Eunorau 48V 2A E-Bike Charger (US/CA)
The standard Eunorau 48V charger for US and Canadian outlets — a spare for home and office, or a replacement for a lost or failed unit. Eunorau specifies 54.6V output at 2A, a DC 2.1 barrel plug and a US AC plug. $49.
Who the 48V 2A Charger is for
Buy it if
- Keeping a second charger at work so you never carry one
- Replacing a lost, damaged or failed original charger
- 48V Eunorau owners who want the manufacturer's own unit rather than a generic
Look elsewhere if
- Your bike is not a 48V system — the R1 and R1+ are 72V and the EKIDS bikes are 24V
- You want faster charging: this is the 2A standard unit, not a 3A fast charger
- Your DC connector isn't a 2.1 barrel — check before ordering
54.6V at 2A
Eunorau specifies 54.6V output at 2A — the standard full-charge voltage for a 48V nominal lithium-ion pack.
US AC Plug, DC 2.1 Barrel
Supplied with a US AC plug for US and Canadian outlets and a DC 2.1 barrel connector on the bike side. Check your bike's charge port matches before ordering.
The honest ledger
Green flags
- 54.6V / 2A output, the correct full-charge voltage for a 48V lithium pack
- US AC plug, supplied for US and Canadian outlets
- Eunorau's own unit rather than a third-party charger of unknown quality
- Inexpensive enough to keep a second one where you park
Red flags
- Eunorau publishes no UL or ETL certification for this charger, so we don't claim one
- 2A only — it is the standard charger, not the 3A fast charger
- 48V systems only: wrong for the 72V R1 and R1+ and the 24V EKIDS bikes
- Country of manufacture is China, per Eunorau, if that matters to you
- Connector type (DC 2.1) must match your bike's port — confirm if you're unsure

What it covers
Manufacturing defects in Eunorau's original parts and components.
Eunorau states it continues to support the product after the warranty period as a manufacturer courtesy, and may ask only for shipping costs on replacement parts.
What you must do
- You are the original purchaser — the warranty does not transfer
- Proof of purchase (your Redtail order confirmation)
- Product registration with Eunorau right after purchase
- An e-bike check-up by a Eunorau specialist or dealer after the first year of use
Not covered
- Ordinary wear and tear — brake pads, rotors, spokes, grips, shifters, brake cables and casings, tires and tubes, chains, chainrings, cassettes, transmission gears
- Labor charges for part replacement
- Corrosion from moisture or heat, and cosmetic deterioration of the finish
- Damage from accident, abuse, stunt riding, racing, improper storage, or neglect
24-Month+ Limited Warranty issued by Eunorau Bikes, a Nevada corporation. Bikes bought for commercial use — rental fleets, delivery, sharing programs — get a 50% reduced warranty period. Full terms are published by Eunorau at eunorau-ebike.com/pages/warranty. Redtail coordinates warranty claims for bikes bought from us, so send it to us rather than to Eunorau: support@redtailebikes.com.
Manuals & documentation
In the box
Eunorau's spec sheet for this model lists a printed manual and a tool kit as included.
Any other document
Eunorau publishes display, controller, shock and accessory manuals across several files. Tell us which one you need and we will send you our copy, so you are not hunting through a supplier download hub.
Eunorau publishes display and component manuals rather than a per-bike user manual. We link only the manual Eunorau lists against this exact model. Need a document we haven't linked? Email support@redtailebikes.com and we'll request it from Eunorau.
Shipping, returns & support
Shipping
Free shipping on every electric bike within the contiguous United States (lower 48).
Orders are prepared and dispatched within 1–3 business days. Most e-bikes arrive within 5–10 business days after dispatch.
Ships via UPS, FedEx, or LTL freight for larger items, with tracking emailed at dispatch. Freight deliveries may need a scheduled appointment and a signature.
On delivery
Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours.
If a bike arrives dead, won't charge, throws an error code, or has a faulty component, it is covered under the manufacturer warranty and Redtail coordinates repair or replacement remotely.
Returns
Change-of-mind returns accepted only on unopened, factory-sealed items requested within 72 hours of delivery, with a 15% restocking fee plus return shipping. Once a box is opened or a bike is ridden, it is no longer eligible.
Order cancellations carry a 3% transaction fee, because card-processing fees are non-recoverable.
Alaska, Hawaii, U.S. territories, P.O. boxes, and remote areas may incur extra charges or be excluded — contact us before ordering. Full terms: Shipping Policy · Refund & Return Policy.
Frequently asked questions
Which Eunorau bikes does this charger fit?
It is the standard charger for Eunorau's 48V e-bikes, using a DC 2.1 barrel connector. It is NOT correct for the 72V R1 and R1+ dirt bikes or the 24V EKIDS bikes. If you're unsure, email support@redtailebikes.com with your model and we'll confirm.
How long does a full charge take?
That depends on the pack, not the charger. Eunorau publishes charge times per bike — 4–6 hours on the Defender, 5–7 on the META26, 5–8 on the SPECTER-S — and those figures are for this 2A standard charger.
Is this charger UL certified?
Eunorau publishes no UL or ETL certification for this charger, so we won't claim one. Note that several Eunorau bikes are themselves listed as UL certified; that is a separate certification from the charger.
How does it ship, and can I return it?
Parts and accessories ship within the contiguous U.S. and may ship separately from a bike, which can take longer. Inspect on arrival — damage or the wrong item must be reported with photos within 48 hours. Unopened change-of-mind returns are accepted within 72 hours with a 15% restocking fee plus return shipping; used parts and accessories are not returnable.
