Need a simple 'cheap' powerbank. I'm looking at the $30 mark and have see 3 on Amazon (looking for quick delivery).
Common sense says the most mAh is the winner, but I'm not sure!
a) Anker A1263 – 10000mAh – 60K 4.5star reviews on Amazon
b) Anker A1215 – 13000mAh – 2K 4.5star reviews on Amazon
c) INIU BI-B41 – 10000mAh – 21K 4.5star reviews on Amazon
All are around the same age, 5-7 years old. 'b' seems like the most charge, but weirdly not even close to same reviews. Can't work out why!
Buy anything from Anker or Belkin and you won't have a problem, just buy whatever form factor you prefer. I really recommend Anker > All though.
