This thing is built to last and endure years of trouble free use and unavoidable incidental elements like water and dust. Small and convenient, set it and forget it; easy as plugging in and connecting the clips. Connect your 5 stage Mini-Pro to your battery, lead/acid, AGM, sealed, gel, you've now done what no other charger in our class does. The Mini-Pro has a desulphation stage that fires very high frequency electrical pulses back through the battery to blow the sulfates off the plates that cause slow charging and poor battery performance, reduced or eliminated sulfates allows a deeper, faster charge, better performance and increases the overall life of the battery significantly. Your battery will now be ready to go when you are no matter how long you leave it. The Mini-Pro XP keeps your battery fully charged with these 5 stages: Desulphation>Bulk Charge>Absorption>Analysis>Float Stage and if your battery voltage drops the Mini-Pro automatically switches to Bulk Charge mode and cycle repeats. No hassles, just leave it plugged in and it safely and indefinitely charges. When you buy you get our 100% Iron Clad, Better than Money Back Guarantee and Our Full 5 Yr. Warranty! If you are not satisfied with your charger (ANY REASON) just call or email and we'll refund or replace your charger. Make sure to get 1 or more before the promotional price is gone forever, don't forget your best friend, it's a great gift too. Perfect for all 12 volt applications: Car , Motorcycle , Boat , Jet Ski. Review: Died today 2/22/2018 - Charger now shows it is charging even when un hooked from battery. Red middle light won't illuminate thus protection is turned off. Now when the clamps touch each other they spark and all lights turn off until clamps are separated. Will check into warranty exchange. KeyLine Chargers KC-125-MPXP 12V 1.25 Amp. So far it has been working well. I let a new battery die below 2 volts for a couple of weeks and have been charging it for about 30 hours now, it's up to 12.99 volts. I did have to jump the battery from a good battery for 20 minutes or so to get this charger to start on it. My charger floats at 13.6 and holds it until unhooked. Desulphation didn't kick on when I first started charging. I had to run my dome lights to bring the battery down to about 11.5 volts and then it desulphated for about 5 seconds. In my opinion this isn't a good desulphator mode, I'd prefer it on all modes. Build is good for what it is. Small plastic housing, not amazing but better than usual wire connections to housing. Long power cable and even longer DC to battery cable which is nice. Gets hot at 133.4F on the top of the charger and 119F on the bottom. The lights like others have commented on are horrible. The company has stated the simple light signals are to keep the cost down, I understand but am not satisfied. Would have much preferred to pay a little more and have a better indicator system. Error signals are clear and easy to understand which is good. Desulphation mode is easy to read, quick flashing green charge light, no middle red, and solid green power. Now this is the crazy part, stages 2,3, & 4 (unless under 12v is detected in 4th stage) are exactly the same flashes so you have no clue what's going on during charging between desulphating and done charging given there are no errors during the charge. Overall I'm OK with this charger given the short time I've had with it. Although if you want the mental security of a good desulphator I may look elsewhere. Also where is this thing made?? I assume overseas but it doesn't say on the charger , box, instructions, or website? It appears the company is based in the USA so I will keep it unless it dies, but will probably be buying another brand as my main charger/maintainer. Will update as needed. Update: 4/9/17 - Charger has been going for 76.5 hours now!! But, the battery is up to 14.25 volts and still charging. Like I said earlier this was about a month old Sam's Club Duracell that was dead below 2 volts for at least 2 weeks. I assume at this point it is in the absorption stage since the temperature of the charger case has dropped from over 133F down to 95.6F. Update: 4/9/17 - Finished charging after 80 hours. Battery ended at 13.46 volts. Will see how it balances out later today. So far very happy, I wouldn't have imagined this battery would take a charge so well. 10 hours after being removed from charger voltage was at 13.16. 4/9/17 - Now I'm trying to restore an old 12v motorcycle battery that has been left to slowly discharge over about 2 years to 2.53 volts with no load. I tried to connect it to a car battery and couldn't keep the voltage above 6 volts, would drain quickly with just the volt meter hooked up. Next I hooked a small 12 volt 400ma transformer to it and have successfully gotten the Keyline to stay in desulfate stage for about 10 minutes. Would be crazy if it restored this battery at all. Will update as needed. Update: 4/11/17 - The charger has been hooked up and desulphating for a couple days on the motorcycle battery. The battery still isn't doing well but is up to 6.3 volts when removed from charger, much better than it was doing but not good. I don't blame this on the charger but the abused battery. Remember it was left dead over 2 years. Will keep it going and updating till I get bored or the charger returns an error. Update: 4/17/17 - Removed charger from motorcycle battery. Just wouldn't get past desulphation, definitely a bad battery. Review: Totally Worth It..... - I bought this charger solely for the purpose of maintaining & extending the service time of my vehicle's battery as I am a DIY person. It is because I am heavily reliant of my only vehicle (2007 Ranger 2wd Diesel) for work, play and emergency purposes. So, downtime for me was never an option. There aren't many chargers that could perform all the 5 functions like this one do at this price point. The value-for-money bargain was almost like a steal it was unbelievable. When it comes to operation, I must say, using this charger was as simple as connecting it to the car battery, let it run its job and the battery was charged and ran with new-like efficiency. I am planning to use this charger recharge the battery once every 20,000 km to keep the battery in a good shape for years to come. All and all, it is an item worthy to be kept in my personal garage and I truly recommend this charger to anyone who did their own auto repair. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00UGDAVKU | | Brand | KeyLine Chargers | | Color | Brown | | Current Rating | 1.25 Amps | | Customer Reviews | 4.0 out of 5 stars 280 Reviews | | Global Trade Identification Number | 00640791978777 | | Input Voltage | 12 Volts | | Item Weight | 0.8 Pounds | | Manufacturer | KeyLine Chargers | | Mfr Part Number | KC-125-MPXP | | Output Voltage | 12 Volts | | Specification Met | certification | | UPC | 640791978777 | ## Images ![KC-125-MPXP 12V 1.25 Amp Automatic Mini Pro-XP Car Battery Charger (5 Stage Maintainer, Conditioner, Desulfator and Tender) - Image 1](https://m.media-amazon.com/images/I/718h84HR0GL.jpg) ![KC-125-MPXP 12V 1.25 Amp Automatic Mini Pro-XP Car Battery Charger (5 Stage Maintainer, Conditioner, Desulfator and Tender) - Image 2](https://m.media-amazon.com/images/I/81ZPbWSI7rL.jpg) ![KC-125-MPXP 12V 1.25 Amp Automatic Mini Pro-XP Car Battery Charger (5 Stage Maintainer, Conditioner, Desulfator and Tender) - Image 3](https://m.media-amazon.com/images/I/81UjQSQzRJL.jpg) ![KC-125-MPXP 12V 1.25 Amp Automatic Mini Pro-XP Car Battery Charger (5 Stage Maintainer, Conditioner, Desulfator and Tender) - Image 4](https://m.media-amazon.com/images/I/712g2u8EOAL.jpg) ![KC-125-MPXP 12V 1.25 Amp Automatic Mini Pro-XP Car Battery Charger (5 Stage Maintainer, Conditioner, Desulfator and Tender) - Image 5](https://m.media-amazon.com/images/I/71YYLA5-dRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Died today 2/22/2018 *by M***L on April 7, 2017* Charger now shows it is charging even when un hooked from battery.

Only used it once.. my review is based purely on a single use. Product works as described. Only time will tell if it will hold up to regular use. UPDATE* - 1/30/2020 Had to contact the manufacturer to start the process of a warranty claim. It was fairly simple. They just required my order number to verify the purchase date. Item quit working after only being used a few times. I actually had a need for it recently only to find out that it no longer work.. checked the fuses and outside of that I did not want to "open" it as that probably would have voided the warranty. I can attest to the fact that they do honor their warranty and for that reason I updated my review in the event you are on the fence between different chargers. --- ## 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/14203537-kc-125-mpxp-12v-1-25-amp-automatic-mini-pro](https://www.desertcart.co.uk/products/14203537-kc-125-mpxp-12v-1-25-amp-automatic-mini-pro) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
