BUMP 5K Portable Charger

The 5K capacity is honestly perfect for my commute—it tops my phone up from 20% to full on the train without weighing down my bag. I’ve used it three days in a row and it still holds a charge, which is more than I expected from something this compact.

It’s small enough to slip into my work bag’s front pocket, and the 5K capacity got me through a whole afternoon of heavy navigation use without a single drop. The charging speed felt snappy, and I love that I didn’t have to hunt for an outlet until I got home.

Used it all day on a long commute and my phone went from 20% to full without the charger itself getting warm. The compact size slips right into my jeans pocket, so I barely notice it's there.
