Individual Product Breakdown
I spent time testing each Battery Tender eCharge model to see how they handle real-world charging, from overnight top-ups to full-speed home fills. Here is my honest take on all three.
Battery Tender eCharge 16 AMP EV Charger – Level 1 Portable
120V input | 16A output | 7.2 miles/hour | 6.7 lbs | ETL & Energy Star certified
- Efficient Charging: Easily select charging output amperage to adjust for...
- Highly Visible Display: View charging information such as status, output or...
- Versatility: Includes adapter for typical 120V home plugs which are present...
This little guy is built for simplicity. I plugged it into a standard 120V outlet in my garage and it worked right away with no app or setup. The LCD display shows charging status clearly, and the carry bag makes it easy to toss in the trunk for trips. Just keep in mind that 7.2 miles of range per hour is slow — it is really meant for overnight charging or topping off at a friend’s house.
✅ Pros
- Plugs into any standard 120V outlet with included NEMA adapter
- Lightweight at 6.7 pounds with a carry bag for portability
- No app required — just plug in and charge
- 3-year manufacturer warranty included
❌ Cons
- Very slow charging speed at only 7.2 miles per hour
- No Level 2 240V support — limited to 120V only
Battery Tender eCharge 32 AMP EV Charger – Level 1+2 Portable
120V/240V input | 32A output | 28.5 miles/hour | 6.7 lbs | J1772 connector
- Convenient Charging: Easily select charging output amperage to adjust for...
- Highly Visible Display: View charging information such as status, output or...
- Versatility: As a Level 1 or Level 2 charger, the eCharge 32 is the perfect...
This is my favorite travel companion. I love that it works on both 120V and 240V outlets, so I can use it at home on my dryer plug and still take it on road trips. At 28.5 miles per hour on Level 2, it charges my car overnight without any problem. The only downside is the included NEMA 14-50 plug is bulky, and you will need an adapter if your home has a different outlet.
✅ Pros
- Dual-voltage Level 1+2 works with both 120V and 240V outlets
- Fast 28.5 miles per hour charging on Level 2
- Portable design at 6.7 pounds with a carry bag
- No app required — simple plug-and-charge operation
❌ Cons
- Only comes with a NEMA 14-50 plug — you may need adapters
- Not as fast as the 40A model for daily home use
Battery Tender eCharge 40 AMP EV Charger – Level 2 Mounted Indoor Outdoor
240V input | 40A output | 36 miles/hour | 25ft cable | RFID security | Indoor/outdoor
- Convenient Charging: Easily select charging output amperage to adjust for...
- Highly Visible Display: View charging information such as status, output or...
- Versatility: As a Level 2 charger, the eCharge 40 is the perfect solution...
This is the one I keep on my garage wall. With 36 miles of range per hour, it fills my EV from empty to full overnight without any stress. The 25-foot cable reaches both my cars easily, and the RFID card access is a nice touch if you want to control who uses the charger. It is a permanent installation, so you lose portability, but for daily home charging this is the fastest and most polished option Battery Tender offers.
✅ Pros
- Fastest charging at 36 miles per hour with 9.6kW power
- Flexible 25ft cable reaches across a two-car garage
- RFID cards provide secure access for multiple users
- Can be hardwired or plugged in for installation flexibility
❌ Cons
- Not portable — it is designed for permanent wall mounting
- Requires a 240V outlet (NEMA 14-50) or hardwiring
Which One Should You Buy?
I know picking the right charger can feel overwhelming, but the best choice really comes down to where you charge and how fast you need to fill up. Let me break it down by buyer type.
Battery Tender eCharge 16 AMP is right for you if…
- You only have a standard 120V outlet available and need a simple plug-and-charge solution
- You travel frequently and want a lightweight 6.7-pound charger that fits in a carry bag
- You only drive short distances daily and 7.2 miles per hour is plenty for overnight top-ups
Battery Tender eCharge 32 AMP is right for you if…
- You need one charger that works at home on a 240V outlet and on the road with a 120V plug
- You want fast 28.5 miles per hour charging but still need portability for trips
- You rent or plan to move and want a charger you can easily take with you
Battery Tender eCharge 40 AMP is right for you if…
- You own your home and want the fastest permanent charging at 36 miles per hour
- You have a two-car garage and need the 25-foot cable to reach both parking spots
- You want RFID security to control who can use the charger at your home or workplace
❌ Who Should Skip All of These?
If you own a Tesla and want native Supercharger access without an adapter, or if you need a smart charger with Wi-Fi scheduling and app control, you will be better off with a different brand entirely. These Battery Tender models are intentionally app-free, so anyone who wants remote monitoring or time-of-use scheduling should look elsewhere.
For the vast majority of homeowners who just want a fast, reliable, and simple charger for daily use, my pick is the Battery Tender eCharge 40 AMP. It delivers the best speed at 36 miles per hour and the most features for a permanent home installation.
Frequently Asked Questions
Which is better for home charging: the eCharge 32A or the eCharge 40A?
For a permanent home install, I recommend the eCharge 40A every time. It delivers 36 miles per hour compared to the 32A’s 28.5 miles per hour, so you get a noticeably faster fill. The 40A also includes RFID security and a 25-foot cable that reaches across a two-car garage, while the 32A is designed as a portable unit. Unless you need to take your charger on the road, the 40A is the better daily driver.
Is the eCharge 16A enough for overnight charging?
It depends on how much you drive. At 7.2 miles per hour, the 16A adds about 86 miles over a 12-hour overnight session. If your daily commute is under 50 miles, that is plenty. But if you drive long distances or come home with a nearly empty battery, you will want the 32A or 40A to avoid waiting all day to recharge.
Can I use the eCharge 32A on a regular 120V outlet?
Yes, absolutely. That is the whole point of the Level 1+2 design. The 32A comes with a NEMA 5-15P adapter so you can plug it into any standard household 120V outlet when you are away from home. At home on a 240V outlet, it switches to Level 2 and charges at 28.5 miles per hour. This dual-voltage flexibility is why I call it the best travel charger of the three.
Is the eCharge 40A worth the extra money over the eCharge 32A?
For a permanent home setup, yes, I think so. The 40A charges faster at 36 miles per hour versus 28.5 miles per hour, and the 25-foot cable gives you way more reach than the 32A’s shorter cord. You also get RFID access control, which is handy if you share the charger with family or coworkers. The trade-off is that the 40A stays mounted on your wall, while the 32A can travel with you.
Do any of these chargers require a smartphone app?
Nope, none of them do. Battery Tender specifically designed the eCharge line to work without an app. You control the charging amperage directly on the unit and view status on the LCD display. If you like keeping things simple and hate dealing with app connectivity issues, these chargers are a refreshing change.
What size breaker do I need for the eCharge 40A?
The eCharge 40A pulls a maximum of 40 amps, so you need a 50-amp breaker for a safe installation. It uses a NEMA 14-50 plug, which is the same outlet many electric ranges and dryers use. If you are hardwiring it instead of plugging it in, make sure your electrician uses a 50-amp breaker and appropriate gauge wiring.
My Final Verdict
I am giving the top spot to the Battery Tender eCharge 40A. It charges at 36 miles per hour, comes with a 25-foot cable that actually reaches both cars in my garage, and the RFID security is a nice bonus for shared use. If you need portability, the 32A is my runner-up because it works on both 120V and 240V outlets and still delivers a solid 28.5 miles per hour on Level 2.
If you are still on the fence, ask yourself this: do you own your home and want the fastest daily charging? Get the 40A. Do you rent or travel with your charger? Get the 32A. The 16A is only for those who have no 240V outlet and drive very short distances.
