Cheap but powerfulish screwdriver?

[JP_]

I currently have a £15 screwdriver, which while it works, it struggles pretty quick with screwing down my floorboards. I have a lot more to do.

Was thinking of getting something like this Bosch - https://www.amazon.co.uk/Bosch-Cord...031_1_11?s=diy&ie=UTF8&qid=1536136608&sr=1-11

do you think that will be a good enough upgrade?

there's also a Black and Decker

Nope!

I have one of these for home DIY use, it's remarkably powerful for it's size.

That's a bargain BTW, when I bought it, it was £60 and only had a 1.3Ah battery. If you have loads to do, you will want a second battery for it, too!

Downside: the batteries/tools from the blue professional range aren't compatible with this 'green power4all' range.

maybe something like this then - comes with 2 batteries

1200w its the total power the battery contains
12w for 100 mins 120 w for 10 mins that assumes no losses where as10- 20% are not unusual
this off course is up to the maximum the motor can accept and the maximum the battery can provide so probably around the 30-50w mark as a rough guess
just call it a very basic 1.2ah battery the very minimum to fit the task as in just powerful enough and may drive all the screws without going flat
better off with a hammer drill or drill driver if you have any drilling to do

I thought you said cheap?! So, what is your budget, then?

Ok, have come up with a free solution. Using the old drill. Takes a bit of getting used to, but much quicker and infinite energy. I use the blue one to get started, to save my fingers.

Whatever works for you!
Don't forget a single screw centre board screams DIY'er, thats where the pipes and cables run.

just be careful electronics dont like heavy loads at slow speed so you may blow your mains drill

Never thought of that. But I know where the pipes and cables are, so it's all OK. None go through joists, all under.

Really? Never knew that either!

Get the Bosch Blue 10.8 driver. You won't go wrong with that. Powerfull and even the 1.3Ah battery lasts for a very long time. You can get bigger capacity batteries if you want.

to be fair 10.8v has 3 times the power and capacity off a 3.6 as its 3x3.6 cells to give 10.8v
so a massive 1200w at 3.6v will now be a massive say 1300w but at 10.8v or 3times the power
i have perhaps 15 tools on the bosch blue 10.8v now called 12v including a jigsaw mini angle grinder mini circular saw and router trimmer and the performance and weight is awsome so well worth considering

Big-all, you need to re-learn your electrical maths!

to be fair 10.8v has 3 times the power and capacity off a 3.6 as its 3x3.6 cells to give 10.8v
so a massive 1200w at 3.6v will now be a massive say 1300w but at 10.8v or 3times the power

No, Watts are already multiplied by the voltage. So 1200W at 10.8V is the same power as 1200W at 3.6V.

You are confusing this with Amps. If you see something rated e.g. 10A, 10V that is twice as powerful as 10A, 5V because you need to multiply volts x amps to get watts.

1200w its the total power the battery contains

No it isn’t. The total energy a battery contains will be measured in kWh or possibly Joules.

12w for 100 mins 120 w for 10 mins

No, none of these things are ever scaled by minutes. Either hours for kWh or seconds otherwise.

after beer oclock i do get confused yes is wats x volt = amps lol
any way the point is you take any figure out off contects it can appear amazing or indeed crud

as an aside
saying " you are wrong " whilst fully correct comes across as as a bit negative
the only point i am really making is without voice or face cues to suggest a helpful comment it can be taken as negative or condicending rather than freindly and helpful
