pemacom Up to 300% Longer Runtime Rechargeable Batteries with Charger (4 AA + 4 AAA, 1.5V Lithium)
Quick take
This pemacom kit bundles 4 rechargeable AA and 4 rechargeable AAA lithium batteries with a 10-slot charger and storage box, designed to deliver stable 1.5V output for common AA/AAA devices. It is best for households with remotes, controllers, cameras, and other higher-drain electronics that benefit from consistent voltage. The main buying caveat is that some buyers feel the charging speed is not as fast as the marketing suggests, and you will need a compatible 5V power adapter to use the charger.
Pros and cons
Pros
- Includes 8 lithium rechargeables (4 AA, 4 AAA) plus a charger/storage case to keep everything together.
- 1.5V constant output design, aimed at avoiding voltage drop during discharge.
- Built-in multi-layer safety protection and an LED charging indicator.
- Fast-charge concept via USB-C input, intended for quicker top-ups.
Cons
- Charging speed may not match the “fast” claim for every setup, based on limited review feedback.
- Slots are not interchangeable (AA and AAA positions are dedicated).
- You need a 5V power adapter (not included) to fully use the charging case.
- One report indicates a potential replacement need after purchase, but overall review evidence is limited.
What buyers think
Buyer-review evidence is mixed but generally points to solid build and functioning once the batteries are correctly matched to the charger. Several shoppers describe the batteries as good quality and note the charger working reliably with clear charging indicators. A recurring theme is that the charger setup is straightforward and the kit stays organized thanks to the storage design. Evidence also includes isolated issues where a replacement battery was sent after contacting the seller, though broader reliability patterns are not fully established from the available reviews.
What this battery and charger set is for
This kit is aimed at replacing disposable AA and AAA batteries in devices that run better with stable 1.5V output, including remotes, game controllers, toys, cameras, and other everyday electronics. The included charger/storage box is designed so you can recharge batteries quickly and keep spares organized in one place, which is especially useful if you routinely swap batteries across multiple rooms or devices.
Key features and specs that matter
1.5V stable output for AA/AAA devices
The batteries are designed to maintain a stable 1.5V output from full charge through discharge. That matters most for devices that become sluggish when the voltage sags, such as higher-drain electronics.
High capacity lithium cells and the “no power drop” goal
Included cells are listed as higher-capacity lithium batteries: 4 AA batteries rated at 3600mWh each and 4 AAA batteries rated at 1300mWh each. While real-world runtime depends on your devices, the pitch here is consistent voltage and longer practical runtime compared to standard disposable batteries.
Charging case, USB-C input, and dedicated slots
The charger uses a 5V input and connects with a Type-C (USB-C) cable. It has dedicated positions for AA and AAA, so you cannot freely mix battery sizes in the same slots. There is also an LED indicator system to show charging status.
Charge time expectations (and a practical caveat)
The kit is marketed as capable of charging fully in about 3 hours when using a suitable 5V, 3A adapter (not included).
Safety protection and battery “repair” support
It includes multiple layers of protection for common charging risks (such as overcharge, overvoltage, short circuit, overcurrent, and temperature-related issues). It also references microcurrent repair technology that detects deeply discharged batteries and helps restore them, which is a helpful feature for batteries that have sat unused.
Pros and cons in real buying terms
Best for
- Households that go through AA and AAA batteries in multiple devices, like remotes, kids’ toys, and small electronics.
- Buyers who want a charger/storage solution that keeps batteries organized.
- People looking for stable 1.5V output instead of relying on NiMH-style voltage behavior.
- Anyone who has higher-drain devices such as controllers or cameras and wants consistent performance.
Better to consider alternatives if
- You are specifically chasing the fastest possible charge times and need it to match the marketing claim under all conditions.
- Your priority is a charger with fully interchangeable slots, since this case is size-specific.
- You do not already have a compatible 5V power adapter (the charger requires one to operate as intended).
Verdict: is it worth it?
Choose this pemacom kit if you want an all-in-one rechargeable AA and AAA lithium setup, with a dedicated charger/storage case and a design focused on stable 1.5V output. It looks particularly practical for busy households that cycle batteries across many devices. The best reason to buy is convenience plus consistent-voltage design, but set expectations for charging speed, since review evidence suggests it may be slower than the headline claim depending on the setup.
FAQ
Does this charger work for both AA and AAA batteries?
Yes. The charger/storage case is built with dedicated positions for AA and dedicated positions for AAA, so you should place each battery size into its matching slot.
What power adapter do I need for charging?
The charging case requires a 5V power adapter (not included). The faster charge claim assumes using a suitable 5V 3A power adapter.
Is the output really 1.5V the whole time?
The batteries are designed for stable 1.5V output from full charge to discharge, which is intended to reduce “power drop” behavior that can happen with some battery types.
How fast does it charge?
The kit is marketed to charge in about 3 hours under the right power conditions, but real-world charging speed can vary. Some buyers report it may be slower than expected.
What devices are these batteries good for?
They are intended for common AA and AAA devices such as remotes, smart locks, game controllers, toys, cameras, and other everyday electronics, including higher-drain devices where stable voltage is helpful.
Are these lithium batteries safe to charge in the included case?
The charger includes multiple safety protections for charging scenarios like overcharge, short circuit, overcurrent, and temperature-related protection, plus an LED indicator for status.
