How do you keep a digital tape measure charged all week?

The objection to a digital tape is always the same: what happens when it dies mid-afternoon. The b1 Dock answers it by taking the charging off the tool. Two 10Wh batteries sit in the dock on a USB-C cable while a third is in the T1 Tomahawk, so a flat pack is a ten-second swap rather than a tool tethered to a wall. The port on the back of the T1 still works; it just stops being the only way to get power into the thing.

The video runs through the b1 Dock: a USB-C cable in, two batteries charging side by side, then one popped out and dropped straight into the T1 and the tool powered up. The whole point is that the tape never has to sit on a charger. The batteries do, and the tape keeps working.
