Review: Huge capacity but not for the pocket - Pros This power pack is absolutely superb. Powerful, easy to use, great level indicator, plenty of ports for my needs, strong, quicker than others to charge a mobile phone, easy instructions, etc. Cons No through charging On the larger side so not a pocket fit. Maybe too large/heavy for a handbag.
Review: Brilliant powerbank - I've not had it very long, but so far it's brilliant. It charges my Samsung mobile very quickly. It's heavy, so it will depend of what you want it for. I knew that it was heavy when I bought it and that this wasn't a problem for me.
