Power Banks from RavPower are starting to remind me of Swiss Army Knives. I recently reviewed one that acted as a hot spot, provides charging, and allows devices to read SDCards and portable hard drives. The product in this post substitutes out those features for a huge capacity (14000 mAh) and a flashlight. It has two ports. One good enough to charge most cell phones and another that is good enough to charge most tablets (1A and 2A output respectively).

I've carried similar products:

  • in the field (@ Fort Stewart and other military training facilities)
  • on deployment
  • while in Europe - kept my phone charged and acting as a hotspot for a group of 5
  • at sporting events
  • on plane trips / at the airport
  • conventions (SEMA / CTIA)
The prices on stuff like this keep on dropping. It'd probably be good to keep one charged up and in your arsenal of mobile devices / accessories.

Model: RP-PB13


(Pictured above: charged just about everyone's phone at the ball game - 2x S3, S4, LG Optimus G Pro)


Pick it up on Amazon for $42.99: http://bit.ly/18acfhG

I have the RAVPower 10400 and it's a lifesaver on my recent travels. I noticed Trent has a 14000 Rugged version so that's another option, thanks for the heads up and review on the Ravpower 14000. Is the LED light useful? Anker has it but I'm not sure how bright these lights are.

New Trent looks nice. I just had an issue with one of their products. It did get used a lot though so I'm not surprised the port finally broke.

The light is basically just enough to locate small items in the dark and plug stuff into the battery pack. You're not going to want to use the light lets say for setting up a camp site.

i'm sorry to ask here... but is the home button of your S4 blinking? how? :confused:

Abought the charger, do you notice if it loses the charge if you spend a litle time without using it? I have a power bank that i imported fron china and it loses all charge if i dont use it for 4 days...

don't think that's an S4...

just ordered two of these. great price for 14000mah for sure..

NiMh batteries will discharge fast.. LiPo and Li-Ion don't typically have such high internal discharge rates.. maybe the one you have has Nimh cells in it?

If the iPhone was at the same level of discharge and the power banks were both charged, it's nice to know that one can recharge at a quicker rate. I couldn't quote the reply that it was measuring current since that was on a different page, or I would have.

That was an Optimus G Pro =). This battery pack has held charges well just like their other product I showed in the video. Much better than some older portable USB chargers I've seen from various companies.

Ive had my Zagg for over 2 years now, with no replacement used yet. It has lost a bit of its life expansion since purchase, but I love it. Good investment for me

How does this compare to the anker one? The newest anker only lost 18% or so of the power from transferring power from external natterybto phone. How does this compare ?
