HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions
Quick take
This TP4056-style charging board kit from HiLetgo is built for DIY charging of a single 18650 Li-ion cell (1S), using a Type-C USB 5V input and providing charge status via LEDs. Buyers report it works reliably in small battery-powered projects, but the modules are very small and may need proper mounting and careful setup to fit your enclosure.
Pros and cons
Pros
- Designed for 1S 18650 Li-ion charging, with listed cut-off and protection thresholds (charge termination around 4.2 V range).
- Type-C USB input, recommended 5V input, with maximum charging current output listed at 1000 mA.
- Status LED behavior indicates charging vs full (red for recharging, green for full).
- Sold as a 3-pack, which is helpful when building multiple devices or spares for projects.
Cons
- Small board, and multiple buyers note mounting holes are not included, so you may need a custom case or method to keep it secure.
- Best suited to DIY wiring and battery projects, not as a finished charger for consumer-style use.
What buyers think
Buyer-review evidence is limited in detail, but the comments that are present generally point to dependable charging performance in DIY electronics. Several buyers describe successful use powering or charging 3.7 V-class 18650 projects, including an ESP32 setup and a battery-based device build. Review themes also include that the module can meet expected behavior when wired correctly and that the small size affects how easily it can be installed, with some buyers wishing for mounting holes.
What this charger module is for
The HiLetgo TP4056 USB charger boards are made for one-cell lithium-ion charging (a single 18650). If your project needs to recharge a 3.7 V nominal battery from a USB 5V source, this style of module is a common choice for compact electronics, prototypes, and enclosure-based builds.
Key specs that matter for buying
- Input: Type-C USB with an input voltage range listed as 4.35 V to 6 V (recommended 5 V).
- Charging current: Maximum charging current output listed at 1000 mA (1 A class).
- Charge cut-off / thresholds: Charge cut-off voltage listed around 4.2 V (±1%), with overcharge lift voltage and overcharge protection voltage also listed (for protection behavior).
- Low-voltage protection: Battery discharge termination voltage listed (protection behavior below a cutoff).
- Status LED: No-load LED behavior and color indication listed, with red for recharging and green for full.
Pros and cons in real-world build terms
Where it fits well
- DIY devices with a single 18650 cell: If you are building a small power system, the 1S focus and USB input are directly aligned.
- Projects that benefit from a small module count: Buying a 3-pack can be practical if you are prototyping multiple devices or want spares.
- Users who want visible charge state: The red/green LED behavior can help during setup and troubleshooting.
Where you may need to plan ahead
- Not a “finished charger”: This is a charging board for projects, so it requires appropriate wiring, battery contacts, and basic build integration.
Price and availability
The kit is positioned as an inexpensive, small-quantity option, and it is listed as in stock. If you are comparing options, focus less on brand and more on whether the module matches your exact battery type (1S Li-ion 18650) and your desired input power (USB 5V).
Is it worth it?
The HiLetgo 3-pack can be a solid value if you are building (or repairing) small electronics that need USB-powered charging for a single 18650 cell. It appears to perform as expected in DIY projects, and the LED status can make it easier to verify charging state. The main tradeoff is practical, not theoretical: you may need to build your own mounting solution and ensure your USB power setup triggers charging properly.
FAQ
Does this module work with a single 18650 cell?
Yes. It is intended for 1S 18650 (3.7 V-class) lithium-ion charging, using the module’s listed cut-off and protection thresholds.
What input does it use?
It uses a Type-C USB input. The recommended input voltage is listed as 5V, with an input voltage range listed from about 4.35 V to 6 V.
How much charging current does it provide?
The maximum charging current output is listed as 1000 mA (1A class).
What do the LEDs indicate?
The LED behavior is listed as red for recharging and green when the battery is full.
Is it easy to install in a project enclosure?
Installation may require planning. The board is small, and some buyers note that mounting holes are not included, which can mean you need a custom case or secure method to keep it in place.
Will it work with any USB-C charger?
It should work when the charger provides the expected voltage (recommended 5V), but USB-C setups can vary. If charging does not start, check that your USB-C power source and connection meet the module’s input expectations.
