There are many small ones which share this design and they're all about the same, although for different prices. These ones are moderately accurate and offer a bit of protection for your battery, but as per the title they're cheap tat and will die quickly, possibly risking your battery. I paid £20 for this and after a month what I have is a wire.. it still conducts but all of the functionality is dead.The USB ports never worked from new. ### ⭐ Don't waste your money *by M***W on Reviewed in the United Kingdom on 11 July 2021* It doesn't stop charging at the set voltage. That means it can eventually boil your battery!It can only match the PV voltage to battery voltage by direct connection, there is no voltage conversion. How do I know? The only inductor inside is a little one for the USB charger. To be fair, it doesn't claim to be MPPT so that's OK.Also the numbers shown on the panel are strange. It is measuring something, but when I compare to multimeter measurements I cannot tell what. It says 5.5 Amps going into the load when no load is connected, but 5.5 Amps were going to the battery. It says 19 Amps are coming off the PV, but that's just wrong.So what's it doing? Eating 14mA all the time, and connecting the panel directly to the battery the way you could with a connector block. Useless.This one sat on my bench too long to get a refund.Edit to add: if you connect the PV when the battery is absent, it may conclude you have a 24V battery (until next power cycle?). The animations on screen suggest it did try to stop charging the battery at the voltage I told it, but it failed to open the circuit. Instead it dropped about 4V across its internals and 4.5A continued to flow. The temperature of the device went up to 53C and it continued to over-charge the battery.There was a funny smell. I disconnected it when the first wisp of smoke came out the top - extra photo shows discolouration of the thermal pad. Maybe I should have left it longer for a more impressive photo? ### ⭐⭐⭐⭐⭐ Good cheap unit works well *by M***Y on Reviewed in the United Kingdom on 22 August 2019* Charges my batteries which is what I wanted. Nice and easy to set up but not entirely sure what all the buttons do and got no idea what the 24h clock is for. No I havent read the instructions nor will I for I am a man. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/122787035-solar-charge-controller-20a-12v-24v-pwm-auto-paremeter-adjustable](https://www.desertcart.co.uk/products/122787035-solar-charge-controller-20a-12v-24v-pwm-auto-paremeter-adjustable) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
