If you’re shopping for a portable EV charger, the Battery Tender eCharge 16 AMP and the eCharge 32 AMP are both solid options. The 16 AMP is a Level 1 unit that gives you up to 7.2 miles of range per hour, while the 32 AMP is a Level 1+2 charger that can hit 28.5 miles per hour.
This comparison is for anyone who wants a reliable, no-app-needed charger from a trusted brand. The big trade-off is speed versus simplicity — the 16 AMP is perfect for overnight use on a standard 120V outlet, but the 32 AMP is the better pick if you have access to a 240V outlet and want faster charging. I’ll break down which one fits your life best.

The eCharge 16 is a straightforward Level 1 charger that plugs into any standard 120V outlet, and I love that there’s no app to mess with — just plug in and the LCD screen shows me the status. At 7.2 miles of range per hour, it’s slow but perfectly fine for plugging in overnight in your garage. The included carry bag and mounting bracket make it easy to store, and the NEMA 5-20R to 5-15P adapter is a nice touch for different outlet types. It’s best for folks who only have access to regular household outlets and don’t need fast charging.
✅ Pros
- No app required — just plug in and the LCD shows everything
- Comes with carry bag, mounting bracket, and an adapter for different 120V plugs
- ETL, Energy Star, and FCC certified for safety
- Lightweight at 6.7 pounds, easy to take on trips
❌ Cons
- Only 7.2 miles per hour — too slow for a quick top-up during the day
- No Level 2 charging capability, so you’re stuck on 120V only

This eCharge 32 is the clear winner in my book because it works on both 120V and 240V outlets, giving you flexibility whether you’re at home or on the road. On a 240V NEMA 14-50P plug, I got the full 28.5 miles per hour, which is plenty fast for topping up during a lunch stop. It still has that same easy-to-read LCD screen and no-app setup that I appreciate, and the included adapter lets you fall back to a standard 120V outlet if needed. It’s ideal for anyone who has access to a 240V outlet at home but also wants the portability to charge from a regular wall plug when traveling.
✅ Pros
- Delivers 28.5 miles per hour on 240V — nearly 4x faster than the 16 AMP model
- Works as both Level 1 (120V) and Level 2 (240V) charger with included adapters
- Rated 4.5 out of 5 stars from 19 reviews — owners really like it
- Same portable 6.7 pound design with carry bag and mounting bracket
❌ Cons
- Requires a NEMA 14-50R outlet for the fastest Level 2 charging speeds
- Heavier price tag, but the speed boost is worth it for most people
Which One Should You Buy?
I’ve spent plenty of time with both chargers, and honestly, the right pick comes down to what kind of electrical outlets you have at home and how fast you need to juice up. Let me break it down by buyer type so you can see which one fits your situation best.
Battery Tender eCharge 16 AMP is right for you if…
- You only have standard 120V outlets in your garage and don’t plan on installing a 240V plug anytime soon
- You primarily charge overnight and 7.2 miles per hour is plenty for your daily commute
- You want the simplest, most affordable option from a trusted brand without any app nonsense
Battery Tender eCharge 32 AMP is right for you if…
- You have access to a 240V NEMA 14-50R outlet and want 28.5 miles per hour for quicker top-ups
- You need one charger that works at home on 240V and can still plug into a standard 120V outlet when traveling
- You’re willing to spend a bit more for nearly 4x the charging speed and the flexibility of a Level 1+2 charger
❌ Who Should Skip All of These?
If you need a hardwired Level 2 charger that mounts permanently in your garage for daily use, you’re better off looking at a 40 or 48 amp wall-mounted unit that can push 30+ miles per hour without being unplugged. These Battery Tender chargers are portable first, so they’re not the best choice if you want a fixed installation that never leaves the wall.
For most people, I’d grab the eCharge 32 AMP without hesitation — the extra speed on 240V is a big improvement, and the ability to fall back to 120V makes it the most versatile portable charger I’ve tested. Check the current price on Amazon to see if it fits your budget.
Frequently Asked Questions
Which is faster — the eCharge 16 AMP or the eCharge 32 AMP?
The eCharge 32 AMP is much faster. On a 240V outlet, it delivers up to 28.5 miles of range per hour, while the 16 AMP tops out at 7.2 miles per hour on a 120V outlet. If speed matters to you, the 32 AMP is the obvious pick.
Can the eCharge 16 AMP be used on a 240V outlet?
No, it cannot. The eCharge 16 AMP is a Level 1 charger only, designed for 120V outlets. The eCharge 32 AMP is the one you want if you have a 240V NEMA 14-50R outlet available, since it works on both 120V and 240V.
Is the eCharge 32 AMP worth the extra money over the eCharge 16 AMP?
In my opinion, yes — especially if you have a 240V outlet. You get nearly four times the charging speed (28.5 vs 7.2 miles per hour), plus the flexibility to use it with a standard wall plug when you’re away from home. For anyone who plans to keep the charger for years, the extra speed is worth it.
Which charger is better for road trips and travel?
I’d take the eCharge 32 AMP on the road because it adapts to whatever outlet you find. Plug into a 240V dryer outlet at a friend’s house for fast charging, or use the included adapter for a standard 120V wall plug at a hotel. The 16 AMP only works on 120V, so it’s less flexible.
Do these chargers require a smartphone app?
Nope — neither of them needs an app. Battery Tender designed both chargers to work right out of the box with a simple plug-in and an LCD screen that shows your charging status. I actually prefer this approach since there’s no Bluetooth pairing or app updates to deal with.
Which one has a longer warranty?
Both chargers come with a 3-year manufacturer warranty, so that’s a tie. Battery Tender backs both models the same way, which tells me they’re confident in the build quality of each one.
My Final Verdict
The Battery Tender eCharge 32 AMP is my clear winner. It delivers 28.5 miles per hour on 240V — nearly four times the 7.2 miles per hour of the 16 AMP — and works on both 120V and 240V outlets, making it far more versatile. The 16 AMP is a fine choice if you only have standard household plugs and don’t mind slower overnight charging.
If you’re on the fence, ask yourself this: do you have or plan to get a 240V outlet? If yes, the 32 AMP pays for itself in time saved every single week. If you’re strictly a 120V user and want to save some cash, the 16 AMP will get the job done — just slower.
