Disappears in my jeans

I forgot it was in my pocket until my phone hit 100% twice on a 14-hour travel day. The OLED readout is genuinely useful.

Replaced three chargers

Dock 10 Pro runs two laptops, a tablet and every phone in the house. The per-port wattage display is addictive.

Powered our whole campsite

Core 1000 ran lights, a mini fridge and two laptops for a full weekend and still had 30% left on Monday.

Best Qi2 puck I've owned

Snaps on, stays on, doesn't get hot. Wish the cable were a touch longer, but that is my only complaint.

Airport security loved it

99.9 Wh means no paperwork and no stress. It charged my MacBook Pro at full speed in the lounge.

Tiny but absurdly fast

Volt 65 is smaller than the brick my laptop shipped with and charges it just as quickly. Never leaving home without it.

Support was outstanding

Had a question about solar input and a real engineer replied within the hour with a wiring diagram. Unreal.
