Thanks for the great review! $22 is cheap insurance. 

I wish I could find a pack like this that also charged via solar for my pond.

Great idea! I am SO going to find something solar that works for the 17g daphnia tub I'm hoping to set up in the next few days...

Does it power two usbs?

Sort of. The port that you use to charge it can also be used as a second output port, so it can work on two devices if it's not plugged into the wall. Which cancels out the "pass through" benefit.

This was such a good idea! This is definitely going on my list of upgrades ideas for when I start my fishroom build. I’d love to see how many tanks it could power if the usb went to a gang valve. For my main fishroom build I was going to go with a linear piston air pump to run the room but I think I’d do this with one usb air pump and run lines to a few tanks that I’d be most worried about.

Not sure how powerful the USB nano pump will be on a gang valve...I wouldn't trust it for more than two tanks in an emergency. Might consider a UPS for the linear piston pump instead and keep your whole fish room running.

(UPS test coming soon. I did one of those too!)

Thank you so much for the detailed review! After our last stretch of multi-day power outages, I started researching batteries and it got a little overwhelming for me. Good work!

I’m still new to the hobby, what’s a UPS @Bill Smith

Uninterruptible Power Supply. Basically a power strip with a giant battery on it. It's intended for desktop computers, to give you a few minutes to save your work in the event of a power failure. But those draw a lot more watts than a simple aquarium filter pump, so it should be even better for those, right?

So I ran a test with an entry level UPS to see how much time I could get. I'll post those results in a new thread in a couple more days.

Spoiler: You'll get maybe a couple hours; not worth it. 

Just run backup sponge filters in your pond, spare tank, breeder tank, quarantine tank, etc. and one of the above battery packs and you're golden for days!

If I had a fish room, I'd seriously consider running a small pond full of sponge filters and overloaded with cleanup crew (siamese algae eaters, bristlenose plecos, snails, etc.). And just place them whenever you need an extra boost somewhere.

This thread is a great example of what I hope to accomplish with this forum. This will serve as an information source for many forum goers to come. This is what I was able to test for myself when bringing the product to market, but never got the time to do a write up, or video etc. Plus I like to see that our new upgraded usb adapter is powering. In my previous tests I used a build in charger/adapter to accomplish this but you get twice as much run time as my setup was. Nice work!

Thank you Cory for the kind words, it means a lot. Not to derail this thread or anything, but thank you for setting up this forum. I don't make videos, and I have no interest in setting up a channel. So this forum provides a way for me to share what I've learned in a format I'm more comfortable with.

More to come in the coming weeks, I hope!

Thanks for reading!

Bill

This should be an inspiration to others as far as detail and information goes! Once, I get my new place and tanks setup I hope to write about it as I plan to run all my tanks with solar power.

Thanks. that is what i was looking for. I bought 5 one for each of my tanks. My theory is that one airstone can provide enough air in a power outage where i normally run two in each tank. Part of my hurricane preparedness.

Your article reads like an engineer wrote it (with some writing skills), as a retired electrical engineer i give this a 👍.

By the way, I tried a couple different solar powered battery banks and never had one that worked well enough with our norwest sun exposure. I am hopeful that someone can find one that'll run a remote pond as I think it's doable.

Thanks Cory, that's exactly the one I had ordered and arrived yesterday! At $27, with high mAh and multiple panels, it's worth a test or two, and I can use it for camping if it doesn't power a USB nano pump indefinitely.

I'm Southern California and I get lots of exposure, and the time of the year is right...will be interesting to see. Maybe a hybrid approach of manually charging on semi-regular basis, and using the solar to drastically slow down the power drain?

We'll see...I'll be posting initial results in a couple weeks, but it sounds like a year-long test to do it properly, unless it's a fail at the outset.

Thanks!

I quickly made a small device for emergency/portable use for my USB nano air-pump.

Had spare parts laying around and did some soldering.  Can use 4 high capacity rechargeable size AA 2800 mah NiMh batteries, for the necessary input voltage required by the pump.  

Works great and now made multiple units, one for each aquarium.  Just plugs in and it didn't cost me anything to build.

Ah, very cool. I didn't know you could just hook up a USB port to a battery pack like that. I have both...gotta try it. How do you know which wires to hook up? And I wonder if you could increase the pumping power by boosting the voltage?

Hi Bill,

Nice to meet you....  I used a USB 2.0 mating connector and viewed the pin diagram on the internet for observing the proper wires to use.  Also, proper direct current (dc) voltage polarity must be observed.  There are 2 data lines (which will not be used) & 2 power lines which were used.  Do a search on the connector and you will see what I mean.

BTW, the pump, I would imagine is only rated for 5 volts, USB voltages and I definitely would NOT use higher input voltages.  What might help is having  higher current capable batteries, for longer run times, etc.  

With the above mentioned batteries fully charged, I can operate the pump for about 12 hours minimum.

Of course, the above information is provided "as-is" and any personal experimentation is at your own risk.

I will bring this question to the sailing forum I am on, as many folks are using solar for refrigeration, charging, and other functions, while balancing cost, weight, space, and efficiency.

Can you specify power requirements for me to ask the right questions?

Streewise, What is the total wattage consumption that is needed?  I feel that to be looking for a device such as this, one would need to know their power requirements, first.

I saw this post and thought... “I gotta get one of those.” Finally ordered because when the hurricane rolled through and power was out about 24 hours, I thought we would be fine. I have a back I could plug in if needed. Lost at least 3 shrimp...not a big deal but realize you never know.

I need to pick up some of these now.  NOAA issued a “La Niña Watch” earlier this summer and apparently we're still looking at around a 50 percent chance that it's going to be a La Niña fall and winter.  Since I live in a north Seattle suburb that is prone to power outages due to the number of trees (We live in Lake Forest Park but were warned that it's nickname is Lake Forest Dark) we see at least a few power outages a year.  The worst one lasted for days.

You could even go for a big UPS for more time and a bigger battery. Just don’t turn off a UPS when the power is out. We had a massive storm outage here and I brought my UPS to help my local restaurant close out tabs. I had to stop in at the local FD with a generator to power it up again before delivering it to the the restaurant to use on battery power.

My fishroom is on a UPS that will run the room for about 24 - 48 hours if we lose power.

I have also got a generator if the outage looks extended

I have done some calculations and if the earth is hit by a civilization ending solar flare, these 2 APC UPS's will run my fishroom until such time as civilization is rebuilt (as long as all that I am powering are USB Nano Pumps running airstones).

Extending the USB Nano Pump: A Test of Power

As my order history will attest, the USB Nano Pump is hands-down my favorite Aquarium Co-Op product. It's crazy quiet and powerful for the money. In my home office where I have five tanks, there is ZERO humming sound coming from the five nano pumps providing air to the 20 longs on a wall rack. All I hear is the air rushing "white noise" that even serves to mask the hums of my hang-on-back filters. Find me a conventional 4-port pump that can accomplish that! This gives me a room with several tanks that aren't singing in the key of "E"!
 
But testimonial aside, I recalled Cory talking about the benefits of the "USB" aspect of the pump; especially that it can be powered by a backup battery during power failures. But what if that could be taken a step further? What if it could be used as a daily workhorse pump THAT ALSO automatically switches over to backup power when the power does go out? How long will it last? Can it do this without human intervention?
 
For twenty bucks and ZERO DIY skills, you bet it can!
 
SELECTING THE BACKUP BATTERY
 
In making my choice of backup battery, I listed the following criteria that needed to be satisfied:
 
1. It has to be Compact
2. It has to Last a Long time
3. It has to Power my pump on wall power
4. It has to Switch to battery power without my touching it
5. It has to be Affordable; I have a lot of pumps!
 
With that in mind and a lot of research, I settled on this UGREEN Portable charger for phones and tablets, for $22 on Amazon.
 
image.png
 
(I'm receiving and want no affiliate kickbacks for this.)
 
 
It mostly matched up with my requirements:
 
1. Compact: It's about the size of a pack of cigarettes
2. Long-Lasting: 10,000mAh will be tested 
3. Power: Pass-through feature sends wall-power directly to the pump
4. Switch: Pass-through charges the battery and switches over when unplugged
5. Affordable: Mixed feelings on this...pass-through isn't cheap!
6. Bonus! Digital readout shows the percentage of charge remaining
 
 
What is pass-through power technology?
 
You can't just plug the pump into any phone charger and expect it to power the pump while the charger is plugged into your wall; most phone chargers will stop powering your device when they are being charged themselves. But with "pass-through", the charger passes your wall power through to your charging device while it charges itself. Instant permanent battery backup!
 
How to use it?
 
Simply plug the battery backup between the USB pump and its USB charging adapter that comes with it. You need nothing else!
 
image.png
 
So let's dive into the testing...
 
TEST ONE: DOES IT WORK WITH NON-PHONE DEVICES?
 
What we're proposing here is to plug in a device that doesn't draw power the same way as a phone does, into a powering device that's made for phones and tablets. Will it handle low voltage fish stuff?
 
This article wouldn't exist if the answer weren't a resounding Yes!
 
I connected it all and plugged it into the wall. It immediately started the pump and started charging itself at the same time. When I unplugged the power from the wall, the pump kept going and the battery started draining. SLOWLY.
 
Blue or orange port?
 
I tested the charging process twice, curious about whether choosing the blue or orange ports on the new Aquarium Co-Op charger plug that came with the pump would make a difference in charging time. It made no difference.
 
So this will work. But for how long? Here's where it gets interesting.
 
TEST TWO: HOW LONG DOES IT LAST?
 
I charged it up to 100% while connected to the pump (about 3-4 hours), and then unplugged everything from the wall to simulate a power failure.
 
The pump continued to run for 60 HOURS. That's two and a half days!
 
image.png
 
Not much more to be said there. It's quite an effective backup power source!
 
TEST THREE: OKAY, BUT HOW LONG DOES IT REALLY LAST?
 
On the theory that it will not last as long when it's under a load and actually powering a real airstone in water pressure, I connected it to a never-clog airstone on 24" of airline tubing that had already been running for several months in 12" of water depth.
 
image.png
 
The runtime result was another round number: 50 HOURS on a full charge.
 
 
So this means that the pump was powered for about 17% less time while under a basic load. Logically, I'd assume that as the airstone becomes more clogged, its capacity for backup time will be diminished even more.
 
Mounting?
 
The battery pack is not terribly heavy, so it can be mounted with some double-sided foam tape to the back or side of the aquarium, or any other flat surface so that it doesn't dangle.
 
image.png
 
CONCLUSION
 
The combination of 2+ days' power, always-ready pass-through powering, and the compact size makes this a huge winner.
 
I'm buying one of these for every one of my USB Nano Pumps. Yes, $22 can add up fast, but for me, it's a small price to pay for the peace of mind. When the power goes out, I will have oxygenated water for days! Even if I were to lose most of the beneficial bacteria, the bacteria that remains in proximity to the moving water caused by the bubbles (on the glass, rocks, gravel, and decorations) will serve as a seed population for a new colony. But that's a moot point if the pump is powering a sponge filter!
 
What more is there to say? Spread the word: USB battery backups aren't just for phones!

Thank you @bill smith I bought three of them for 3 tanks and they work amazing.

Well, actually it wouldn't be too much of a tutorial anyway, lol.  I just had some extra parts laying around like the female USB 2.0 connector and 4 AA battery holder.  I researched the female pin-out USB 2.0 connector and just properly soldered it up for use.  

(Positive+) USB pin to (positive+) battery holder wire/terminal.  (Negative -) USB pin to (negative -) battery holder wire/terminal.

 

IMG_0901.JPG.6b06520663cc6fd974e6ff14857e78ad.JPG

 

Proper direct current (dc) voltage polarity must be observed.  There are 2 data lines (which are in the middle and will not be used) & 2 power lines which were obviously used.  A voltage power line is on each side of the connector.

Am not sure if you have extra parts or have electronic & soldering skills, since the pins are very delicate, etc.  Anyway, similar units already come preassembled for just few dollars and are easily available online, etc.  

The picture above is for reference only & the actual soldering is done, of course, on the back side of the connector.  One would have to follow the pin to the back for soldering, etc.  

There are available rechargeable battery banks with USB ports as well.  

What I  most like about my design though is that you can swap out the rechargeable batteries, when they fail.  Unlike a factory made battery bank, once their installed battery fails, it is a throw away item, in most cases.

Great write-up, thanks!  I have a similar small battery power source, but I noticed the other day that my emergency car battery jumper thing has a USB port.  Tried it out, works fine, I have no idea of the duration.

Specs on the reserve capacity of that model seems to say 9Ah, or 9,000 mAh, which is very close to my test model. So you should get close to two days as well, I would think.
