5.0 out of 5 stars Rocked at Glastonbury 2014, 2 July 2014
Verified Purchase(What is this?)
This review is from: Anker 2nd Gen Astro Pro2 20000mAh Multi-Voltage (5V 9V 12V) 4-Port Portable Charger External Battery Power Bank with PowerIQ Technology for iPhone 6 Plus 5S 5C 5 4S, iPad Air 2 Mini 3, Samsung Galaxy S5 S4 Note Tab, Nexus, HTC, Motorola, Nokia, PS Vita, Gopro, more Phones and Tablets (Black) (Wireless Phone Accessory)
When the unit arrived it was at 70%, I tested it by letting my iPhone 5 run out completely and charging it to 100%, it charged very quickly and only took up 10% of the battery. I did the same with my girlfriends iPhone 5c (0 to 100%) and it used another 10%. I did this repeatedly until the unit got to 1% then left it for 2 weeks.

I charged the unit back to 100% the night before travelling to Glastonbury. The unit performed exactly the same at the festival - taking 10% for each charge of both iPhones, we also charged my brothers iPhone 4 but I didn't keep an eye on how much juice that used. It was such a relief not to have to queue to get our phones charged and on the very last day it was at 3%, our phones never ran out juice once (6 days in total). It lived unnoticeably in the back of my rucksack for most of the festival, survived getting knocked around by cans of beer and shrugged off the odd splash of rain.

Thank you Anker
