Impeccable battery identical to the original. super convenient for external charger to recharge the battery without the phone. There is a USB plug on the charger to charging at the same time or another such tablet. useful for small precision battery charge because there is no Record: bright purple witness when the battery is charging and goes blue when the battery is fully charged. The charge appears effective but may take a few hours.
For the adapter UK I have not the utility but it can be practical Travelling.
Very good useful and practical product to always have a battery Relief charged bypassing the such. That way I always 2 batteries charged. I highly recommend especially for the price.
