Power Supply for IoT and Low-Current Devices
Many common mobile batteries automatically stop supplying power to devices with low current consumption, such as single-board computers and various IoT devices, as they interpret the low current as a full charge. The cheero Solitta IoT 10000mAh is designed to support continuous power supply to low-current devices. Once the power button is pressed, it maintains output from its USB-A and USB-C ports until the battery is exhausted or the button is pressed again, ensuring stable power delivery. It is important to note that this product is designed for 5V input/output for IoT devices and does not support Power Delivery.
Next-Generation “Semi-Solid-State Battery” for Long-Term Safe Use
Utilizing a new generation of gel-like electrolyte, the semi-solid-state lithium-ion battery exhibits significantly less heat generation and swelling compared to conventional lithium-ion batteries. It also performs robustly in high and low-temperature environments, ensuring stable performance over an extended period. Nail penetration tests did not result in ignition. While semi-solid-state batteries offer higher safety than conventional lithium-ion batteries, this does not guarantee non-ignition in all situations.
Simple Operation
To begin charging, simply connect the cable and press the power button on the battery. To stop, press the power button again. Although designed for IoT devices, it can also function as a standard mobile battery, providing up to 15W of power to smartphones and tablets, with simultaneous charging for up to three devices. Users should remember to turn off the power after use.
Japanese Manufacturer’s Inspection Standards
The product is equipped with automatic stop functions that activate during overcharge, overdischarge, short circuit, and overheating. Rigorous inspections ensure safety. As a PSE-marked product, it complies with the technical standards of the Electrical Appliances and Materials Safety Act.
