I would like to prefer to describe a practical case, why this product stands compared to similar products from other manufacturers out:
I work at the European Space Agency (ESA). At our last start unfortunately occurred unexpectedly on issues that do not have our ground technicians readily solve. A sudden power drop in the cockpit power supply threatened the entire project to fail pleadings.
At the last moment a lot of my "anchor 24W Dual Port Rapid USB" one, I always have been doing as a precaution. Now the countdown has already counted down ... there was no time to lose and take action!
I hoisted myself from my co-pilot's seat during my hand at the same time sought the way into my pocket and got to grab the "anchor".
Quickly I was at the hatch, and then outside. Now, everyone knows that a rocket (Ariane 5) with a height of 54m is not exactly small ... so I stood on the platform and did not know how I should come soon enough to the ground. A look at my "anchor" brought the solution ... and I can say the thing "is" not only anchor!
So I jumped off the platform and put in the jump the cable in my "anchor". An aimed throw my anchor to the support rod near the ground took the rate of fall with a loop around the rod and let me gently like a cherry blossom in late summer to land on the ground.
With a few steps, I was on my monster truck, stuck my "anchor" in the board socket to my battery (Model: Plutonium Fuel Rods Tripple) to use as a starting aid.
Fortunately, the technicians of the Ariane 5 have really thought along, and an ultra-USB 93.0 (not yet available on the open market) at the foot of the missile interface integrated. The charging of the missile was completed in 378 milliseconds and the cockpit instruments functioned perfectly again.
Unfortunately for me it was no longer possible fast enough to get into the cockpit, so I just closed my visor, and again relied on my 'anchor'. I let him simply inserted and used in the wake of the rocket, the view while climbing in the exosphere. The re-entry into the rocket was in space quite problematic, since often practiced.
By the way, the "anchor" part from that day to the basic equipment of every astronauts and ground technicians.
Therefore, from me: Full buy recommendation for stationary and Interstellar use.
