How to choose E-Bike Chargers
The 6 products here all come from one store, Eunorau (eunorau-ebike.com, a US store with prices in dollars): five chargers and one charging safety station, priced $39 to $499 as checked on Oct 23, 2026. The chargers are the 24V 2A EKIDS charger at $39, the 48V 2A 2.0 at $49, the 48V 3A fast charger at $69, the 52V 4A FLASH charger at $79 and the 72V 10A R1 fast charger at $169; the 12-gallon safety station costs $499. Compare three listed numbers first: output voltage, current in amps and the DC plug. Output voltage times current is the charger's power in watts, for example 58.8V x 4A is about 235 W for the FLASH charger and 54.6V x 2A about 109 W for the 48V 2A.
The hard part is knowing which battery a charger suits, because the pages say little. Each title names a voltage, 24V, 48V, 52V or 72V, while the specification lists a different output: 29.4V, 54.6V (on both 48V chargers), 58.8V and DC83V; the pages do not explain how the two figures relate, and none names a battery model. Only the FLASH page adds a note, that the charger 'can only be compatible with EUNORAU FLASH', without saying which FLASH battery or what a 153B plug is. The R1 page gives no plug type, so it cannot be matched to a battery port. None of the five charger pages lists a charge time, and the 48V 3A page calls its charger fast with no charge time or comparison behind the word. Ask the store which charger your battery needs before ordering.
Every review here comes from Eunorau. Its shipping page says accessories and batteries go by FedEx or UPS in an estimated 5 to 9 days after 1 to 3 business days of processing; orders over $100 ship free and smaller ones pay $14.99, so each of the four chargers under $100 carries that fee on its own. If the local warehouse is out of stock, the item ships from an overseas warehouse in an estimated 10 to 15 business days, possibly without carrier tracking until it clears customs. Returns must be applied for within 7 calendar days of receipt, for a new, unused item complete in its original packaging, and you pay the shipping back; the terms page says shipping is charged only once, which the return page contradicts. The warranty page gives 24 months on original Eunorau parts but does not name these items, and it excludes damage from unapproved accessories or chargers.

Questions before you buy
How do I know which charger fits my e-bike battery?
Eunorau's pages do not settle it. They list output voltage, current and plug, but the titles say 24V, 48V, 52V and 72V while the outputs read 29.4V, 54.6V, 58.8V and DC83V, and no page names a battery model. The FLASH charger says it can only be compatible with EUNORAU FLASH, and the R1 charger lists no plug type. Ask the store which charger suits your battery before you order.
How long does an e-bike charger take to charge a battery?
None of the five charger pages gives a charge time. They list output current of 2A, 2A, 3A, 4A and 10A (the R1 charger's output line reads DC83V-10A), and two are titled fast chargers. Weight is listed for two of the five, 0.84 kg for the 48V 3A and 1.08 kg for the 52V 4A. For a charge time, ask the store for your battery and charger pair.
What is an e-bike charging safety station?
Eunorau's 12-gallon station is an aluminum alloy container, 23.23 x 18.11 x 35.04 inches (590 x 460 x 890 mm), with 6 charging ports, outside and inside switch control, a smoke alarm and a movable shelf, priced at $499. The page's note says batteries and chargers are not included. It names no compatible models, gives no interior dimensions, weight or shelf load limit, and shows no certification or fire rating for the smoke alarm.
Does Eunorau charge for shipping a charger?
Its shipping page says orders over $100 ship free and smaller orders pay $14.99, with a possible remote-area charge, so the $39, $49, $69 and $79 chargers fall under the fee on their own. Delivery is an estimated 5 to 9 days after 1 to 3 business days of processing, or 10 to 15 business days from an overseas warehouse if the local one is out of stock, with possibly no tracking until customs.
Can I return an e-bike charger?
Eunorau's return page gives 7 calendar days from receipt to apply. The item must be new and re-sellable and complete with its original packaging, and you ship it back within 7 days at your cost; the refund is in full when the fault is Eunorau's or minus the shipping cost when the reason is yours. The terms page says shipping is charged only once and there is no restocking fee, which does not match.
