Truly and coming from a west Texan *by D***E on January 5, 2025* This thing is amazing. I can't believe there are not more videos about it on youtube. Of course charging an e-bike via a wall charger using mains power will typically be faster, but depending on the capabilities of the solar panel(s) used, it can be very effective. The device does work and it even accommodates several standard voltages used by most e-bikes making the setup quite handy, and it can also be set to custom voltages as well, which does take some patience. I am truly amazed that it works so well, is so small, is so easy to setup, and requires no other device to work(besides a source of power). Provide a source to one end (clearly marked) and connect the battery needing to be charged to the other end(also clearly marked), then set the charging parameters and voila. You can even monitor the progress on the device which shows also shows the charging amps(ultimately determines the total time required to charge). I honestly think that most anyone should not be disappointed with this purchase, so long as they have reasonable expectations and possess a basic understanding of using such electronics. I would also like to add that the seller is responsive, at least, once a purchase has been made. ### ⭐⭐⭐⭐ Manual Hard to follow.... So here it goes *by A***N on May 16, 2024* *** Update after using all summer ***I have not plugged my cart into charger all summer, It's on;y a weekend cart, and has fairly old batteries, But using a 235W panel was enough for my usage...1) Connect solar panel 1st (to non fused wires) It should light up (mine lit up even under Shop lights)2) If your battery voltage IS NOT 48v Hold Button for 10 seconds Green light will go off. Then 1 Click changes voltage.... keep hitting it till your battery voltage is displayed Then Long press button again to store3) NOW Connect to battery. regardless of sticker Connect battery to Fused wires. ## Frequently Bought Together - SUNYIMA MPPT Controller 300W 24V/36V/48V/60V/72V Solar Boost Charge Controller Electric Car Electric Vehicle Charging Voltage Regulator - BougeRV Solar Connectors Y Branch Parallel Adapter Cable Wire Plug Tool Kit for Solar Panel - BougeRV 12 PCS Solar Connectors with Spanners Solar Panel Cable Connectors 6 Pairs Male/Female(10AWG) --- ## 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/505687800-300w-solar-charge-controller](https://www.desertcart.co.uk/products/505687800-300w-solar-charge-controller) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
