    • I'm really glad I added this to my pump
I started out first with just just the 12W pump. I am using it in a bird bath. The pump and solar panel work great- but only when fairly bright sunlight is directly hitting the panel. I guess that should be an obvious limitation of something that is solar, but I still found it a little surprising that it needed such strong light. I then decided to try this battery. My only expectation was that it would keep them pump going when clouds where passing over, or there were brief periods of shade. It did all that- and a lot more. The pump now stars running much earlier in the morning, before it is even getting much direct sun and then it just runs pretty steadily, even on cloudy days. In general- it's just made the pump a whole lot better. I cannot speak to its longevity, because I've only had it a few weeks, but it looks well made. Hopefully it will last. I'm very glad I bought it and would recommend to anyone with this pump. ... show more

    • Charges great and last many hours after sun set.
For those that say the solar panel has no out put if a cloud passes by this is the solution to maintain the pump. so far the panel battery and pump have pumped 20,000 gallons. I used this to pump ou a swimming pool. LOL

    • Great for Nighttime Use, But Sacrifices Power
Setup was easy peasy. Instructions were clear, and the battery came pre-charged, so I was able to use it right away. There’s no indicator for battery level though, so I honestly have no idea how long it takes to fully charge via solar. The only way I know it’s out of power? When the fountain just stops. LOL. I don’t know the exact runtime, but one night we came home around 12:30 AM and the fountain was still going. The flow wasn’t strong, but it was steady like a pee, LOL. My setup uses a PVC pipe to create that effect—no splash, no arc, just a calm, continuous stream. It really adds a peaceful vibe to the garden, like a tiny spring in the background. By 5 AM it’s usually off, so the battery seems to last until sometime between midnight and early morning. That said, it’s nice to hear the water at night when we’re relaxing in the pergola. It gives the space a calm, soothing feel. Here’s the trade-off: without the battery, the fountain is stronger—like noticeably stronger. As soon as the sun hits the panel, the water pressure is great. But it shuts off as soon as the sun sets behind my neighbors tree. With the battery plugged in, it lasts longer into the night, but the flow is weaker—even during the day. I think the panel splits its power between charging the battery and running the pump, so you lose a bit of performance. I added the ECO-WORTHY 16.4 ft extension cord. Game-changer. It lets me mount the solar panel higher up where the sun hits it better, but I can still access the connector easily down below. That’s where I plug in the battery when I want extra hours of runtime. Honestly, if you’re picking between the battery or the extension cord, get the cord first. Better sun placement really helps performance. My routine now? I charge the battery with the wall plug and only use it when we plan to hang out in the garden after sunset. That way, we enjoy full power during the day and keep the vibe going into the evening. So is it worth it? If you want strong water flow during the day and we'll only be hanging out the garden during daytime, skip the battery. If you want longer runtime into the night, buy the battery. Want both? Do what I do—charge the battery separately and plug it in only when needed. Long-term durability? We’ll see. For now, it works for what I need. Also check my video and you'll the fountain runs noticeably stronger when the battery isn’t connected. ... show more

    • Worked most of the summer
The battery has worked most of the summer but now it won't turn on the pump once the sun comes back in the morning. I have to unplug and replug the pump from the battery to get the pump to start up again. That's really annoying. The solar panel directly connected works. the sun is shining and the battery is getting charged but it won't send current to the pump until it's reconnected. ... show more

    • Regulates flow and keeps it working when the sun goes away
Without the battery, the pump power fluctuates with the sunlight. At maximum, the flow from the pump was very strong. Almost too strong. With this battery, the flow remains constant, and not excessive. Huge improvement.

    • Nice battery
Easy to use and holds power well. The solar plane it attaches to could be better but the battery is very functional.

    • not good if you rely on solar to recharge
LAST UPDATE: Back to 2 stars. 2000 cycle life is misleading if not outright lying. Used for 3 months last year and it started up this spring only to be nonfunctional after a few weeks. Unfortunately, I purchased another setup before realizing it would require a new battery every year. I suppose solar battery technology isn't where it needs to be for a reasonable price. Just wish they would be honest about functionality. This is no fluke based on other reviews. UPDATE: from 2 to 4 stars. Even though I fully charged it by outlet, it only ran without direct sunlight the first night and then did nothing for the next 2. However, after the third day it started charging by sunlight alone. It now runs for several hours without the sun. I think it does what it's designed to do and the power is fine for my purposes. The missing star is because there is no available lighting element for it and the battery doesn't have any features to adjust. Plug and play but it just runs till it runs out. I have a cheap one with lights that conserves energy for dusk to set in before it restarts. I guess that's not the audience they are targeting. For your purposes it may work well. I bought a case for it since they say it shouldn't get wet. Would be nice if came with better protection since it's meant to be outside. All in all I'd consider it again if I'm looking for something just for consistent daytime flow. It does that well. Considering that it took half a day to charge in an outlet, there is no way the panel will be effective in recharging while also running the pump. The capacity of the battery is fine as it will run the pump for hours when fully charged. The issue is that the panel doesn't charge it at all so after the first night, you either plug it back in an outlet or have a dead battery. I won't get another eco-worthy pump since there is no way to run it without direct sunlight. The search continues for an affordable solar solution. ... show more
