging power of a desktop charger thanks to the Qi2 standard. Any iPhone compatible with the MagSafe system (from iPhone 12) is compatible with Qi2, in addition to other phones from other brands, and not just smartphones, we can also charge any device compatible with the wireless charging, even if they are only compatible with classic devices. Qi, like AirPods and other headphones, even some portable speakers like the Sonos Roam.

If this is not enough and we want to charge our iPhone faster, we can use the USB-C port with a cable connected to our smartphone and we will have a charging power of 30W. Or we can choose to use wireless charging for iPhone and connect our AirPods via cable, thus charging two devices at the same time, all with a battery that fits in any pants pocket. The USB-C port allows you to recharge the battery with the same power of 30W, so we can have it back to 100% in just 2.5 hours, provided we use a charger that gives us this power . It has several LEDs at the bottom, next to the USB-C port, which indicate the remaining charge (25% per LED) and a button on the side to see the remaining charge at any time by simply pressing it, to turn off the battery or to deactivate automatic recharging (pressed for 5 seconds).
