Just keep in mind that all these products are mass produced and are subject to imperfections. Really, the only thing that matters is how good their customer support is and Anker is probably better than most but they still have a long way to go.

I say this because I had one of their USB power ports that my children use to charge their iPads (2x 4th gen) that overheated and burnt up[1]. I completed the contact form on their website and used keywords like "fire" but it took my tweet to get their attention. Even after that, their response was fairly slow. After many weeks and me even shipping the defective product back, they only offered to refund me the cost of the unit, send a replacement power port, Anker brand lightning cables (to replace Apple genuine ones - and those broke), and send me an older generation battery pack. In the end, I did not pursue the replacements because I no longer had faith in their products or brand.

After all of this, I will no longer be purchasing or recommending Anker products.
