Buy it on Amazon here. I'm currently talking with their support team about getting discounts for all you guys, I'll know more soon! This charger is a great deal for $30, as you're getting quite a lot of capacity for your money as you can charge an iPhone 6 at least 6 times. The trade off you're making here is the comparatively smaller current and the two ports delivering different amounts of current, but if you're buying more than one battery bank then there are discounts to save 30% on some of their other products. This weighs 1 pound, has a 24 month warranty and is a pretty decent pick if you don't need the absolute fastest charging speeds and the digital screen is nifty.I'm currently talking with their support team about getting discounts for all you guys, I'll know more soon!

It's an absolute nightmare to run out of battery right when you're catching up to a hefty charizard. Most of our wonderful smartphone addicted generation will already have a battery bank (or just carry a charger around in their bags), but if you have just discovered the joys of running your phone down to 0 in a day because of Pokemon Go, then here are the best external battery packs you can get. If you're a British trainer, take a look here . Also you can get a pedometer for 20% off if you'd like an easier visual of how far you've walked.This monster isn't for the fainthearted, it has a combined 5.5A output across three ports so if you've got a group of friends out there capturing pokemon you'll be able to all charge your devices. They have offers for a discount ofand in theory code ALX97E29 will bring the price down to $40. It is just under an inch thick so it isn't too bulky to carry around in comparison to some of the other heavy hitters in the market. It includes 2 Micro-USB cables so you can leave one in your PC and one in your bedroom etc. It is glossy and has anti scratch treatment so it will stay looking great,. I've asked them if they can do a discount for my readers as it is a bit pricey, but its worth every cent! Anker are known for their great products and it shows in this really well reviewed battery pack with 4.8 stars over 733 customer reviews. This is smaller than a pack of cards and charges an, it includes Anker's exclusive PowerIQ and VoltageBoost which combine to give very fast charge for any device. This package includes a travel pouch, micro USB cable and their ace customer service. They use premium materials - world class chips and cutting-edge circuitry and they have a safety system to provide surge protection, temperature control and more. Anker are just an all round amazing company. This battery bank has the highest output in the market for charging 3 devices, with 5.8A that can simultaneously charge 3 devices for 2.4A per port. It uses iSmart technology that will automatically detect and deliver the optimal charging current for connected devices. It may not be the most attractive power bank but it packs a punch and is currently discounted from $90 to make it look like a great deal.This sleek leather look powerbank is a really great deal on sale for, it has a capacity of 10000mAh which is enough for 2-3 charges on an iPhone 6s Plus which is decent if you aren't a heavy user and you're happy to recharge it frequently. It has a slim design and it is fairly lightweight, fitting easily into a pocket (0.5 inches thick). This is best if you usually just grab your phone and a snack and head outside for a while as you don't need a bag to carry it (unless you're in a dress without pockets), it is pretty easy to hold as well if you don't want to put it in your pocket while you catch em all. You will need to recharge it much more often, and it doesn't carry as great customer service as Anker so it depends whether you want to save $4 (you lose a long warranty). I tried to contact them regarding discounts and didn't actually find their support team.
