Help with portable 110v battery power pack

[rvieceli]

Looking for a portable all n one unit to power from 25 to 40 watts of led bulbs for about 8-9 hours. Any suggestions?

I know I could roll my own with a deep discharge marine battery and an inverter, but I’m looking for something lighter and less hassle.

Thanks in advance.

If you have or are willing to invest in the Milwaukee M18 system, they have an inverter,https://www.acmetools.com/shop/tools/milwaukee-m18-top-off-power-supply-2846-20, and you just choose the side of the M18 battery that gives you your capacity.

The M18 batteries come in sizes from 2AH up to 12AH.

What thudchkr said...Ron

I've powered a DX 93 delta sander off of a M18 with their inverter.

[member=44099]Cheese[/member] I’ve been looking at that but there’s not a lot of Info on run time under various loads.

How long can you run the sander for?

There are tons of these- Goal Zero Yeti, Jackery, the Costco brand works well too.  All of them are also set up to receive a solar input, so you can run forever.  I run a portable fridge off a goal zero 400 for about 2 days before needing a recharge.  Ego also have a number of attachments for their batteries if you’re bought into that system.

I had a fully charged 5.0 battery on the charger in the garage so I grabbed that. Sanded with the DX on max speed and using 180 grit paper for about 20 minutes, that was pretty cool and it just got me thinking about the possibilities. This may be old news for the young-uns but for the elderly it was really neat sanding with just low voltage battery input.

I digress, at any rate, I initially checked the battery level and it was 5 LED's, after 20 minutes of continual sanding the level was 4 LED's. I was impressed...still am.

Here's a Milwaukee chart which is probably pretty accurate given my previous experience. It says that a 5.0 battery will power a LCD screen for 2 hours. That'd be close to what you want to accomplish. Even the tiny 2.0 battery is good for 45 minutes.

I have the new High Output batteries that will last even longer as they have the better cells.  I use 6 and 8s that last as long as my older 12amp.

Thanks folks. I will try and find one of those in stock. Seems to be feast or famine on inventory.

The benefit v of this over the all in one units is the ability to swap in another battery. Once the others are done they’re done.

Check Home Depot Ron...they always seem to have a couple in inventory. And inventory from one store can be sent to another.

Or order online from HD or Lowes. Often they have free delivery on items. Makes it so it's not worth leaving the driveway to burn a couple gallons of gas to get there and back.

Yup HD has them so does Acme tools. My problem is I’m at a show in Louisville this weekend and think I want it for a show in Nashville next weekend. I can’t get delivery at home until Thursday when I’ll be in Nashville. So I’m looking for in store stock along the way. There’s an HD here in Louisville that may have one. I might check this evening.

Let the games begin:

I have 6 of these lamps hooked up to the Milwaukee top off inverter. Probably in the neighborhood of 30-35 watts total. I’ve got it on a 9 ah battery. Turned on at 10 am. We’ll see how long it lasts.

[rvieceli]

Lasted until 5:45 pm. Not too shabby

Not bad Ron…almost 8 hours and the bonus round is you can always swap out batteries [smile]

The 12.0 battery should probably last over 10 hours.

Used the Milwaukee M18 Top-Off inverter to power a pair of Barrini 4 foot led strip lights. Barrini says they use 40 watts each. Milwaukee says the inverter uses 9 watts so a total drain of 89 watts. I don’t have a meter for verifying the actual load.

Used a fully charged genuine M18 5 amp (90wH) battery and the system worked for 33 minutes then shut down. The pressing the battery check button returned a single blinking led.

Expecting a 90 watt load to run for an hour from a 90wH battery would result in a completely dead battery but I expected more run time than the 55% actually realized.

How warm was the battery?  Could it have been a thermal protection cutoff, even though the battery's built-in meter said that it was fully discharged?

I also have to wonder whether or not the Barrina lights actually only pull 40W, or if that's the combined rating of the LED units themselves without taking into account the driver circuitry.  I've never put mine on a kill-a-watt to verify, though.

I ran them again yesterday evening. This time I pulled a 5amp battery right off the charger and the lights ran for 36 minutes. Charging was completed hours earlier so in both cases the batteries were at ambient temperature, mid ‘60’s.

 

[Michael Kellough]

I might buy one of these.

I ought to buy a small solar panel rig but I always loose patience before learning enough (and evaluating competitors) to complete a purchase. I have a 12 volt 18 AH SLA AGM battery sitting around and a 300 watt inverter that could be put to use. The inverter is not the (pure sine wave) type so not sure if that will work with the Barrini leds.

If anyone is comfortable enough with solar and electronic stuff to make recommendations I’d appreciate it. I don’t mind spending a few hundred but I don’t think I want to invest enough to run 15 amp power tools out there. I have enough 12 gauge cords. I just want the convenience of going out to the shed at night and switching lights on. Altitude might take throwing two switches? I understand inverters are power vampires.

I see you're looking into portable power packs—nice move for off-grid adventures or tackling projects where sockets are scarce. ️

For your setup, consider checking out options that can handle 110V like a champ. There are some solid ones out there that can juice up tools or gadgets without breaking a sweat. Think about how long you need that power to last too—could be a game-changer.

Oh, and about—those can seriously level up your power game if you're into green energy vibes. They soak up the rays and turn them into usable juice for your pack, which is sweet for longer outings.

Hey [member=297]Michael Kellough[/member] there's something here I'm not understanding. I just took these photos using the Kill A Watt. The new Barrina I plugged into it is rated at 40 watts but it drifted between 35-36 watts. So now it's an even worse condition than you described.
