The first clip-type mobile power:
Clip-style mobile power, generally is mainly used in Apple phone, Samsung and some other fashionable and slim mobile phone, clip-style mobile power commonly used polymer batteries (the exact words, only polymer batteries before easy to manufacture), due to size constraints, the general capacity between 1500-3500, in particular the decision is based on how thick the clip, in general, clip-in will not be very thick, which would also violate slim phones vision, so when users purchase more than the capacity, if not very thick, it is basically vacuity.
The second class of common mobile power,
There are square, round, anyway, have a strange, is generally used 18650 and polymer batteries, common in the capacity of around 2200-12000, in fact, this type of mobile power is our most common, now largely 1A is to maintain the output. Small-capacity mobile power may still be used to 500mA output.
The third category is a special mobile power
That is friends mentioned this issue, taking into account some special occasions, so some mobile power doing great, greatly accelerates Lynx mall to see a 30000mAh mobile power, but the price is also very expensive, nearly more than 3000 blocks. Perhaps this is not the most expensive. These are generally applicable ALICE or special circumstances. Usually the user does not buy meaning, because the capacity and volume, weight is proportional to the average user moves back one so much power, it is really steal sheep. Very expensive thing.
