I have been using RichardSolo 1800 for quite some time now and all I have to say is it packs quite a punch when it comes to holding the charge and charging the iPhone efficiently. Mophie juice pack performed great when it came to performance and the real winner may be decided on the design. RichardSolo, despite being compact had a terrible implementation. Just imagine using an iPod Nano to charge your iPhone! The connection can be very unstable since it is latched at the end of the iPhone and it can be a real pain when it comes to charging the iPhone while On-The-Go! Mophie Juice pack on the other hand graciously doubles as a hard case offering some protection and the much needed juice to power your iPhone 3G!

RichardSolo comes with a wall adapter, a retractable USB cable and a car charger which may be great additions and the price tag of $69 may be perfect given Mophie’s $99 tag.
