Hybrid Power refers to the ability of a device to operate using multiple power sources. For NEBO’s site lights, this innovative technology ensures compatibility with:

- 110v Site-Compliant AC Power
- 220v-240v Domestic AC Power
- Built-in Rechargeable Batteries

The milliamp-hour (mAh) rating of a battery indicates its energy storage capacity.

To determine this value:

1. Identify the current output (in milliamperes)
2. Determine how long the battery sustains this output (in hours)
3. Multiply these two figures

Formula: mAh = Current (mA) × Time (hours)

Practical Example:
A battery delivering 100 mA for 5 hours has a capacity of:
100 mA × 5 hours = 500 mAh

This 500 mAh rating signifies that the battery can theoretically provide:

• 500 mA for 1 hour
• 250 mA for 2 hours
• Or any combination yielding the same total energy output

External elements which can influence the battery's real-world energy delivery, such as temperature and battery age potentially result in variations from the calculated mAh rating.

Also consider power loss through the process of transfer. See question "What’s the difference between rated capacity and actual capacity in power banks?" for more information.

Divide the batteries mAh by your device’s battery capacity, then multiply by 0.7 to account for energy loss during transfer.

Not necessarily. Higher mAh means more capacity but also larger size and weight.
Choose based on your specific needs and portability requirements.

Temperature plays a crucial role in the performance of runtimes, with both extremes of the thermometer posing significant challenges. When exposed to either intense cold or scorching heat, these portable energy sources experience a trifecta of issues: diminished battery capacity, prolonged charging periods, and potential harm to their internal cells. Consequently, your lights output may falter in very hot or frigid conditions, delivering less power than expected. To ensure optimal functionality and longevity, most perform best between 0°C to 35°C (32°F to 95°F).

Input refers to how fast the power bank itself can be recharged, while output
indicates how quickly it can charge your devices.

Most power banks are universally compatible, but it’s best to check if the output voltage and amperage match your device’s requirements.

USB-A is the standard rectangular port, USB-C is the newer, reversible oval port capable of faster charging, and Micro-USB is a smaller port often used for input charging on older products.

For our flashlights that use alkaline batteries (non-rechargeable), NiMH (nickel-metal hydride) or NiCd (nickel-cadmium) rechargeable batteries will work fine, but with slightly reduced performance. These batteries output a slightly lower voltage than an alkaline which results in the slightly reduced brightness and runtime.

Rechargeable Li-Ion (lithium ion) cells should NEVER be used in our non-rechargeable products. These batteries feature a much higher operating voltage that could damage our products. The only exception to this is any products that use lithium primary (non-rechargeable) batteries. 

Yes. All of our brands' flashlights have lumen ratings that are tested and verified to ANSI standards. ANSI is the American National Standards Institute and the organization responsible for defining what criteria a light must achieve in order to receive a valid lumen rating.

all lighting products under 100Wh (about 26,800mAh) are allowed in carry-on luggage. Always check with your airline for specific regulations.

The brightest flashlight we currently make is offered within the NEBO brand and is called the Davinci™ 18000. This flashlight is both the brightest in its Turbo (18,000 lumens) and High (10,000 lumen) modes. 

You can find it here.

Yes, ACG stands behind its products across all brands with a 2-year limited manufacturer's warranty. Any item purchased from an authorised dealer or authorised internet reseller that does not perform properly due to a manufacturer defect can be returned for a warranty replacement. This warranty does not cover normal wear and tear or batteries.

We are are delighted to be able to offer replacement battery options for a selection of our our flashlights and head torches.

We are afraid that we do not stock replacement parts/cables for our torches. Our products arrive from our factory as a sealed unit, which makes internal repairs very difficult. As a result, we do not carry a range of spares.
