Voltme Hypercore 10K power bank
ZDNET’s key takeaways
- Voltme’s Hypercore 10K power bank is available on Amazon for $23.
- It’s very compact and easy to carry, with both USB-C and USB-A ports to charge two devices simultaneously.
- Its small but chunky, as some might prefer a flatter charger.
Power banks are a tradeoff: too big and they’re heavy and awkward to carry, too small and they’re pretty useless because there’s not enough charge power. I’ve found that the 10,000mAh mark is the sweet spot in terms of weight for general pocket carry.Â
But even at that size, design plays a big part. A blocky, angular power bank just doesn’t sit well in a pocket or bag. Occasionally I come across a power bank that has the right blend of power capacity, features, design, and price.Â

The latest power bank to tick these boxes has been the Voltme Hypercore 10K Pro.
I think the best way to describe the look of the Hypercore 10K Pro is “bar of soap, but without the slipperiness.” The casing is a combination of soft grippy polymer and tough plastic. The plastic is also made extra grippy thanks to the company name and debossed (cut into the material) into the side.Â
The corners are also rounded and soft, so there’s nothing on the power bank to dig into your skin or burst a hole in the side of a backpack — something I’ve had happen on a multi-day hike. That expensive, waterproof power bank now lies somewhere in the Brecon Beacon hills in South Wales.Â
Just keep in mind that it’s a little chunkier than some of the larger (and flatter) power banks that can sit flush with your phone.Â
Despite being shaped like a bar of soap, the Voltme Hypercore 10K Pro is surprisingly easy to grip.

As the name suggests, the Hypercore 10K Pro is a 10,000mAh/37Wh capacity power bank. It has two ports: on one end it has a USB-C that can handle 30W max input and output, and on the other end a USB-A that handles up to 22.5W max output. Using a 30W minimum charger, the pack can be fully recharged in under two hours.
A port on each end is quite unique in the power bank world, and I have to admit that I like this setup.

I particularly like the orientation of the ports — much better than having them on one end. You can also use both ports simultaneously or be charging the power bank using USB-C while using the USB-A port to charge another device, which is a handy feature.Â

On the front of the unit is a four-LED power indicator and a button for activating it and turning on low-power mode so you can keep your smartwatch, earbuds, or fitness tracker charged and ready for action.
One button, a single power indicator, simple.

There are no LED screens here, as there are no swarm of buttons or myriad of settings. Just simple portable power.Â
It’s also got all the safety features you’d expect from a modern power bank, from overcharge protection, short circuit protection, overvoltage protection, and overcurrent protection — all things you need, in order to prevent your power bank from transforming into a ball of flames.
ZDNET’s buying advice
I’ve been carrying the Voltme Hypercore 10K Pro for a few weeks now, and quite honestly I can’t fault it. For some, 10,000mAh is too much, others it won’t be enough, but for many, this is the sweet spot in terms of capacity, and if this is you, this is a great choice. It’s built intelligently, simple to use, reliable and surprisingly robust.
And the price is also right at $23. I’ve seen no-name power banks that look and feel sketchier for more than this.Â
