Those of you who follow the site ay remember me reviewing the Enerplex Packr Solar Rucksack. It was the bag I took to MWC 2015 with my and it proved to be very useful as it was able to carry a ridiculous amount of gear and was still pretty comfy. the only thing missing was a battery pack for the solar panel to charge. Well Enerplex have just sent me one of there new Jumpr Slate 5k battery packs.
We have a 5100mah pack here in a very slim form factor, it is not much thicker than the size of a USB port. The battery is very light as well and is vibrant with a contrasting grey and orange colour scheme.
Hardware
On the bottom of the pack is where we confined the USB for providing power out to non Micro USB devices i.e. iPhones or iPads.
Next to that is the Micro Usb input for charging the battery pack.
Next to this is the power switch to ensure that the pack is turned on. You can also use this to check the reserves of the battery when on the road.
Lastly their are LED indicators showing from Max to Min.
The only other distinguishing feature is a bright orange Micro USB cable on the right hand side. This will allow you charge phones and tablets meaning you don’t have to worry about bringing a cable with you, one less thing to worry about thankfully. The battery also features cut outs for those who wish to include this in a filofax (who uses these!)
Usage
In use I have found that the supply will give my Xperia Z3 a full charge with enough left over to give me a 50% charge to my Xperia Z3 Compact tablet. Where it is really useful is in conjunction with my Remix Ultra tablet as this can charge via a Micro USB as well meaning that, I can keep it going whilst on the road. Recharge times for the pack are not that bad I found that I could charge it back up again in a few hours from the Xperia Z3 charger which is outputting at 5V. 
As a blogger who does most of his work in a mobile office (train) I need to make sure that my kit is fully juiced at all times. This battery pack will allow me to do that without feeling the burden of carrying a huge amount of extra weight.
Summary
I am very pleased with the Enerplex Jumpr Slate and it is now a permanent item my kit bag charging my devices whilst I am getting around. I have used it charge my Phone, my Smartwatch, my Remix Ultra and my smaller tablet. I was even able to charge my camera lens (QX10 from Sony) from the Jumpr as it is a Micro USB device. In fact the only thing I have not been able to charge from the Jumpr is my Macbook Air as this cannot be powered by Micro USB. However with more and more manufacturers looking to use Micro USB 3/C this will be possible soon (can be done on the new Macbook). If you are wanting a light weight and portable power solution then check this out for £49.99 on Amazon now. You won’t regret it!
