U23 FEATURES
Every feature, with the original product detail intact.
Original A+ visuals carry the product story; the page adds a consistent reading order, confirmed specifications and the operating context that matters.
Starting support
Built for the compatible 12V vehicle.
The documented fit reference is up to 6.0L gasoline or 3.0L diesel. A full charge can provide up to 25 starts using a standard 1.5L sedan as the reference; real results vary with battery health, temperature and engine condition.
Capacity
Power that stays ready between trips.
The 8,000mAh / 29.6Wh battery is designed for repeated roadside readiness. Keep U23 charged and use it only on the compatible 12V vehicles listed in the manual.
Vehicle fit
Built around the 12V vehicle routine.
Use the U23 with compatible 12V cars within the stated engine range. Check the vehicle’s battery condition and follow the manual’s clamp sequence before attempting a start.
Device power
A useful power bank between roadside calls.
Recharge through Type-C 5V / 2A in about 3–4 hours; the USB-A port provides 5V / 2.4A for everyday phone and small-device charging.
Emergency light
See the connection, signal the situation.
The original product callout keeps its 150LM value. The manual specifies a 5W light with Steady, Flashing and SOS modes for roadside use.
Smart clamp safety
Protection made visible at the clamp.
U23’s smart-clamp system is described with 10 total safety protections. This graphic preserves the visible 6-in-1 core safeguards: reverse polarity, short circuit, over-voltage, over-current, overheat and over-discharge. U23 is safety tested to UL 2743; the product-level test-report scope is shown in Safety & Compliance.
Ready where you park
One small kit for routine and unexpected stops.
Keep the U23 accessible for commutes, weekend trips and the moments a vehicle needs a little backup. Store it dry, inspect the clamp before each use and recharge after use.
Four-step start
Connect deliberately. Start with confidence.
Charge U23 to at least 50%, connect the smart clamp, confirm its green indication, then start the vehicle within 30 seconds. Disconnect as directed once the vehicle has started.
