Review: Saved Me the Cost of Two New Batteries – Absolutely Brilliant Charger! - I bought the NOCO GENIUS10 10A Smart Battery Charger for my Volkswagen T6.1 camper van, after being told both my batteries were finished and needed replacing. I decided to give this charger a try before spending hundreds on new ones — and I’m so glad I did! Within a couple of days, it completely reconditioned and revived both batteries, bringing them back to full health. They now hold charge perfectly and start the van effortlessly every time. This unit genuinely paid for itself the moment it restored those batteries. The reconditioning mode is fantastic, and the built-in temperature compensation ensures safe and efficient charging regardless of the weather. It automatically adjusts the charging profile, which is ideal for a camper van parked outside in varying conditions. The GENIUS10 feels well-built and very user-friendly. The indicator lights clearly show the charging stage, and setup is as simple as connecting the clamps and pressing a button. It works with both lead-acid and lithium batteries, giving great flexibility if you ever upgrade or use leisure batteries. I also appreciate that it’s a true set‑and‑forget smart charger — no risk of overcharging or damage, which makes long-term maintenance effortless. After seeing what it’s capable of, I’d recommend the NOCO GENIUS10 to anyone with a car, van, or camper that’s prone to battery drain. It’s one of those rare tools that actually delivers beyond expectations and saves serious money. A must‑have for any vehicle owner!
Review: Useful tool for any garage - Really simple to use with multiple options for charging different battery types. Good size, really good weight and quaility to it which helps justify the price. Charges batteries well, useful tool for any garage.

## Questions & Answers

**Q: I have a 200 ah battery hooked up to solar via an inverter. can i use this when sun isn’t shining? do i need to disconnect from the inverter?**
A: Hi
 I’ve had mine a few months and it’s very good. I use it to keep two separate banks of two x 120ah batteries topped up when my solar isn’t enough. I plug it into the 240 electric and fasten it onto my inverter. My batteries were often going flat, they are always full now. This item also has the ability to bring dead batteries back to life it is an amazing product. There are also loads of accessories available to buy so that you can use it for other things. It charged my car battery up beautifully yesterday. I wish I’d had this years ago it’s well worth the money

**Q: Will supply mode supply constant 10a with the battery connected? need it for flashing ecu**
A: It depends if tuning the ECU requires applying a "load" (e.g., turning on lights) during reprogramming. If yes, then it's not sufficient. If no, then using the 12V Supply Mode should work, but remember not to add any loads during the process. It is also best practice to contact the manufacturer to make sure the vehicle does not draw more than 10-amps during reprogramming.

**Q: Can I charge my iphone**
A: For phones and other USB charged devices buy the NOCO Boost Sport or similar unit which is a combined 12v jump starter, USB supply/charger and 5 mode LED emergency torch designed to be kept in the vehicle.

For camping/day trips it can be recharged with a small solar panel or from a vehicle socket as it has standard USB input and outputs.

**Q: Live in a flat so my car is always parked in street or in a public car park so can't plug in to mains/connect to battery in car at same time. Suitable**
A: You can remove the battery and charge it in your flat
