I have the older solo 9 20 000mAh one.
much bigger than the sailing 6, a friend in the office has one of those.
and other than the 13 hour charge time (to be expected honestly) there is no complaints.
wife has a different brand 10 000mAh power bank, and honestly even though its much more portable its just not worth it.
get Romoss.
I would actually want to get another, smaller one.
the idea is, have the solo 9 in a bag, so when I am at a desk, or table, plug it in and charge everything. but when I am walking around playing Pokemon go, have the smaller size one to keep the phone going while being able to walk, the solo 9 does not fit comfortably in the poket, and you look like a twat.
if anyone spots any god cyber monday deals on Romoss Products, please share them...
