There are products too expensive for me to justify buying but I'd be happy to test. Just Anker doesn't seem to think I'm worth bothering with
Items like the Capsule II. Or if they sent me the Fusion 10000 I could at least put a meter on it and see what that 15W is actually. Or I'm intrigued by the Power Delivery Powercore products to test on my laptop and tablet. But these items are a lot of $ and may not work too well for me. The "hell why not" of a $10-$20 item doesn't really apply to a $130 PD or $349 Capsule.
