Shop e-bike chargers
The right e-bike charger keeps your battery ready for your next ride, whether you're charging at home, at work or on the go. Chargers convert mains power into the voltage your battery needs and control the charging current, measured in amps (A). Each manufacturer designs its chargers to work with specific batteries, connectors and charging electronics, so it's important to match the brand and system generation. Keep your main charger at home and a compact second charger at the office, and you can head home with a full battery without carrying one back and forth. Planning a ride with a short charging stop? A fast charger helps you get moving again sooner.
Why an additional e-bike charger makes sense
Having your own additional charger means you don't have to rely on the one that came with your bike.
- Charge where you park: Keep a second charger at the office or your vacation accommodation instead of carrying one with you.
- Charging time to suit your needs: Choose 2, 4 or 6 A to match the charging speed to your daily routine.
- Safe for your system: An approved charger is matched to the connector, battery and charging electronics.
Charging current compared – from compact chargers to fast chargers
The key difference between chargers is how quickly they recharge your battery. Charging current, measured in amps (A), tells you the maximum current a charger can deliver. Higher amperage means shorter charging times, but usually a larger charger too. Before choosing your charging speed, check compatibility – your charger must match your battery's brand and system generation.
2 A compact chargers – lightweight for travel
Compact chargers operate at around 2 A. They charge more slowly, but fit easily in a backpack, saddle bag or desk drawer.
- In our range: the Bosch Compact Charger for the eBike-System 2, the 2A Charger for the smart system, the MAHLE X35 Charger and the Shimano EC-E6002 with 1.8 A.
- Best if: you charge overnight or while you're at work and want a lightweight second charger for the office or travel.
4 A standard chargers – the all-rounders
The 4 A class is the everyday choice for many systems. These chargers are noticeably faster than compact chargers while remaining easy to carry.
- In our range: 4 A chargers from Bosch, Giant, TQ, SRAM and MAHLE, plus the Shimano EC-E8004 for older SHIMANO STEPS systems.
- Best if: you commute every day and want to recharge your battery quickly between rides.
6 A fast chargers – for short charging stops
Fast chargers deliver 6 A and save the most time with larger batteries. If you ride several times a day, they help reduce the time your bike spends charging.
- In our range: the Bosch Fast Charger for the eBike-System 2 and the Giant Smart Charger with 6 A.
- Best if: you use large batteries and want to recharge between a morning and afternoon ride.
Choosing the right e-bike charger – find the right match for your battery
Start with the label when choosing a charger for your e-bike battery. It tells you the manufacturer and system generation. Bosch uses different charging ports for the smart system and older system generations. Giant uses different chargers and connectors depending on the EnergyPak system. Next, choose the charging current. Finally, check the mains plug, as some chargers are available with either an EU or UK plug.
Is there a universal electric bike charger, or can I use a charger from another manufacturer?
We strongly advise against it. Bosch warns that incompatible chargers can shorten battery life or cause other damage. Shimano specifies which battery and charger combinations should be used, as other combinations can lead to overheating. System generation also matters within the same brand: Bosch chargers for the smart system cannot charge batteries from earlier Bosch systems.
Is an e-bike fast charger worth it for every battery?
A fast charger is most useful for large batteries and short charging stops. Giant confirms this: The 6 A Smart Charger charges large batteries faster, while the 4 A version is easier to carry. However, the battery ultimately determines the charging rate. Bosch's smart system adjusts the charging current to each battery, and some are deliberately charged at a lower current. If you usually charge overnight, a fast charger offers little benefit.
Can I use my e-bike charger when traveling abroad?
Check the input voltage and mains plug – both are listed on the charger's label. The Shimano EC-E6002 operates at 100 to 240 volts, although Shimano advises against using travel voltage converters. According to the product specifications, Bosch chargers for the smart system are designed for 220 to 240 volts. We also carry the Bosch 2A and 4A Chargers with UK plugs.
Can I charge the battery on the bike or when removed, and do I need a charging adapter?
Both are possible, depending on the system. When charging on the bike, plug the charger into the charging port and don't move the bike while it's charging. Some Shimano batteries can be charged directly when removed, while others require the SM-BTE60 or SM-BTE80 charging adapter. Close the charging port cover afterward to prevent dirt from building up and stopping the connector from fitting properly.
