I have a nissan leaf with a 3.3kw charging unit should I buy a 32amp or a 16amp unit and which would charge quickest
1319362
I have the 6.6kW charger and the Leaf charges almost 30% per hour fir the first 80-90%... It is effectively 2-3 hours of charging, if you don't wait for the last tiny bit and don't run it completely out.

Buy the 32 amp unit. It will not charge your current Leaf faster but you'll be glad you have when you lease your next Leaf.

To add to the comments here, the 30 Amp unit has a 6' longer cord, which may be important depending on your garage configuration, especially if you get a second chargeable vehicle in a two-car garage.

Higher voltage (220 vs 120) and higher current will charge ayour car faster; however check your owner manual to ensure compatibility;

The answer really depends on what you plan for the future. The 16 amp will work with your Leaf. It will charge you at 3.3kw. But if you plan to get another car that has a 6.6kw charging unit in the future, you will be limited with your 16 amp charger. Considering the cost of electrical installation and the charger. The difference in price of the charger isn't a lot. Also if the circuit you put in is rated for 16 amps (20 amp breaker) then you have to upgrade the breaker to 40 amp and possibly the wiring to 8 gauge or thicker. Just things to consider.

If you have the 3.3kw, you would buy the 16amp unit. The 30amp unit will not charge it any faster, unless you have the 6.6kw charger on the Leaf. It's the difference from about a 0 to full charge in 7 - 8 hours (3.3kw) versus a 0 to full charge in 3 1/2 - 4 hours (6.6kw).

Please check the Label under your system and take note of the Voltage (V), Current (A) and if possible the Power (W), example (19V 3.95A, 75W). This will help you Know the type of Charger you should buy for your system. Another option is to check for the PART NUMBER of the AC Adapter that came with your system. Search the for the Part Number or compatible Part Number of the AC Adapter that will be compatible for your system.

Absolutely! The Jr. will do and excellent job for your application. It is basically the same charger except the output is 3/4 amp instead of 1.25 amps of the battery tender. All this means is that it would take longer to get to full charge. Since it would be used for storage, you don't need a charger that could charge a completely dead battery quickly.

if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you

The better measurement for an electric vehicle charger is the kW ( kilo Watt) not the amperage and the EVPP-7216 has a 7.2 kW rating. Most electric vehicles manufactured in the past five years (over 95%) have either a 3.3 kW or a 6.6 kW onboard inverter. So the 7.2 kW charger will charge either the 3.3 kW or a 6.6 kW onboard inverter at 100% - as fast as the car will allow charging. Now to answer your first question; Article 625 of the National Electric Code (NEC) deals with the installations of EVs. NEC Sec. 625.21 Overcurrent Protection states: " EV equipment shall be sized for continuous duty... not less than 125% of maximum load." Charging EVs often takes several hours and pulling current at full load for several hours creates considerable heat which over time causes failures and fires. A 7.2 kW station has the potential to pull 32 amp. and 125% of 32 is 40. Actually, the reason it's a 7.2 kW is because the math was worked backwards and that was the maximum kW unit that could be placed on a 40 amp. breaker. So, for protection and safety the 30 amp. or 32 amp. unit must be placed on a 40 amp. breaker. In the real world over heating is a major concern, and in most cases if you max. out the amperage over an extended time period you will have a breakdown. So, all 30 amp EV chargers require a 40 amp. breaker and 40 amp. wire (#8 wire min.) With my background as an electrician, I expect to place my 30 amp dryer on a 30 amp circuit and my 50 amp range on a 50 amp circuit. I was confused when I wired the first 30 amp EV charger, I thought it needed to go on a 30 amp circuit just like the 30 amp dryer and I learned it actually needed to go on a 40 amp. circuit. I am surprised to see that many electrician put the 7.2 kW EV chargers on a 30 amp circuit, this is because the box said 30 amps. and electricians are used to the 30 amp. dryer going on a 30 amp circuit, with a 30 amp EV Charge the installation on a 30 amp circuit is not by code and not safe. -Mike

16 amp is the standard charging cable that comes with most electric cars because it plugs into a standard 110v house outlet. The 30 amp is for a 220v outlet like those for electric dyers. you need a 220v outlet wired to a 30 amp breaker in your house breaker box. the 30 amp will work/charge the volt.

The 2.0 amp will charge faster than the 1.0 amp. Both will charge s3 and s5. it is a wonderful little unit and it has quality looks and feel. I bought 4 of them for my cars. good luck.

It doesn't much matter unless your charging your battery very quickly, such as jumping it. Which isn't good for batteries anyway. I purchased the 1.1amp. I have a car that I don't drive very often the battery died and it took about a day or so to fully charge. Though slow its better for the battery. One nice feature about the 1.1 amp model is the cold charge feature. I use this feature in upstate NY because cold batteries should be charged even slower. Either way the .75 and the 1.1 amp models are both trickle chargers. So they will slowly charge your battery and turn on and off as needed. I'd say you can't go wrong with either but for 10 dollars more the 1.1 amp and it's winter charge feature is quite nice.

Accoding to CTEK web site, the recommended chargers for cars are the CTEK Multi-US4.3 (good) 7002 (better) or 25000 (best)

Check the rated output of your charger. I've charged mine with chargers rated from 1 to 2.1 amps. Obviously, it charges faster with more current.

Battery charger. If you want it to go faster u buy Lipo batteries but you will need a lipo charger. They do sell chargers that will charge both type of batteries

I haven't used it for the Spark, but it's probably overkill just as it is for my Nissan Leaf. I bought it anyway because my Leaf is leased. I reasoned that I may as well wire in something powerful enough for a likely more powerful charger in the next generation EV when my Leaf lease is up. I tend to lean toward overkill when it comes to technology, but I don't usually advise others to do the same. It's often cheaper to get what you need now and buy the upgrade later when you can really use it. Plus, a lower power charge station will still do just fine charging an EV with a higher capacity charger. Just not quite as fast. Happy charging whatever you decide!

Hello William T Wallace, Thanks for your message. Our charger has a max ratting of 30 amps. So if your house is pushing 240v at 30 amps then the charger can run at 7.2 Kw hr. But the Kw are determined by the BMID on your vehicle. Currently the Nissan LEAF 2013 charges at 6.6 Kw per hour. So to answer your question, yes our charger will give 6.6 Kw as requested from your vehicle. I hope this information help. If you need further assistance, feel free to contact us at 888-833-2148. Thanks for your time, AV Customer Service.

The higher the amp the more electrical energy is sent. The car will charge faster.

You wont have any problems. This is a great unit. run any charger just as fast as anything else.

The 12 amp setting charges at a rate of 5 miles added per hour of charge. The 8 amp setting charges at about 3 to 4 miles added per hour (on a Nissan leaf)

Use a 12v motorcycle battery charger or a lawnmower charger. You can even use a car battery charger just keep the charging rate under 2A. If you going to be using it for a scooter or something that doesn't provide a charge just get a trickle charger and use it on the weekends to keep it topped off.
