Quick take
The first thing to sort out when your ebike battery runs down is not brand or price; it's voltage. A 36V lithium battery needs a charger that outputs around 42V, while a 48V battery needs a 54.6V output. This group of four chargers includes two 42V 2A options, one 54.6V 2A charger, and one 3A charger aimed at 36V Huffy e-bikes with a 3-prong connector. The right pick depends on your bike's battery voltage, the plug shape, and whether you want a faster charge.
Quick take
- Lowest price: the 42V 2A Jetson charger at $22.99, for 36V lithium batteries.
- 48V option: the 54.6V 2A AUGALA charger at $37.99, for 48V lithium packs.
- Fastest charge: the 3A Huffy charger at $104.42, for 36V Huffy e-bikes with a 3-prong plug.
- Balanced 36V option: the 42V 2A AUGALA charger at $27.54, with a 5.5x2.1mm plug and a converter.

Product notes
Fast Charger For 36V Battery Electric Bike Scooter Power Supply 42V 2A Adapter
This AUGALA charger outputs 42V at 2A, matching a 36V lithium battery. It carries UL 1012, UL 1310, UL 60950-1 and UL 62368-1 certification. The package includes a 5.5x2.1mm DC plug and a converter to 8mm 3-prong, which gives you flexibility if your bike uses that plug. The 2A rate is the standard for this voltage class, so it will get the battery charged without pushing more current than the pack may expect. The limitation is that 2A is not the fastest in this group, and the charger is not designed for 48V batteries or for lead-acid packs.
New Fast Charger 54.6V 2A For Lithium Battery Electric Bike Scooter Power 48V
This charger is the only one in the group with a 54.6V output, so it is the correct match for a 48V lithium battery. It uses a 5.5x2.1mm DC connector and includes a converter cable. The 2A rate is the same as the other AUGALA charger, but it is not the fastest in this group. The limitation is that the 54.6V output will not work on a 36V battery, so you need to confirm your battery voltage before ordering. Because the charger is designed for 48V packs, do not use it on a 36V bike.
42V 2A Charger for Jetson Electric Bike Charger, Electric Scooter Adapter
This is the lowest-priced charger in the comparison, and it is specifically named for Jetson electric bikes and electric scooters. It outputs 42V at 2A, which suits a 36V lithium-ion battery, and it works with 42V 2A, 42V 1.5A and 42V 1A chargers. It has an LED light that switches from red to green when charging is complete, plus protection against overcurrent, overvoltage, short circuit, overheating and overcharge. The limitation is that the 2A output is slower than the 3A option, and the charger is not intended for lead-acid batteries.
fast 3A battery Charger for 36v Huffy cadence vertis electric bike (3 prong
This charger delivers 3A to a 36V Huffy e-bike, making it the highest-current option in the group. It uses a 3-prong plug, and the description asks you to send a picture of your charging port and battery voltage if you are unsure about compatibility. The listing uses inconsistent Huffy model names, so confirm your charging port and battery voltage before ordering. The limitation is that the listed price is the highest in this group, and the 3-prong connector only fits bikes that use that exact plug.
Final recommendation
- For a 48V battery: choose the New Fast Charger 54.6V 2A For Lithium Battery Electric Bike Scooter Power 48V. It is the only charger here with a 54.6V output.
- For a 36V battery where the listed price matters most: the 42V 2A Charger for Jetson Electric Bike Charger, Electric Scooter Adapter is the lowest-price option in this guide.
- For a 36V battery with connector flexibility: the AUGALA Fast Charger For 36V Battery Electric Bike Scooter Power Supply 42V 2A Adapter adds a converter cable and carries the listed UL certifications.
- For a Huffy e-bike with a 3-prong port: the fast 3A battery Charger for 36v Huffy is the only 3A, 3-prong unit in this set, so it is the one to match.
