Solar Power Manager 5v v1.1

I use these to power solar Meshtastic LoRA Nodes. I have a 5v6w solar panel and 3 21700(4500mAh) cells in parallel. Output to the Meshtastic node. It has been up on my tower for 3 weeks and it has kept the batteries fully charged even during sub freezing Temps and multiple days of cloudy conditions. Very happy with the DFRobot controller. I have bought 6 of these now and would buy more.👍

Worked well for what I needed. I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.

Good product, works as advertised. Fully charges the battery from solar, and the reverse indicators are nice to have, just in case. Only con is that if the battery fully dies, the circuit won't restart outputting power to the load. It will recharge the battery, but I have to disconnect and reconnect the load in order to get power to flow again, which is obviously not ideal for applications where the circuit is less accessible. Paired with a large enough battery though, this shouldn't be a concern.

Purchased this on June 5th, 2025 for a solar powered weather station. Little over 3 months later, this is dead. Will not operate even if I plug in 5c USB cable into it. I could understand if this was 2-3 old but 3 months? Update: I am changing my rating as I was sent a replacement. Good customer service.

Needed two different voltage outputs. This thing filled the bill. Using it for a Mota solar note that needs both 3.7 V and 5 V. I think this will do. The trick price is right, showed up fast and would buy again. Compatible with a solar panel.

Just fabulous and worth every penny.

Works very well, I have prime and should be free shipping but shipping cost was added to the product price. For same money can buy on DFrobost at least you don’t have to prime membership.

I bought this to control my 5v solar panel and battery charging for my Meshtastic device. So far this has been excellent at keeping my 10k mAh battery charged. Not only does it do great at charging in low light, the built in safety features are worth it as well.
