A123 charging needs vary sharply. Some setups need a regulated supply for hobby-grade balance chargers, while security cameras use rechargeable 123A cells with different dimensions and chemistry. Make the match before purchasing, especially because several popular charging options in this roundup serve AA, powersports, or general household batteries rather than A123 packs.
The Leading Options At A Glance
T POWER 60W AC DC Adapter for Balance Chargers
Battery Tender Junior 12V Charger and Maintainer 750mA
FARSAIL 16-Pack 123A NiMH Batteries and Charger
FARSAIL 4-Pack ICR17335 NiMH Batteries and Charger
Tenergy TN480U 8-Bay AA AAA Battery Charger
Tenergy Universal Rechargeable Battery Charger
FARSAIL 4-Pack 800mAh ICR17335 NiMH Batteries
A Breakdown Of The Leading Choices
A replacement power supply makes sense on a workbench occupied by older hobby battery chargers. This adapter accepts 100V to 240V AC input and provides a nominal 12V DC output at 60W, with an 11V to 18V output range for listed compatible equipment.
Unlike the camera-battery sets later in the roundup, it supplies power rather than charging cells directly. Hobbyists using compatible Tenergy, Turnigy, SKYRC, or KYRC balance chargers benefit most, while casual camera users should look elsewhere.
What Stands Out
- Broad AC input supports use across regions with 100V to 240V power.
- The 60W rating suits several listed 45W, 50W, and 60W charger families.
- Variable DC output provides fit for chargers operating across 11V to 18V.
- It can restore a bench setup after an original adapter fails.
Points To Note
- It is a power adapter, not a standalone A123 charger.
- Connector and polarity must match the original charger wiring.
- Owners commonly report confusion because many similar charger models look alike.
Key Attributes
Built With In Mind
This option suits hobbyists repairing a compatible bench charger whose original power supply has failed.
Consider Something Else When
Choose FARSAIL 123A Rechargeable Batteries instead for Arlo cameras rather than hobby balance charging equipment.
Storage maintenance is the clear purpose here, not lithium hobby-cell charging. The Battery Tender Junior uses 750mA to bring a compatible 12V lead-acid battery toward full charge, then moves into float mode to help manage voltage during storage.
That behavior fits motorcycles, ATVs, and similar powersports parked for weeks at a time. Compared with the T POWER adapter, it performs a complete charging sequence, but its lead-acid focus makes it unsuitable for A123 or Arlo camera batteries.
Advantages To Know
- The 750mA output suits low-current maintenance charging.
- Four-stage charging moves from initialization through bulk charging, absorption, and float.
- Flooded, AGM, gel, and other compatible 12V lead-acid batteries are supported.
- Automatic float operation reduces day-to-day supervision during seasonal storage.
Trade Offs
- It has no stated charging support for A123 lithium cells.
- 750mA is conservative for large-capacity vehicle batteries and may take longer.
- Long-term lead-acid storage still benefits from periodic battery and connection checks.
Quick Facts
Made For
Seasonal riders benefit most from the automatic transition into storage-maintenance float mode.
Look Elsewhere When
T POWER 60W AC DC Adapter for Balance Chargers is the relevant choice for compatible hobby balance chargers.
Large camera installations create a different charging problem, and this 16-cell set prioritizes rotation and spare coverage. The FARSAIL package pairs rechargeable 123A NiMH cells with a charger for listed Arlo cameras, CR123A-powered flashlights, consoles, appliances, calculators, and other compatible devices.
The cells are rechargeable rather than disposable, but 123A is not interchangeable with cylindrical A123 packs. You gain a convenient camera-battery group, not a balance charger for hobby lithium assemblies.
What Works In Its Favor
- Sixteen cells reduce the inconvenience of keeping several camera housings powered at once.
- The included charger supports the same recharge-and-rotate routine.
- Compatibility spans numerous listed Arlo camera models.
- Use beyond Arlo products covers flashlights and assorted household electronics.
Small Caveats
- Confirm the battery compartment accepts rechargeable 123A cells before removal.
- Device runtimes can vary with camera activity, temperature, and battery condition.
- These NiMH cells do not charge in an A123 balance charger.

Who It Suits Best
Small Arlo installations benefit from a compact four-cell rotation with a dedicated charger.
A Better Fit Elsewhere
FARSAIL 16-Pack 123A NiMH Batteries and Charger suit households that need more camera cells and flashlights.
Eight bays turn this into a practical charging station for a drawer full of reusable AA and AAA cells. The Tenergy TN480U supports NiMH and NiCd batteries, with an LCD for checking progress and two input options listed as Micro USB and USB Type-C.
Independent charging is useful because mixed cell sizes do not force you to create artificial pairs. Still, this charger has no A123 or 123A bay, so it serves household electronics rather than either battery format in this roundup.
Strong Points
- Eight bays reduce the number of charging cycles needed for larger cell collections.
- Mixed AA and AAA charging avoids pair-based batch management.
- The display provides a visible view of charging progress.
- Two cable standards improve compatibility with different power sources.
- Both NiMH and NiCd cells are supported.
Details To Watch
- Do not place 123A or cylindrical A123 cells in this unit.
- Software and accessory availability can depend on the selected package variant.
- Keep unused bays clear and keep the charging surface dry.
Technical Sheet
Made For
Households managing many AA and AAA rechargeable cells benefit from eight-bay capacity.
Reach For A Different Pick When
Battery Tender Junior 12V Charger and Maintainer 750mA serves a parked motorcycle rather than household cells.
A mixed battery drawer calls for broader format coverage than the TN480U provides. This Tenergy model accepts up to four AA, AAA, C, or D cells through individual channels, plus two dedicated positions for 9V batteries. Automatic current selection reduces the need to configure each format manually.
The LCD and automatic charge-discharge function make it more involved than a basic four-slot charger. You still need the correct cell, polarity, and chemistry for each bay, and A123 packs do not fit.
What Makes Sense
- One charger covers cylindrical household cells and rectangular 9V batteries.
- Separate 9V positions improve format flexibility.
- Automatic current selection simplifies mixed-size charging.
- The LCD provides a central view of the charging process.
- Charge-discharge functionality adds flexibility for maintenance routines.
Possible Compromises
- The larger format range makes it bulkier than an AA and AAA-only charger.
- Every cell must still be inserted in the correct size, polarity, and chemistry.
- It offers no stated compatibility with Arlo 123A or hobby A123 batteries.
Whose Shelf It Belongs On
This charger fits homes maintaining rechargeable AA, AAA, C, D, and 9V batteries in one place.
Swap It Out When
Tenergy TN480U 8-Bay AA AAA Battery Charger suits collections limited to AA and AAA cells.
Four labeled 800mAh cells form a straightforward replacement group for listed Arlo cameras. The FARSAIL ICR17335 NiMH set is also presented for compatible flashlights, making it more versatile than a camera-only disposable-cell routine while remaining distinct from A123 hobby packs.
You handle charging through a separate compatible charger, so the product page and camera instructions deserve close attention. The 800mAh marking provides a basis for comparing capacity, though actual device runtime varies with recording load and conditions.
Where It Delivers
- The 800mAh rating supports a practical capacity-focused replacement decision.
- Four cells suit a typical small rotation pattern.
- Compatibility covers several listed Arlo models and compatible flashlights.
- Reusable NiMH cells suit recurring charging routines.
Factors To Consider
- A separate charger may be needed for these 123A cells.
- Do not treat 123A as a direct replacement for a cylindrical A123 pack.
- Camera compartment clearance and battery polarity deserve checking before installation.
- High-activity cameras may require more frequent rotation than lightly used devices.
Core Details
Who Will Love This
Arlo households wanting four 800mAh rechargeable cells value the compact replacement quantity.
Where A Sibling Pick Shines
FARSAIL 16-Pack 123A NiMH Batteries and Charger suit larger camera installations needing more spare cells.
A Match Matters More Than Charger Size
Before choosing among A123 battery chargers, distinguish the formats involved. A123 packs are cylindrical lithium cells often used in multi-cell hobby packs, while 123A cells are compact rechargeable or primary batteries used by selected cameras and flashlights. A charger suitable for one does not automatically fit the other.
Chemistry and cell format
Lithium hobby packs commonly require a charger designed for their chemistry, cell count, connector, and balance requirements. A 123A camera charger may instead use a dedicated bay and must match the cell’s electrical design. Verify both dimensions and chemistry before ordering.
Connections and balance requirements
Hobby battery systems often use balance connectors so individual cells can be monitored during charging. A power adapter cannot replace that monitoring function, and a camera charger may have no balance lead at all. Connector polarity and charge current also need to match the connected equipment.
Device and battery count
One Arlo camera may need only a few spare cells, while eight cameras can justify a larger set. Mixed AA and AAA collections call for multi-bay charging, whereas a 12V motorcycle requires a lead-acid maintainer. Count the batteries, their sizes, and the devices they serve before choosing.
Common Charging Mistakes To Avoid
Wrong Turns To Avoid
A123, 123A, AA, AAA, and 9V batteries look different and charge differently. Do not rely on a shared label alone, and do not place one chemistry into a charger designed for another. A close visual match is not enough.
When Paying More Pays Off
Higher-tier equipment can justify more charge when you need independent bays, detailed status displays, automatic cell handling, or broader format support. A compact camera-cell set may offer better ownership fit than a large charger with unused capabilities. Pay for useful coverage, not simply for a larger box.
Frequently Asked Questions
Is an A123 battery the same as a 123A battery?
No. A123 and 123A describe different formats with different dimensions and applications. Confirm the exact battery marking and device requirements before selecting a charger.
Can the T POWER adapter charge A123 cells directly?
No. It supplies DC power to compatible balance chargers but does not perform cell balancing or charging by itself. The connected charger must support the battery’s chemistry and pack configuration.
Which option suits Arlo cameras?
The FARSAIL rechargeable 123A sets are intended for listed Arlo models. Confirm camera compatibility, physical clearance, polarity, and the required charging method before replacing installed cells.
Can rechargeable 123A cells replace disposable CR123A cells?
Only in a device explicitly designed for rechargeable 123A cells. Voltage behavior and termination requirements can differ, so verify the equipment instructions rather than relying on shape alone.
What matters most when choosing a charger?
Battery chemistry, dimensions, connector type, charge current, and required balancing function matter most. Device count also determines whether a four-cell, eight-bay, or multi-format design will fit your routine.
Final Thoughts
The right charging choice depends on the format actually sitting on your workbench or inside your cameras. T POWER serves compatible hobby balance chargers, Battery Tender Junior supports 12V lead-acid storage, and the FARSAIL sets target rechargeable 123A cells. Match the connector, chemistry, and battery count before deciding.
