The shape of a battery is an important factor depending on the device, as space constraints and design needs often dictate which type is best. Part 4. Capacity. The capacity of a 3.0V lithium battery is measured in
To connect a USB device, you''d use a USB extender. Wired versions are available; they convert USB to ethernet cabling to extend the signal range beyond USB''s 5m limit. I don''t know of any wireless extender products, but it''s not impossible. It''d make an interesting DIY project.
This means that the system level battery life will likely be better with an LDO than with a buck converter. But aren''t LDO''s inefficient? Well let''s look at that. What is the efficiency of an LDO? Assuming the quiescent current is low, the efficiency can be simplified to Vout/Vin. The average Vin for a lithium ion battery is 3.7V. 3.3/3.7 = 89%.
So I figured there should be a device that takes QC and outputs USB-PD. After doing some research I found the FL001Super USB multimeter from ChargerLAB that has this functionality. But they''re expensive, over $50, and the company seems to have gone out of business. I found some other similar devices on Ebay and Amazon but they seemed kind of

Has anyone heard of a protocol converter to be able to switch QC 3.0 to PD? QC 3.0 battery packs and solutions seem more widespread, even though PD is the better protocol IMHO.
These batteries have a voltage that goes from 4.2V to 2.7V typically during their discharge cycle. My circuit (running at 3.3V) has a maximum current requirement of 400mA -- although I should state that this is only the peak draw occurring about 5% of the time; the circuit draws only about 5mA the remaining 95% of the time). Question
3.0V lithium batteries have become essential in modern electronics, powering everything from small gadgets to critical devices. Known for their long-lasting performance and reliability, these batteries are widely used due to their high energy density and stable voltage output. But what exactly is a 3.0V lithium battery?
Those "5V output" batteries are a 3.6-ish volt lithium-ion battery with a charging circuit and 3.6-to-5V boost-converter. You could cut out some complexity by connecting a 3.6-ish volt battery to your 3.0-ish volt device. Several (all right: two, on reddit) people claim to have done this.
Surely 3 AA batteries will normally give you a nominal 4.5V and quite likely you can run your device straight from the USB's 5V without any resistors. But we would need more information. What is the device? How much power does it require?
So, while you can't recharge a typical 3.0V lithium primary battery, you can use a 3.7V lithium-ion rechargeable battery for similar applications, depending on the device's voltage requirements. Part 6. How long does a 3 volt lithium battery last?
Background I wish to power my circuit with a Lithium-ion or LiPo battery (likely a battery with around 1000 mAh capacity). These batteries have a voltage that goes from 4.2V to 2.7V typically during their discharge cycle.
