Charger Improvements and Gen 3 handheld blower

A lot of people on Home Depot and the EGO product website have posted reviews indicating problems with run time, especially people who purchased the backpack blower, and I believe that I have a solution for them. Upgrading the battery without changing the cost will be difficult, but upgrading the charger will be easier. If you use cells that are rated for a maximum discharge current of 35 amps or 50 amps, you should be able to create a 12 amp, 1440W charger capable of charging 2Ah and 2.5Ah batteries in 10 to 15 minutes.  With something like that, you could consider letting the current rapid charger become the standard charger and letting the 12 amp charger be the new rapid charger and complaints about run time would subside quite a bit. 

Also, as a guy going pro with electric equipment, I find it a pain to have to either use another hand to adjust the power of any of the handheld blowers or to have to flick it up to get my thumb all the way to the dial. A thumb console comparable to those on the 80V blowers would be preferable. Also, the LB5300 puts about 16 Newtons of force. In order for a Gen 3 handheld blower to put out more force, say 20 Newtons, without the thrust fighting the wrist, the blower will need to be back heavy. I find it much easier to use my thumb on the 80V blowers to push the front down than I find it to use my wrist to pull the front of the EGO handhelds up. With the blower back heavy, when it ramps up to full power, the thrust would balance the back counterweight, keeping the blower from fighting the wrist. Theoretically, if a heavy counterweight is needed and it compromises the ergonomics too much, then the weight can be made adjustable, being able to be moved closer to the pivot point, the hand, to decrease the leverage on the back, or moved away, increasing the back heaviness by leverage. This would be adjustable ergonomics for you and would be needed for a 600CFM, 135mph handheld. I talk handheld blowers because if one were to want the power of a backpack blower, he or she could just buy a pair and use the two simultaneously, so selling a box with two blowers, two batteries, and two chargers for that purpose might be ideal in place of a 1200 CFM backpack blower.  

A sidenote, I'd suggest using the same dial system you have, but put it somewhere the thumb can easily access so one could more easily wield and control two blowers.

Charge time and long term battery life are inversely proportional.  Ego, like Tesla, has a done a good deal of engineering to control discharge/charge temperatures.  Forcing that much current into the cells in a short amount of time will be counter-productive to that engineering effort.

Personally, I would vote for increased battery life, over a 15 minute charge time.  Which is also why I chose to NOT drain them until the led is RED; and also why I let them cool to room temperature before re-charging them.

I forget which video it was, but the guys at Tools In Action were saying that despite the "homeowner" grade marketing they would put Ego's tools up against any battery tools they've seen.

Maybe we'll see a commercial grade lineup of Ego tools in the future? The batteries are there already, they would just need to beef up the tools to deal with commercial level physical abuse.

Actually, interchangeable control systems to attach to the front of the handle of the blower, one traditional EGO attachment, a control console like that of the 80V blowers with buttons to control power, and a lever system like those on gas blowers, cruise control. Each user can attach whatever control system he or she prefers.

The sad part about building a tool line.  You cannot build a line that will please everyone, but it sure is possible to build something that will please no-one.

EGO had done a great job to try and catch the middle to upper end of the home-user (prosumer) spectrum that partially overlaps into the professional camp.  When you look at  Stihl and Husqvarna they are in a much more difficult place in the pro-line is just to costly for the home user.  The price is partially justified by the material costs to make it better, but also because the size of the market is small and requires that price to make is cost effective.  Now both these makers have tried to make something into the prosumer market, but have a harder time in what do you cut out not only to bring down the manufacturing costs, but also not threaten the pro-line tools buy undercutting yourself.

The batteries by EGO are the big selling point.  They are extremely well designed and made.  They have a great recharge tech and scalability in implementation between multiple tools.  Buy into a big tool and it just makes sense to keep to the line.  Everything is good enough for it to be a no-brainer.

In the pro line, it gets very hard to get the synergies as a battery designed for a large pro mower it just too much overkill for a hand held blower, or an edge trimmer.

Don't forget the importance of profit margin. To occupy a space in Home Depot, a product has to make them lots of money.

This article was linked a while ago; here it is again for those who may not have seen it. Note the line about profit margin:

They said in the video thumbnailed "Big EGO" that they'd pit it up against Stihl any day, and the blowers are stronger than Stihl's, but they're about the same as Greenworks.

The biggest take from this is the thumb throttle dial.  I love it on my Makita backpack blower.  Set it and forget it.  Get to work.
