This is an inexpensive and very basic looking charger. If it does everything Shintyool says, it is a bargain. I have confidence that it will charge batteries at the stated rate. I think that this Shintyool will probably charge Makita brand 21v batteries. (Makita batteries have an additional electrical connector that interfaces with tools and with Makita chargers. I have no idea what the purposes are of the contacts in that connector.) But Makita brand chargers won't charge more basic 21v batteries, like those from Shintyool. Such batteries begin to slide onto a Makita charger in a perfect fit, but soon stop short when they hit the extra electrical connector. The basic batteries have a solid wall of plastic where the connector would be, and thus won't mesh with the connector hollows of a Makita charger. (I am uploading a photo of a Makita style battery.) This Shintyool charger does not, on the charger itself, claim any of the protective features that are claimed in the Amazon description (overload protection, overheat protection, over-charge protection, over-current protection, over voltage protection & over-discharge protection). Nor is there any enclosed literature that claims such protections. Most important to me are the claimed over-charge and overheat protections. If there is effective overheat protection, why does the Amazon page say: "[If] battery cell temperature is too high please pull out and cool for a while"? One of Shintyool's images says the same thing about pulling the battery out to cool.

I use a lot of 21v powered tools, so I have quite a few batteries, and a whole lot of single unit chargers, that just take up lots of space. I ordered this hoping to maybe put a couple of the additional chargers in a storage box. So far this charger works great, and I think I will be able to clean up some of the cord clutter and free up an outlet. The rapid charge does work as advertised, and charged up a couple of my batteries relatively fast. Another key issue is that my batteries will fit and charge on this unit (all my 21v are the same pin style, but some also have a round charging port). If this charger continues to work as well for the next several months I will definitely consider buying a second one, or see if the same manufacturer has a 4-6 battery version. Another plus is that the plug is just a normal size plug and not one of those big brick type plugs, so it really only uses 1 outlet vs the brick type that uses 1 outlet but blocks the rest from being used as well.

I've acquired a few tools that use this style battery and the dual charger was a no-brainer. Using a standard 110 AC plug, it's easier to charge two at a time and not block up an entire 4-plex outlet with the big single battery plug in chargers. I charged two batteries on this versus waiting on one of the chainsaw tool chargers to trickle charge a single battery. The indicator lights work and everything was done with no overheating. It's nice to have a spot for multiple spare batteries that can always be ready to go. There's nothing worse than having to wait to finish the job.

Works great for my leaf blower battery pack. I lost the original charging cord and when I saw this I thought I'd try it out. I was so happy to see that it works with mine. No instructions were included but is was easy to figure it out. "Green" means it's charge, and "Red" means it's charging. Worth the price and I'm really happy to have found this.

I got this charger because I have a few brands of tools that use a 21 volt battery. I checked the battery configuration carefully prior to ordering this to determine if my batteries would fit. Once I received the charger, I confirmed that my batteries did fit. My power tools came with a super slow charger that takes forever to charge the battery. This charger has more than double the output of my OEM charger plus I can charge two batteries at once. This greatly reduced my charging time. There are charge indicators on the unit. Red means charging, green means charging complete. I did not have to contact them, but the seller mentions that if you are unsure of the battery fit, that you could contact them prior to ordering. This does fit many of the tools that you find here on Amazon. I am pleased with this purchase. This charger works very well.

21v Battery Dual Port Quick Charger Base, Dual Rapid Charger I have quite a few generic 20-21v batteries that came with barrel jack chargers. This meant I had to have multiple ac adapter in to charge more than one at a time. Glad I ran in to this as it makes charging them so much easier and more convenient. I had one battery it did not work on as after inspecting the battery it did not have a lead in the slot between the two outside slots.
