40V Lithium-ion 2-In-1 Battery/USB Charger
40V Lithium-ion 2-In-1 Battery/USB Charger is rated 4.8 out of 5 by 369.
Rated 5 out of 5 by from Lightweight and compact! I purchased the Ryobi 40v power head with string trimmer because I could attach other tools to that particular model. I was hoping for the strongest battery I could get but never gave the charger a second thought. I’m glad Ryobi did! The addition of the usb charger is handy in the field to charge my phone and other electronics, and the charger itself is lightweight, compact, and durable. It takes virtually no space in my vehicle storage bins and fits on top of the batteries so it’s even less likely to get damaged while charging. Ive been very pleased with my purchase, and plan to buy an additional charger and battery in the near future.

Rated 5 out of 5 by from great battery life This battery and system (I have the 500 CFM Jet Fan blower and the 20 inch cordless mower) replaced an 80 volt system from another manufacturer. The mower and battery combination does the front, side and back yard for a two owner condex, with 50% battery remaining, and the blower, even with occasional use of high speed, lasts with dry leaves for the same area, though using more battery. Given that this is a second battery, there's absolutely no need for gas equipment at all. Its a small yard, but given that the mower is only half discharged, this says a lot. The previous 80 volt (heavier also) system needed two batteries to do the same amount of work.

Rated 4 out of 5 by from Lock and load I bought this a month ago, but I owned the previous model. The previous model stopped performing after 2 years of use. It would randomly shut off with full charge and would stop working. I have the blower attachment (love!!), the weed wacker, and the chain saw (saved me hundreds in tree trimming and hours of time). I didn’t want to waste the investment I made in the attachments, so I tried and failed to get Home Depot to take mine as a return. I eventually grabbed the new model and it is working well. The only issues I have are that the part where the battery hooks into (not the actual battery) gets quite hot during use and that the battery takes quite a while to fully power up for longer uses.

Rated 1 out of 5 by from Terrible all around Bought this two weeks ago from Home Depot. Used it once, worked fine. Then never worked again. Called customer service and was by far the worst experience Ive ever had with a customer service Department. Heidi was the name of the person who fielded my call, could not care less about my issue or attempting to keep me as a customer. She seemed bothered I even dialed the 800 number. First and last time I buy Ryobi for that reason alone. Not the product, the way they treat paying customers.

Rated 5 out of 5 by from Easy. Dependable. Purchased the 40V Lithium-ion battery-powered Lawnmower, Blower, and String-trimmer one month ago. Small yard. So far: LOVE all three. The Lawnmower is easy to use, does a great job, and folds up into a very compact storage size. Blower and string-trimmer also great. Some on-line users reviewers have complained about short battery time. My battery time is outstanding. All these tools came with and use the same battery. I anticipated a battery problem, so l made sure I would have backup. Have had to use two batteries on only one lawn mowing. Take one battery out, replace with fresh battery. Took about 30 seconds. As not4d, only a month in, but I would recommend this set to anyone with a small to medium sized yard.

Rated 3 out of 5 by from It works Came with the string trimmer and 4amp battery combo. It is pretty small and has a power adapter with a proprietary plug. Why proprietary just makes it a pain to replace. This charge you put onto the battery as opposed to the larger charger where it has feet and you plug battery into it. Not sure what the usb charge port is all about - seems out of place for lawn equipment. Charged the battery from empty to full in just an hour or so.

Rated 5 out of 5 by from Portable and convenient This came with the 40v chainsaw and I'm very happy with it. We have other 40v tools for a few years now, and this charger works on all the different 40v batteries in our collection. Although this charger cannot be wall mounted, it is more protable than the larger chragers that came with our other 40v tools. This also has a built in USB port, which can be used to charge other devices, from either the AC wall plug, or from a connected 40V battery. And yes, that means you could use your Ryobi 40v batteries to charge your cell phones, if you really needed to!
