Talentcell 24V Lithium Ion Battery PB240A1 - Long-Run Portable Power

In this review the Talentcell 24V Lithium ion Battery PB240A1 stands out as a portable power pack for hobbyists and small equipment owners who need 12V, 24V and USB power on the go. The single biggest reason to consider it is the flexible multi-output design combined with a very high cell capacity, which makes it suitable for LED strips, CCTV and small electronics. The review focuses on real-world use, safe charging steps and how the pack performs compared with typical lead acid alternatives.

Key Features

• Multi-voltage outputs: Provides 24V, 12V and 5V outputs to run LED strips, cameras and phones without an additional converter.
• High capacity cells: The lithium cells are rated at 22400mAh (3.7V basis) giving extended runtime for low- to mid-power devices.
• Included charger: A 29.4V/0.95A AC/DC charger and cable are included so the pack is ready to charge out of the box when used as instructed.
• Clear charging procedure: The manual method - plug charger into AC first, switch battery on, then connect - reduces sparking when followed correctly.
• Distinct DC ports: Separate 24V (DC5525) and 12V (DC5521) ports with inner positive and outer negative reduce confusion when wiring devices.
• Portable form: Compact and relatively lightweight for its capacity, making it easier to move between locations than a lead acid equivalent.

Who It's For

This pack is well suited to users who need off-grid runtime for LED light strips, CCTV cameras, modems and small appliances that accept 12V or 24V DC, and who want a rechargeable, lighter alternative to lead acid batteries. It is also useful for photographers or event operators running low-power equipment like a 360 photo booth or mobile lighting for hours.

People who should look elsewhere include those whose devices require a perfectly constant 24V rail for sensitive equipment, or users who cannot follow the charging instructions precisely; the 24V output is not a regulated constant voltage and the pack requires the correct charger and switch sequence to avoid sparks.

Pros & Cons

Pros

• Flexible outputs let one pack power phones via USB and cameras or strips via 12V/24V ports.
• High nominal capacity offers long runtimes for low- and mid-power loads compared with small power banks.
• Included 29.4V charger and clear port labeling simplify setup and reduce guesswork.
• Compact build and weight make it more portable than comparable lead acid units.

Cons

• 24V output voltage is not constant and may not suit equipment needing a tightly regulated 24V supply.
• Charging and connection order must be followed exactly to avoid sparking, which may be inconvenient for some users.

Buyers who accept the non-constant 24V output and follow the charging procedure will find it good value for portable power.

Frequently Asked Questions

Do I need a special charger?
The pack ships with a 29.4V/0.95A AC/DC charger; use that or a specified replacement to charge safely.

Can I power low-voltage devices from the 24V port?
No, low voltage devices must not be plugged into the high voltage 24V port to avoid damage; use the 12V or 5V outputs instead.

What is the switching procedure for charging?
Plug the wall charger into AC first, switch the battery to I, then connect the charger to the battery to minimize sparking.
