This is a REVIEW of the article with description: K&F Concept LP-E8 Battery and Dual Slot Charger for Canon 700D 650D Rebel T5i T4i T3i T2i Kiss X5.
This is a good pack of 2 batteries and dual charger compatible with CANON photography camera formats that use the LP-E8 model, it is powered through a USB-Micro or USB-C port with a 5V power supply greater than 2A (not included), but simultaneous charging of dual batteries is a bit slow, the average simultaneous charge is 0.7-0.8A (about 0.35-0.40 for each one) while independent charging if that 0.7A current is used for the one you have connected.
Post-charge performance is good, similar to the original batteries (which hold 0.80 mAh less charge), and the camera's locking and charge level recognition are good. The camera correctly indicates a low or near-low battery level, ahead of shutting down due to a power shortage.
They fit well into the charger; they snap vertically onto the charger and are firmly secured. They require a firm pull to remove them, so they are not easy to disengage or lose their connection, whether by tipping over the charger or getting caught on the power input cable.
The only drawback I can find is that the charger doesn't have a display or level LEDs to indicate the different stages of the charging process. Only the LED corresponding to the charging bay turns red, and you have to wait until it turns solid green. Sometimes you even take out the battery to check the charging status in the camera, when it's red, and when you put it back in, if the camera indicates that it's already charged, the charger already shows a full charge in green, as if the final charge check weren't very accurate.

My rating for this pack, especially considering its good price and the reliability this brand usually places on its products, I have decided:

4 Stars = ( * * * * ). I hope you find this review useful.
