Brilliant Battery Extender!
on 1 March 2011
This may not look the nicest, nor may it give the most protection, but if you're unsure if the battery on the iPhone 4 is going to be sufficient for your needs, this is definitely a well-worth investment.
Currently priced at over £60, this product originally retailed for under half that price, and I'd recommend shopping around as at £30, it's a snip. The phone looks slightly bulkier, but you can charge up to around 70-80% battery power, perfect for an emergency, and it's also very, very fast. It fits nicely onto the iPhone, and you can tell it when you want to re-boost your battery.
Overall, a very, very useful product!
