Be careful and measure polarity! Can damage phone! – Retractable USB Charging Cable for Nokia N70/N95/N93/N91/N90 + More (70cm) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
This is very compact and small and therefore very useful charger perfect to carry with my small 9" netbook for the case I will need to use discharged phone to connect to internet.
Cons:
BE VERY CAREFUL! I've bought 3 pieces and one of them has bad polarity (changed plus and minus). I didn't notice this and I've damaged my Nokia 6220c - because of bad polarity charging was not working anymore (neither with original charger). I had to get repair the phone.
Other:
Bottomline:
Don't rely on polarity - check it using multimeter to prevent damages: there must be 5 V, plus must be on inner and minus on outer part of connector.
