185Wh Battery w/ charger for only $135

Pretty good deal IMO - This is over 3x as many Wh as the Naztech PB15000 (which is a 55.5Wh battery)- i.e. will last 3x longer!

It has 20V, 12V and 5V outputs.

Looks like a good deal.  The big plus of the Naztech is the adjustable voltage, and this one has only 3 fixed levels.  But that seems like a decent trade-off for the much higher capacity. 

What would be really nice to see in a future product like this would be to make the 20V and 12V outputs each adjustable over a range, while leaving the USB outputs fixed at 5V at the two different standard current outputs.  I'm thinking of powering two different pro recorders or a recorder and preamp, each at 12V or 16V from the same battery, eliminating the need for a distribution box.  I'm sure that total output current would be the limiting factor, so this may be a fantasy device I'm thinking of.

Any feedback on these? My old BatteryGeek 10-14-115 bit the dust and I'm afraid the other is not far behind.

I bought one about six months ago. I've run 2-5volt decks and a fairly thirsty preamp simultaneously and over the course of a standard show it doesn't even drop the capacity meter one light. It doesn't seem like cheap junk like alot of the batteries out there. It is a bit heavy but still lighter than a SLA. I shut it down early during an initial test because I was confident it would last 24 plus hours straight. Check your current draw first on your devices though. I forget the specs but it is limited.

Oh and I forgot to add that it is way too large of capacity to be allowed on an airplane.

20v 3amp an 12v 2.5amp....appears  to be plenty watts for the draw on my equipment...even enough for my pie in the sky recorder HS-P82 at 18 watts  >:D if ever I get one

Thanks!

Purchased a K2 to take to Lockn. My second Battery Geek 10-14-115 is still going strong....but a drop from the coffee table has effected the meter an it no longer lights up...For now the Battery Geek will power the DR680...if the Battery Geek dies the light on the display goes out to indicate internal battery power.

The K2 will do Festival duty and power my Portico 5012 (and its 12 watt draw) for indoor shows...it's a hoss...not small or light.

Observations:
Power switch. Just a bump turns it and the meters on (very bright meters). I was concerned about this turning off as easy but you must hold for 10 seconds to shut down. If there is no power draw for 30minutes the battery shuts itself down . I've killed a Tekkeon by forgetting to turn it off and leaving it in a zipped up bag till I got back to it a day or two later  :( so I approve of this feature.

Power Outlet. This uses Size M, 5.50mm OD × 2.10mm ID connectors for both the 12v and 20v outlet. I've gaff taped over the 20v outlet so as not to fry my DR680. The cool thing it that it is the same size as my old Battery Geek so all my cables are compatible. Nice to not have to purchase all my power cables again.

Case. Very nice not cheap looking, holes are a snug fit in power outlet to cables.

Is there a Power Distribution Box that takes 20v and provides Multiple outputs at 12v-9v?

I know H₂O at one time built them, but, no more.

Found this one...but only two variable voltage outputs...

https://www.bhphotovideo.com/c/product/1041774-REG/atlas_sound_tsd_dcpdv_variable_dc_power.html

Specs look ok but:
 - it looks like the variable out is for both outputs (in other words the setting affects both outs - both will always be the same voltage)
 - it requires 24v input to operate
 - all connections are screw down terminals which would not be very reliable in the field.

Ran the K2>Tascam DR680 for four days at Lockn'...input was from Aerco MP-2 two channels line in (no phantom power or mic preamp ran on 680). At some point on Sunday afternoon the meter went down to one light. There was a one hour break before Phish...so as not to tempt fate I swapped it out for my old BG 10-14-115 but suspect I would have been fine.

Observations...I managed to kill a fresh set of AA's in the DR680 sometime between checking/packing Wednesday and setup on Thursday.  :banging head:
It prevented the DR680 from starting up with the K2 hooked up...a couple of minutes of panic until I realized the issued & dumped the AA's...not optimal with this unit but at least I was up and running. That night when I shutdown I swear the unit shut down as soon as I stopped recording. DR680 meters are back lit when on external power and I had not hit the power switch and the meters went dark...

$10 of AA's at the festival general store and this didn't happen any more...also I have not been able to reproduce this behavior at the house.

After DR680 shutdown the meters on the K2 go dark immediately, if you hit the power button again on the DR680 it powers right up to external power and the K2 Meters light up also. But, after shutdown I think the K2 stays on more like 30 Seconds instead of 30 minutes. More than 30 Seconds you must hit the power button on and restart the K2.

Hitting the power button while there is a draw on the K2 does nothing...that is comforting.

The K2 Really does require 4hrs or more to charge...

Overall I'm very happy with how it provided Festival Power. It is a Heavy Beast though...Would love to find a compact way to step down 20v 3amp to multiple 2 -12v and 7.2v (Grace V2) outputs. That way I could get a F8 and run the Aerco and Grace Pre's off one large battery.
