NYI 12V 3000mAh DC Rechargeable Lithium ion Battery Pack 3Ah
Quick take
This compact NYI 12V rechargeable lithium-ion battery pack is designed for common 9 to 12.6V DC devices such as routers, CCTV cameras, LED strip lights, and some RC or DIY projects. Shoppers who bought it for replacement use report it works as expected and offers good value, but there is a practical limitation to plan around, it may cut off once the voltage drops below about 9V.
Pros and cons
Pros
- Rechargeable lithium-ion pack with a 3000mAh (3Ah) capacity and a 12V class output.
- Includes charging support and DC5521 connector options for flexible setup.
- Rated for up to 3A (max) output, which helps many small 12V DC devices run normally.
- Compact form factor (about 2.72 x 2.17 x 0.71 inches) and light weight (about 0.34 lb).
Cons
- May stop output when voltage falls below roughly 9V, which can be an issue for devices that require deeper discharge.
- Battery size limits runtime, so it is best for moderate power 12V accessories rather than high-draw setups.
- Compatibility depends on matching your device’s input voltage range and connector needs.
What buyers think
Buyer-review evidence is limited but consistent in a few ways. Several shoppers describe it as a straightforward, small replacement battery that works as intended. A recurring theme is practicality and value, with comments pointing to good overall quality for the size and price point. The most buyer-relevant limitation mentioned is that the pack may not discharge below about 9V before cutting off, which matters if your device expects a lower minimum input voltage.
What this battery pack is for
This NYI 12V rechargeable battery pack is meant for small DC electronics that run on 12V systems, especially where you want a compact portable or backup power source. It is commonly considered for devices such as routers, CCTV cameras, LED strip lights, wireless cameras, and certain RC cars or DIY tools, as long as their input requirements align with the pack’s 9V to 12.6V operating window.
Key specs that affect real-world fit
- Battery type and capacity: lithium-ion, 3000mAh (3Ah).
- Input and charging: charging input is listed as DC12.6V/1A, and it is intended to be charged using the 12.6V AC/DC charger (with charging time stated as under 3.5 hours when fully charged).
- Output range and current: output is specified as DC9.0 to 12.6V, with up to 3A (max) output.
- Size and portability: about 2.72 x 2.17 x 0.71 inches, around 0.34 lb.
Connection options (and why they matter)
For DC device batteries, compatibility is often less about voltage alone and more about the connector. This pack is built to support more than one installation approach, including direct connection and pairing with a DC5521 connector setup. If your device uses a DC5521-style barrel connector, these included connection options can reduce the need for extra adapters.
Pros and cons, in plain terms
When it makes sense to buy
- You need a small, rechargeable 12V-class battery pack for low to moderate power 12V DC devices.
- Your device input typically operates within a 9 to 12.6V range, not a tight single-voltage requirement.
- You want a compact power solution with charger support and connector options included.
When you should look elsewhere
- Your device needs reliable output below about 9V, since the pack may cut off before going that low.
- You expect long runtime for high-draw devices, because a 3000mAh pack is naturally limited in total energy.
- You are unsure about your connector type, and you do not want to confirm compatibility before ordering.
Verdict
The NYI 12V 3000mAh rechargeable lithium-ion battery pack is a solid fit for shoppers who want compact, rechargeable backup or mobile power for common 12V DC accessories like routers, CCTV, and LED strip setups. If your device can tolerate the pack’s voltage cutoff behavior and your connector needs match the included DC5521 approach, it is an easy, value-oriented option. If your device requires deeper discharge below around 9V or you need longer runtime for higher current loads, you will likely need a different capacity class or battery design.

FAQs
Will this battery power a router or CCTV camera?
It is designed for 12V-class DC devices and is listed as compatible with routers and CCTV cameras, as long as their input voltage requirements fall within the battery’s DC9.0 to 12.6V range and your device connector can be matched using the provided connection options.
What is the output voltage range?
The battery output is specified as DC9.0 to 12.6V. That range is important for device compatibility, especially if your equipment expects a narrow voltage window.
Does it stop working before the battery is fully depleted?
Some buyers report that it does not discharge below about 9V before cutting off. If your device needs power below that threshold, this could be a mismatch.
How long does it take to charge?
Charging time is stated as less than 3.5 hours for a full charge, using the 12.6V AC/DC charger intended for this battery.
What devices does it fit best?
It is positioned for smaller 12V DC devices such as routers, CCTV cameras, LED strip lights, wireless cameras, and some RC or DIY tools. It is best for moderate power applications where 3Ah capacity is sufficient.
What connector does it use?
It supports direct connection and DC5521 connector options, including a DC5521 female and male connector included with the kit. If your device uses a similar barrel connector, it should be easier to connect.
