Naztech PB15000 -- My New Favorite Universal Battery
« on: May 13, 2012, 10:35:51 AM »
I just bought one of these last week.  Found it at an airport 'gadget' shop here in Pittsburgh.

http://www.naztech.com/naztech-cat-power-banks/285-naztech-product-bp15000-universal-power-bank.html

It's pricey at $149, but the super high capacity, all metal case, and the digital display that reads out in voltage made it a buy decision for me.  So far, I'm very happy with this decision.  The only negative thing I can say so far is, why no 6V setting?

I'm up to 48 hours continuous run-time and have two of four bars still lit.  Tascam DR2D running with the backlight on, internal mics, high gain...using tips that are included in the battery package and the 5V power jack on the Tascam and the USB port on the battery.  I think I'm pretty safe suspending this run-time test and concluding that this will safely run my recorder all weekend for a festival.  :)

Hmm, better $/Wh than a tekkeon 3450i ($3.40 vs $2.70), but slightly less capacity. Nice deal overall.

Whats the ma draw on the tascam? The naztech specs say it has a max out of 200ma on the usb ports. It would make a great sonosax sx-m2 battery with that 21v setting. A regulated supply, but still.

It's pricey at $149, but the super high capacity, all metal case, and the digital display that reads out in voltage made it a buy decision for me.  So far, I'm very happy with this decision.  The only negative thing I can say so far is, why no 6V setting?

The metal case does look nice (its one thing I don't like about the tekkeon series), what's the actual length on it? I'm guessing 130mm and not just 13.

Also, other than taping gear, what consumer gear uses 6V anymore? My phone, mp3 player (which is ancient), wife's phone, etc all use usb power. Honest question, I don't know.

Low output on the USB buss, only 200mA?

Page made the same observation.  That actually got by me before now. 

Hmmm...well I`ll give this a try with my DR100mkii and see if there are any issues because the dr100 definitely pulls more than 200ma. 

Actually I was thinking that the dr2d pulled between 300 and 400 because people have reported getting 6 to 7 hours on a pair of alkalines which I think are around 2800mah.

2800 mah / 7h = 400ma or so.

Fwiw, during the 48 hour test of runtime that I did the battery powered the dr2d fine and the was never any heat issues.

13x21x170 roughly equals 1/2x13/16x7 inches; the pdf spec sheet shows 113x21x175 (4.5x0.82x7.0)which is much more inline with the pictures.

A nice find other than the non500mA USB output but not nice enough for me to ditch the Tekkeon or BatteryGeek 10-14-88 though when one of them dies I'll consider this (or whatever it's updated with when the time comes).

I've tried running my USBPre2 on less than 500 mA and some mics would not work because phantom power was not up to spec.  the preamp seemed to operate ok otherwise...I forget what it specs out at, but my high draw mics were no good.

Yes, the second size is correct.  This is roughly the same size as a DVD battery, maybe just a tiny bigger.

Page, as far as the 6v setting, I don't know what else might run off of 6v.  In audio gear, I've owned a number of pre/adc's that run from 6v; V3, PSP-2, PSP-3, Mini-me, Mini-MP.  However, if there's not much that operates from 6v anymore, that would probably explain why they didn't include that as one of the settings.  Currently, my preamp, ADC, and mic power supply all operate from variable voltage, but 6v is the lower end of the range in all cases, so 6v would be nice if only to max out the run-time I could get with this battery.

OK, good feedback thanks Kirk.  Did the mics work, but just underpowered/distorted or will they just not work at all?  If the answer is that they worked, was it obvious that they were not powered sufficiently by monitoring say your TV or did you have to take your mics out to the venue under high SPL's to determine if there was enough power?  Just trying to figure out what I need to do to make sure everything is either OK, or not.

I totally agree, I've seen lots of portable pro/prosumer audio gear allow 6v, but almost nothing on the consumer end. My D50 takes 6v, but again, it's not a consumer device and I think thats what they are targeting.

no my mics would not power up.  It was too much draw between the mics and the unit, I cannot remember exactly what the rating was I just know it was under 500mA.  These are mics that require 10mA @ 48volts phantom power.

What say you folks about this one? $37.70 SHIPPED - the downside is you will need a Laptop power supply that is compatible to charge it...I don't see a walwart with this unit.

61WH 16v-19v (I know that don't help many of us) & USB output

I've almost pulled the trigger to use it just to power my Denecke PS2 for LDC and AMP HUNGRY Avenson STO-2 Omni at festivials...I'm afraid to take those two on the road to a festie as they suck down my old Tekkeon MP3300 half way in a couple of hours...the PS2 says it will accept 6.8 – 18 volts on input

I guess you could use it to recharge your Tekkeon too?

I can't address your comment about charging, however you say that your PS2 goes from 6.8 - 18V.  That means that with this battery you'd only be able to use it at the 16V setting, which wouldn't give you a very long run-time.  If the battery allowed you to run the PS2 with a lower voltage, you could get better run-times.  I'm not sure if you're averse to buying from Hong Kong, but this is the battery I will be buying next and I would think would be a better option to the one you've listed, although again it's from a China supplier instead of US based.  I search the term '5v 9v 12v' on ebay and this battery hits 300 times, so you might be able to find one in the US.  My only concern about this battery is the on/off switch...I'd prefer it without that switch but just like the battery you link to, you can't beat the price/capacity ratio of this battery.

I have one of those batteries. I cut down some rubber feet and put them next to the switch as a guard.  It is very easy to hit off with the switch.  Some  other down sides are no meter of any kind on those batteries, and fairly long charge times.

Just wondering if you had the chance to try it out on the DR100mkii yet?  I have the same recorder and have been looking for a solid remote power source.  This battery sounds great, but I'd like know that it will work well before I buy.

I wish I knew why the specs say that it's limited to 200ma because I'm having no problems whatsoever using the 5V USB connection on everything...including powering mics with phantom through the DR100MKii.  So, the answer to your question is yes, I did try this and it works like a champ.

But this thread is about the Naztech battery not the Sony M10...and your configuration was not powering any mics.

That looks like a good battery. kirkd, you say you have one? ...and it works reliably? Do you have a volt ohm meter? I'd like to know what voltage you really get on the 12v setting.

I've been carrying 12v lead after I started having problems with a DVD battery powering my DR-680.
DR-680 users could use that thing if it's reliable and clean.

Chuck,
I can't say I'd recommend it.  It has two big flaws.  1. You can easily hit the on/off switch on the battery and losing power during recod with a 680 very bad.  2. No metering of anykind so you have no idea how much battery there is still to use.   The one other draw back is a long charging time.    I bought it for 5V use.  I have used it as a first set battery but without meters I am not willing to run it long.  ANd I don't have time or patience to test it out.  Especially since I have 6 DVD batteries.

I recommend buying a universal charger.  There's some learning curve associated, but not much really.  Once you get one of these a) you'll never need another battery charger, and b) you have control over charging so you can recharge your batteries as fast or slow as you want.  Again, some education required but nothing complicated at all.

I agree with the on-off switch being a PITA, but I've never let the lack of a meter influence my battery choice.  It's not difficult to get around simply by either doing run-time tests on your equipment or figuring out run-times knowing the battery capacity and doing the math based on the current draw of your device.

Hope this helps.

I really question whether that "200mA (MAX)" figure is accurate.  Maybe it's a typo or something, I dunno, it just doesn't seem right.

I'm thinking about getting one of their other batteries - the PB10800 (http://www.jr.com/naztech/pe/NAZ_PB10800/).  It only does 5V, but there are 5 usb jacks and it's  rated at 2.5A.  (They say you can charge 2 iPads simultaneously with this thing).  I don't know much about battery technology, but it's strange that their higher end, much more expensive battery is rated that much lower on the USB port.   

Anyway, I'm thinking the 10800 could be a real nice solution for powering the USBPre2 and a Tascam DR-100mk2.  (the USBPre2 spec is "400mA max" and the Tascam is "2.0A".  I was in Radio Shack the other day and saw they have a USB connector for their Adapt-a-plug stuff.  Does anyone know what the polarity is on a standard USB connector?  I'm assuming if I put together an adaptaplug cable for the Tascam that it would be standard polarity on both ends (and not the reverse polarity/ tip negative that Roland uses)?

If I'm drawing 2.4A and this thing has 10800mAh, how much runtime could I expect from this setup?  4 hours or so?  That doesn't seem like a lot... is my math way off here?

The USBPre2 power spec is 500mA @ 5volts(+/- 10%) I'm not sure where you got the 400 rating but USB power is 500mA.  I had also asked Nic at Sound Devices about the range when I first started researching power options and building my own voltage regulator.  So the spec I cited is from the techs at sound devices.  The expected draw on an average set of mics with phantom is in the 350-400mAh range.  Some of the mics that require higher current could drive the figure up into the 450 range.   One issue I had when using a self made regulator was there were dips in the current that caused the USBPre2 to lose lock with a Tascam DR-680.  It would happen so fast that you never saw the 680 display a DIN unlock message but it would display DIN lock showing it had aquired lock after losing it.   This also caused visible audio spikes in the spdif stream and just generally fucked up the spdif sync too.  I never bothered to test the actual output of the phantom since it was not working but the lower voltage could cause issues that might not be redily apperant IE: lower phantom voltage and/or current which could reduce the dynamic range of mics or make them sound different than they do with correct phantom supplied.  Since the Spdif stream was causing me issues I just skipped the voltage regulator idea completely.  And opted to buy a battery that supplied the right specs.  There are various ways to test battery output even without complicated equipment.  Just google it and I think you could get a few options and then you could find out with a more substantial answer.   Sound Devices was pretty firm on there answer of what voltages to run the box at.  And since their products usually have a very broad range of operating voltages I personally would risk running the unit outside of that range.  Besides the phantom power and spdif stream issues it could start affecting AD conversions ir headroom or who knows what since there is not a lot of excess voltage to play around with.

{edited to clarify power ranges for usbpre2}

You are right about the USBPre 2 specs being 5v/500mA... it's right there in the manual.  Not sure where I got that 400 mA number (I know I cut and pasted it from somewhere - I thought it was the SD web site).  Anyway thanks for the clarification. 

Am I correct in assuming this: 

If the 2 devices are spec'd at 2500 mA combined draw, but I'm only running phantom on one (the preamp), that the max will not be reached on both and therefore the actual current will be much lower?

2.5 amps is a pretty hefty draw.  and I don't know about "ACTUAL CURRENT WILL BE MUCH LOWER"  The "much" part might not be accurate.  I'd guess you idea is basically right but how right would require testing of some sort.  Running phantom might only increase the draw a little bit or it could increase it a lot, depends on how the thing is designed to work.

Well, I have one of the PB10800 batteries on the way, so we shall see. 

I realize I'm pushing the limits of the 2.5A max on the battery's output, but I'm encouraged by tonedeaf's experience running the MKii w/ phantom on with no problems

Yeah, test it and see what you get.  If it doesn't work out for you and you have no other uses for it, let me know and if I can find some extra cash laying around I'd consider buying it from you.  I used the PB15000 battery again at Electric Forest Festival and I can't say anything bad about my experience with it.

Thanks for the offer!  If it doesn't work out for taping, I may just keep it to charge phones and ipads for camping or whatever.  But I have a feeling it will be just fine for running the Pre2 and Tascam. 

I just got this thing today... seems pretty solid and it's actually smaller than I thought.  About the same weight and thickness as a DVD battery, and about 1/2 inch smaller in depth and maybe 3/4 smaller in width.  (I'll try to take some pictures later).

A couple observations:

- The power button is recessed AND you have to hold it for at least a second to turn it off, so it would be virtually impossible to turn it off by mistake... nice feature!

- It comes with a tip for the Tascam and/or the JB3, so no need to make a cable or buy an adaptaplug setup

The 5 USB ports are labeled as follows:

1: 5V/1.3A Universal
2: 5V/2.1A iPad/tablets
3: 5V/1A Universal
4: 5V/1A Universal
5: 5V/0.5A Universal

So, theoretically Port 2 will be fine for the Tascam, and the USB-Pre2 could run on any of the others (but I would run it on 1,3, or 4 just to be safe). 

Hopefully I'll have a chance to hook some mics up and run some tests in the next couple days.

I ran the Naztech PB10800 yesterday for almost 6 hours, powering the USBPre-2 and Tascam DR-100mkII.   (Exact setup was  AKG 460s/CK8s > USBPre-2 > Tascam.  SPDIF in to Tascam, recording at 44.1/24-bit.  Everything worked flawlessly, no heat or any other issues.   

The first light (the "80-100%" one) on the battery turned off after almost exactly 2 hours.  The second (60-80%) went off after 4 hrs.  The 3rd (40-60%) light had yet to turn off when I shut it down. 

So...

Looks like this thing will run for ~10 hours.  It should go all day at a festival, if I unplugged the Tascam and let it run off the internals at some point. 

Seems like a nice solution for anyone who just needs 5v power.

Tonedeaf,

That ebay link is now dead. what type of charger were you talking about?

It's called an Imax B6 charger, so just seach ebay and you should get a zillion hits.  Cost should be between $30 and $40.  I use mine to death and absolutely love it (although a couple of buttons have fallen off of mine, but I get around that easy enough). 

Like I said before, the manual is a little rough.  There's a small learning curve involved since basically what you're doing is taking all chargers and putting them into one. 

I can help you out if you decide to buy this charger and can't figure out how to use it, but you basically just use the left button to select the battery chemistry (Lipo, NiMH, pb, etc) and the other buttons to toggle through menu selections, which enable you to set the charge amperage and, in some cases, the charge voltage.  It's not completely random...the menu has presets based on specific battery chemistry, but you do need to know some what you're doing because it's possible to re-charge a battery too quickly and cause damage due to overheating if you choose too large of an amp setting for the specific size battery...read on because I address a couple of simple precautions on ways to prevent this later in this post.   

Anyway, the basic concept of the charger is that you first choose a chemistry.  The charger then has automtic pre-sets for the voltage based on the battery chemsitry.  You then choose the amperage based on the size of the battery.  For some battery chemistries, like lead, you have to know the number of cells in the battery in order to get a correct voltage.  Then amperage can be adjusted based on the desired re-charge time.  It turns out that SLA cells are approximately 2v each, so a 6 volt SLA has 3 cells and a 12v SLA has 6 cells...the number of cells in one of the menu choices when you're setting the charger up for SLA charging.  For any battery chemistry, you set whatever amperage you want (up to 5A) in order to determine how fast you want the batteries to re-charge. 

The four buttons on the charger allow you to step through all of the various menu selections and once you have the charger selected to all of the settings you want, you press and hold the right most button to start recharging.  The charger then tells how far along you are in terms of how many mah have been put into the battery. 

As it's recharging, you can tell charging progress...or how 'full' the battery is...as it's being charged if you know, for example, the capacity of the battery and how far dicharged it was before you put it on the charger.  So, for example, if you have a 3000mah battery that you ran dead the night before, you'll see the charger start slowing down in its charge rate as it approaches the 3000mah point.   If you ran the battery down half way, you'll see the charge rate start to slow down as the meter approaches 1500mah of energy input into the battery.  Also, as the battery gets closer and closer to being fully charged, the amps starts to drop.  It's awesome!

The manual's not totally useless because it does give some amp setting guidelines based on the specific battery chemistry.  I've only had one instance where I was too aggressive with selecting too high of an amp setting, but that was my fault and I was deliberately kinda playing around with the charger to see what degree of control I have with it.  That's when I connected the alligator clip connectors (you get a bunch of different types of connectors inside the box to accomodate a bunch of different battery terminal designs) onto either end of a single NiMH AA battery.  I put the charger on the NiMh setting which set the correct voltage, but I put it on a pretty high amperate (maybe 3 or 4) and it wasn't too long before the charge unit caused that AA to get REALLY hot.  In fact, I caused some of the external packaging to melt.   >:D ;D

I'm not saying this to scare you away from this charger, but just to caution that the amperage setting is everything in terms of how quickly or slowly the battery recharges.  Also, of course the bigger the battery the larger you can set the amperage because there's not as much internal resistance in a big battery.  In the case of that single AA, I was putting way too much current through a single battery.  True, I probably recharged this battery in like 10 minutes or less, but the internal resistance cause me to basically ruin the battery because of the heat was rejected since it wasn't absorbed as energy in the battery.  Battery university says it won't ruin a battery to put it on repeated fast recharge cycle, but it will shorten it's life.

Anyway, it won't take you long using this charger to get a feel for what your settings need to be and like I said, the manual provides guidelines and I can also give you my own guidelines.  However, the bottom line is if you're not sure, then when you put the battery on the charger, feel the battery every so often after starting to recharge.  If it gets too hot then your amp setting is too high.  Take the battery off and lower your amps.

All this said, you can also set the amp setting too low and it will never charge the battery.  A good rule of thumb that I've found for all of the battery chemistries I've used is to start with 1A. 

Oh, one more thing.  FWIW, I have NiMH, Li-ion, Li-Poly, and SLA/lead/pb batteries in my battery arsenal.  Although I tend to still use the stock charger on my wally world and li-poly batteries, I've used this charger on them all.  I generally use this most for my NiMH and lead batteries though. 

Did I mention that I love this thing?
