Does this run on just battery life? or is the USB needed to run the aquarium?

The 3 "AA" batteries are for the calendar/clock and source of the fish tank and lamp is the USB/DC5.0V.

The clock and sounds run by battery. The filter and colored light/led lights run via the USB

batteries are needed for the clock, but the aquarium runs on ubs, the motor and the light for the aquarium runs by usb. i hope this helps

It does not run on batteries it gets it's power from the docking station that it is plugged in to.

It should be fine. I use my timer for my aquarium lights. You can turn the thing that is plugged in on and off 6 times in 1 day if I remember correctly. So far I've had no problems with the timer and I find it really easy to use.

I use a single battery for this and all of my acc (fish finder, pumps, lights and such). I have no issues being out 4-6hrs at a time.

Hello Marbe,The unit runs on standard USB output. It does not use batteries and has no replaceable parts. It utilizes LEDs for lifetime operation, and offers a lifetime warranty to the original purchaser. The standard unit comes with USB cable and operates from any device which has a USB port. There are two accessories, one is a converter for mains supply and the other is for car adapter (cigarette lighter).

Battery life was great. I took pictures snorkeling for probably 3 hours and then rest of the day without the battery dying. Came with wall plug for USB cord.

don't really know. I have an average size battery, fish for 2-3 hours, have never run down the battery.

No need power supply becaues it works off of the water pressure itself, so there is no electricity needed to run it. I used with my RO.

No, it doesn't run on battery. It gets its power from your PC when you plug in the USB connection.

I guess it all depends on the battery and how often the pump will turn on. Get a GOOD Deep cycle marine battery and it will go for hours. I got it for peace of mind just in case the power goes out. Hasn't run yet, but neither did my AC sump.

No batteries are needed. It gets what little power it needs from the USB port

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.

not a lot, I have one running 24/7. I have it on a pretty basic power strip. No issues so far, and my entire fish tank (air pumps, lights and filters) use very little energy.

This device is IPX7 waterproof rated, meaning 1m of depth for 30 minutes. As for USB, it can be powered off of USB, but not charged.

Hi Steven -- I run it on a single USB alone, but it also comes with a second USB cable/jack for extra power. I haven't needed it. Overall happy so far.

I don't think it needs to be a "high" current usb. I have been running it about 12 hours a day on a regular usb adapter. It does have a battery, which I didn't expect, and really like as you can disconnect it from the adapter and it will give you a portable light. I really like this little desk-light. I hope this helps!

The water pic runs on a battery that is charged by the supplied transformer. The input voltage of the transformer is 110v. I find that the fully charged battery will run for about 3 weeks if used once a day. Twice a day will last for about 10 days. Hope this answers your question. Sincerely, Harry Freedman.
