I have two power banks. Ideal for business and overnight hotel stays when sockets are not always at bedside. On the plane, departure lounges and hidden charging when in laptop case or Filofax.
Not always the case as one size fits all but various sizes suits all.
Never faulted or failed after years of use.
It's True what they say about you get what you pay for although with anker, I believe you get more than you pay for and at a reasonable price.
Keep up the good work !
I work for a company voted top 100 in the UK and competitors try and follow us. This is the same i see Anker - a market leader.
