This external battery unit is solidly built an finished in an attractive non-slip rubber finish. Whilst it *will* re-charge from a standard phone charger it takes *many* hours; a hefty charger is necessary to bring this down to a reasonable period.
On the plus side (and it's a big plus) like most of the Anker products I've bought this unit really does deliver the goods, refilling my Samsung tablet once and S4 phone twice on one charge.
Dislikes? Well the short supplied lead would charge other appliances but for some reason couldn't be used to charge the unit itself. The battery meter on top of the unit seems to light up at random with the slightest vibration even not plugged into anything. I'd prefer to see more conventional display of capacity.
Anker seem very responsive to comments and suggestions and genuinely interested in making sure their customers are happy with their purchase. This is a very positive trait ensures that I favour their products precedence when selecting new tech. (I've no connection with the company)
