Like one of the other reviewers I purchased this neat and compact 600LCD charger to replace an old and slow Uniross unit.
The 600LCD is light weight, with the flexibility to work on various supply voltages 110 - 240V, 12V car adapter (supplied), and USB (lead (supplied). Obviously the 12V and USB mean longer charging times, but are a very useful option.
The ability to handle AA and AAA batteries on an individual / mix basis makes the unit very flexible in operation.
The 'Refresh' function will help to extend battery life and rescue older batteries as well.
I find the LCD screen a little difficult to read at times, but changing the viewing angle is all that is needed. Progress is plainly displayed for each individual battery.
I have used the unit with the 7DAYSHOP 2800mAh AA batteries and Uniross 2700mAh AA batteries so far, with excellent results. The 'Refresh' function certainly helped with the older Uniross batteries.
Overall, a well priced, flexible charger with good performance. Packaging for shipping was a bit poor though, there is the risk of damage to the unit in the post due to the flimsy packaging.
I would recommend the 2800mAh 7DAYSHOP AA batteries as well - they come in a handy little case and have performed well so far.
