  • Works very well

    from Vancouver BC on 6 avril 2019

    I’m on a boat in the Aegean using my iPhone to search the web and the battery charger has recharged the battery while I’ve been working. It charges easily itself and has twice now fully recharged my phone and still shows at half charge itself.

  • Still doing it's job!

    I bought this product over a month ago. Been using it almost far I never had any problems with it. Yes, it's plastic and looked cheap but hey...what good does it do if you have an expensive looking power bank but stopped working on you after 3 or 4 charging??? You won't hear me complaining as long as it's still doing it's job!

  • Do not buy

    Frankly, crap product. Won't actually charge my phone - it just holds the battery steady or charges so slow it's effectively useless. Only re-charges about 20% of the time. I need to give it a week-long timeout so it will take a charge. I got a dirt cheap one from my work that does a way way better job than this. Save your money, buy something else
