What our customer's say!

"Good Product", It's great to have an additional battery ready for those big jobs. Just don't order it from Kooltron; they have the absolute worst service that I've ever experienced from any company.

"A great assistant for your Roomba", A must have for Roomba (4th generation & earlier) owners with 2 or more batteries. Helps to keep the second battery charged while Roomba is working. In addition, its also useful for conditioning old/new batteries, works better than the 72hr charge on Roomba itself.

"Very Handy and good price!", Easy fix for a bad charger circuit on the Roomba main board. Very handy when you have extra batteries to keep charged.


"External Roomba charger", This is an external rapid charger for Roomba batteries. Since failure of the charging circuit within Roombas is a common problem this is a way to keep your Roomba running after the failure. It does recharge the battery in about 3-4 hours.

"Roomba Rapid Charger", A great saviour for those Roombas whose battery charging circuit failed them.
