Keenstone is a smart universal charger that allows you to charge all your devices at once.
There are no cords, and the battery life lasts for 10 hours before needing to be recharged
I found 51 customer reviews as of the time of writing and they had awarded Keenstone 4.7 stars out of 5 on average with more than 40% giving it five stars!
Some users were impressed by how fast it charged their device: “The first thing I noticed was how quick this charger charges my phone”.
Other customers liked how portable it was due to not having any cables involved: “This works great when traveling without worrying about taking a backpack full of chargers”.
However, there were some mixed opinions – one user said, “It would have been nice if everything came included in shipping…it did take me awhile because I wanted all items including power cord” while others complained about difficulty plugging into their smartphones or saying they received defective products that wouldn’t work properly.


In conclusion, the only downside to this charger is that it doesn’t come with a case and some users have found it difficult to fit into their pockets. For those who don’t mind being without one though they are satisfied with the performance of this product.
