'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

Powertraveller Sport 25: Ruggedized, water-resistant IP67-rated power bank
I have a lot of power banks, but it's rare to come across a power bank that claims to be water-resistant. It's even rarer to come across a power bank that is actually water-resistant.

Powertraveller Sport 25
Here are the tech specs:
- 6700mAh/24.8Wh capacity
- 5V/3A USB-C input and output
- 5V/2.4A USB-A
- IP67 rated
- 150 lumen flashlight with SOS
- Ruggedized shell
- Weight: 187g
- 4 LED battery level indicator
- Comes with 1m USB-A to USB-C cable and USB-C to microUSB adapter
The Sport 25 is quite a bit bigger than other power banks of its capacity, but the ruggedization adds bulk, which is a trade-off I'm willing to make.
The IP67 rating means that it is fully protected from dust and can be submerged in 1m of static water for up to 30 minutes. I've tested this, and the Sport 25 shrugs off water like a duck.
The flashlight is nice, and the single button easy to use, even when wearing gloves. Although, since the Sport 25 includes an "automatic on" and "automatic shut off" feature, you don't need this that often.
In my testing, I have come across one problem with the Sport 25. I can't use the USB-C port to charge my iPhone. Even using a genuine cable, the charge cuts out within seconds. I believe this is down to the USB-C port not being Power Delivery compliant. I can't find any other device that has a problem with it, and I can use the USB-A port for my iPhone.
A nice power bank at a decent price.
