Powerocks Stone 3 (7800mAh Dual USB Power Bank)

· · · Battery & Power

Got the Powerocks Stone 3 which is a 7800mAh Dual USB Power Bank from my cousin in Hong Kong. I am not too sure of the local retail price, but on Amazon, it is retailing for US$48.50 (S$62.50).

As the name “stone” implies, this power bank is pretty heavy (like a stone) due to the 7800mAh battery and it weighs 500g.

The build is also solid (like a stone), there are practically no openings. It felt like a solid block of plastic. It measures 7.5cm x 7.5cm x 2.7cm.

There are two input ports for charging this power bank, Micro USB Port and Mini USB Port. The charging time varies: more than 8 hours (computer USB port = 500mA), about 7 hours (USB charger = 1A), about 5 hours (quick USB charger = 2A).

There are two output ports as well, and each of this port can output a maximum of 2.1A, which is enough to charge an iPad.

The light on the individual alphabet on the logo “P-O-W-E-R-O-C-K-S” determine how much power is left in the power bank. I think the indicator is pretty nicely put, though I have to figure this out from the user manual.

  • P = 11% – 22%
  • PO = 23% – 33%
  • POW = 34% – 44%
  • POWE = 45% – 55%
  • POWER = 56% – 66%
  • POWERO = 67% – 77%
  • POWEROC = 78% – 88%
  • POWEROCK = 89% – 99%
  • POWEROCKS = 100%
