Details

Silicon Power products not only look good; they perform exceptionally well and the build quality is amazing too. The GS15 power bank is no exception - the stylish design packs in 20,000mAh battery capacity, features 2 USB charging ports, and a unique feature of dual inputs via micro-USB or USB Type-C. Add to that a compact design, the Silicon Power GS15 power bank is your ideal travel companion.

Go Further, For Longer
Premium battery cells deliver enough power to recharge just about any smartphone 4-6 full times, for days of power, anywhere. Superior materials within a high-quality construction make it incredibly durable yet comfortable to hold with its ergonomic shape.

Two Outputs, Two Times The Possibilities
With an impressive size-to-capacity ratio, the GS15 is equipped with 2 USB Type-A ports for dual-device charging. Both ports are engineered with our proprietary technology for smart and fast charging, making it the perfect choice for on-the-go traveling, solo or with a friend.

The Versatility Of Two Inputs
The GS15 is equipped with not just a standard Micro-USB input, but also a Type-C input. This versatility is just another reason that makes it perfectly portable. The Type-C input is also an ideal future-proof addition to sync with the growing trend of Type-C ports on devices.

Don’t Be Caught Powerless
The GS15 was designed for use with virtually any device that can charge via USB. At the simple touch of a button, up to 4 LED lights provide a clear indication of the remaining battery level, so you don’t need to fear being caught powerless while you’re away from an outlet ever again.

No complaints, charges up the phone great and still charge left in it after, it charges quite quickly too which I didn't expect, great to have as a backup when our power goes out.

Takes a long time to charge but lasts a long time too. Good size, no bigger than a regular smartphone. Very happy with them.

Bulky but worked perfectly

I went with to 20000mAh unit which is a tad heavy but sows the trick. I was travelling so the weight wasn't a major hindrance. I would suggest the smaller 10000mAh unit as its lighter and less bulky.

Good capacity, but slow to charge

Regardless of what you're if charger you use to charge this, it literally takes about 6 to 8 hours to get to 100 percent. But once charged, it's very good, lots of ports to change 2 devices at once, at quite a good pace. Not super fast charging for my galaxy ultra s22, but still fast.

Looks well made. Make sure to have a 2amp charger, it takes ages to charge.

I have purchased several of these in the past. They are an excellent balance between power and weight. I have some of the larger 20,000mAh versions but they can be a little bulky. I carry one on my motorcycle everywhere and are ideal for permanently powering a phone, especially while it is being used as a Sat Nav. Also handy or topping up a Cardo headset over a coffee stop.
