Customer reviews
I took this on a three-day camping trip and it kept my phone and headlamp battery pack charged the whole time. Charges two devices at once without slowing down noticeably.
Does exactly what it promises, charged my phone almost five times before needing a recharge itself. Only downside is it's a bit heavy to carry every day.
Been using this for six months now, still holds charge well overnight. Wish it had USB-C input but the micro-USB cable included works fine.
When our power went out for two days this kept my phone and my partner's phone running the whole time. Excellent value for the capacity.
The power bank itself takes a long time to fully charge from empty, which caught me off guard before a trip. Once charged though it performs great.
