RavPower 6700 mAh Battery Bank Review

Categories Battery Banks

Rating: 4.5/5

What I Like: 

  • Solid feeling metal build
  • Good charging speed
  • Recharges self quickly too
  • Compact pocketable size
  • Doesn’t heat up much when charging/discharging
  • Includes a padded carrying bag

What I Don’t Like:

  • Only little lights instead of a proper percentage readout
  • Battery longevity is questionable

Conclusion:  This is one of the better chargers I’ve received recently. While it isn’t Qualcomm quick charge certified, it outputs about the maximum my phone can handle and it manages to charge my phone fast as I can get without it being quick charge certified. My 3,000 mAh LG G4 manages to recharge itself just under 2 times while not in use, indicating approximately 85% efficiency, which is expected from a battery pack like this (here’s the math: 6,700 x 0.85 = 5,695 / 3,000 = 1.9). If you want to see how many times it will recharge your device, consider that after efficiency is taken into consideration, the ‘true’ amount of power this pack will output is around 5,700 mAh. So if your battery is smaller than that, you will get at least one full charge (assuming you do not have your device turned on during this charging process. Of course, using your device during charging will use more power). Unfortunately the power remaining readout is just simple LEDs. I wish it was an actual screen as to me that adds a lot more value. This charger would be something to recharge after every 2 uses or so depending on the type of phone/device it is being used with. In terms of build quality, I’m particularly fond of the rounded metal build. The charger is small enough that I can slip it into my pocket. It includes a little padded bag too, which is good because I’m afraid of scratching my device on the metal edges if they end up in the same pocket or backpack. Overall this charger works well and is a nice compact size.
