This compact and lightweight device is equipped with advanced safety features, making it a must-have for any vehicle owner looking to prolong battery life and performance.

## Description

When your charger arrives in that little brown desertcart box, you'll probably be excited to rip it open and charge immediately, but take a moment to recognize the world's smartest battery maintainer you have in your hand. Note the sturdy sealed construction and quality components that allow us to back this smart charger with a 5 YR WARRANTY. This thing is built to last and endure years of trouble free use and unavoidable incidental elements like water and dust (unlike our competitors). 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 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 percent 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: Glad to own this Little Wonder for Charging batteries. - I was actually surprised, this company sent me a email asking if this charger worked and if I needed any help. This Charger Works wonderfully, I used it first on a battery setup that is 2x 18 AH batteries in parallel, only drained to little under 12 volts. And I have a Watt meter hooked up all the time so I can see the Volts and amp draw. And it has a constant LED light strip pulling 0.1 amps per hour out all the time. With my setup I was able to actually see the different charge states as it upped the voltage and adjusted. It took 3 days for the batteries to charge but for 0.75 amps with a constant 0.1 amp draw that's really good. The first 2 days was the more bulk charging. Then in float the last day from 13.1 to 13.6 that took the longest. But that's actually a good thing don't want to burn your batteries up. A few recommendations and ideas for future products. 1st would be to make the battery connecters SAE with permanent O ring attachment or Alligator clips that are battery tender cable usable. Having this option would mean you could quickly change batteries and leave the terminal connections on, or use Alligator clips in place when not available. 2nd idea is to I think it is.have a Solar power input friendly, but still portable version. maybe even with higher switchable amp charging like .75, 2, 4, and 10 amp. With SAE connector input for solar, and AC wall adapter when solar is not available for use. And for the solar have it at least 150 watt solar panel input 10amp max I think it is. This would give great options and friendly competition to other small chargers specially if you can get MPPT tech in it for solar to drop the voltage when the 12volt panels hit up to 20v in direct sunlight. So instead of 5amp at 20v you'd have like 7amp at 14.1 or something like that. I have a MPPT charge controller but don't know the exact change off my head for conversions. Granted MPPT would make it cost more, I think it would be huge for Solar Power Techies. Put a switch in to swap between AC or SOLAR. That way on Bad cloudy days if you need a charge, you can swap to AC in. 3rd idea if you do the solar type Idea, Have the Load SAE connector setup, with a auto shut off maybe even selectable auto shut off I think most are 10.4 but you might want to have the battery life even longer and have it auto shut off somewhere inbetween like a dimmer switch. Make it between 10.4 and 12 volt with a few indicators like 11.0, 11.5 12.0. I am really glad this company cares about their customer's. And Hope their business grows better for charging and maintaining batteries. This charger was actually a little difficult to find in the desertcart product list. And for the price, hard to beat for quality. I think having at least 1 charger/maintainer that has optional 12 volt solar in would greatly increase the chance for people to find their products, and would expand to who they sell to. I am very glad I got this little charger, all tho it takes awhile to charge 36 AHs. and I had to make a little wire adapter so I could hook this up and leave my LED lights on. It works Very well. I also used it to top off a 5ah battery which didn't take very long and the only thing that needs done to improve on what they already have is SAE for more connection options, so the customer has more versatility with the product. Specially since its dust and weather tough.
Review: Low power and bad instruction but definitely rejuvenate battery - There are many kind of Battery chargers and Jump-starters. I have Stretch limo, BMW SUV, Toyota V6, old Corvette350 and 1000cc Motorcycle. I have no way to drive all of them everyday. Some of them (especially motorcycle) are driven just once in month or two. Life of battery get shorten when it's not be fully charged. I also have Smart charger, conventional charger(it will overcharge if left connected), 2 trickle chargers and 2 jump-starters(portable battery to jump start cars). All of those functioned differently and used for different purpose. But I've never own desulfator/rejuvenator + trickle charger like this one before. Battery produce crystal deposit on surface of inside lead plates when it's low voltage (not fully charged status). There is no way to shake off this deposit/sulfate because it's inside of battery. Those deposit/sulfate reduce power of battery and shorten life of battery because it covers surface of lead plate. Desulfator (there are many brand on market) would "shake off" those deposit by sending high frequency high voltage pulse. This charger does Desulfation on first 5 stages changing process (I don't know what's second and third stage do) I connected this charger to my Limo's 750CCA (relatively large) battery. Limo constantly consume power when it's just sit (by security system etc). This battery drops from 12.3v to 11.8v overnight (Time to change battery, half dead). I use this charger for 3 cycles (connect>Flashing green>steady green. disconnect > reconnect>flashing green> steady green) Now Limo has 12.5v in the morning without charging overnight. I used it to my BMW X5 which has 950CCA AGM battery, It doesn't drop voltage in the morning after defulfated (without charged overnight). Those newer European cars consume 500mA when it's stand by (up to 30min after ignition off), and 50mA when sleep. So, newer cars especially European keep consuming battery power even when its ignition off. There are many kind of chargers. If you just want to start your car right away, at least start car after few minutes charge, this is not product you want. You should get bigger smart charger ($35-$75) This charger is 0.75A power. compare to larger charger 2-5-12A cycle. (14.4v x 0.75A = 13.65w, size of one room-lamp) My BMW lit all 13 small room lamps when I open one of its doors. It consume 5w x 13 = 65w. consuming more than this charger would produce by just opening one of doors. It takes hours to make your car being able to crank again with 0.75A charger. If you want make your car start right away, choose another kind. if your car park on street or concern if you strangle on parking lot or somewhere, you should get Jump-starter (portable battery, portable jump starter) it's also $35-$95 If you have RV or some kind of large vehicle constantly open doors in-out when it's stored or large alarm system consuming power, you should concern larger trickle charger (1.5A, 2A trickle charger) I will plan to use this charger for all of my cars/motorcycle (include everyday driven Toyota) once a week to shake-off sulfation/Chrystal deposit. Reason I put only 4 star is Low power (Keyline has bigger charger too) and horrible instruction. came with 12 pages instruction with bunch of mis-spelled and mis-instructed. You need good imagination/self translation to read instruction, especially reading LED lamp chart. "Steady" or "Flashing" ? "mot" means "most" or "not" etc. also green LED lamp shows "Processing" or "Done, monitoring". It doesn't show status of all 5 stages.
