Verified Purchase(What is this?)
This review is from: Anker Astro Slim3 6000mAh Ultra-Slim Portable Charger External Battery Power Bank with Built-in Micro USB Cable for USB Devices (Black) (Wireless Phone Accessory)
Impressed with this product. To hold that much juice in such a small space is amazing. Charging output is very impressive too at 1.0A so it's a fairly speedy charge.
Does take a long time to charge up but that's to be expected at 6000mAh.
Taken away one star as it feels like it's losing it's juice over use. When i first purchased it was able to comfortably fully charge my device twice from close to empty. But after a few months use it's a bit short of being able to fully charge it twice.
Still, it's very useful as I can charge any device with a compatible port on the go. Great to use on holiday too when you're not near a charging point for very long periods.
