Charger USBs, also known as USB wall chargers or USB power adapters, are essential accessories for charging various electronic devices, including smartphones, tablets, cameras, and more. They typically consist of a wall plug with one or more USB ports and are used to convert electrical power from a wall outlet into a suitable form for charging devices via USB cables. Here's what you should know about charger USBs:

USB Ports: Charger USBs come with one or more USB ports, allowing you to connect your device's USB cable for charging. They can have a single USB port or multiple ports, making it possible to charge multiple devices simultaneously.
Output Power: Charger USBs have different output power ratings, typically measured in watts (W) or amperes (A). Higher output power can charge devices faster, but it should be within the safe range recommended for your device to avoid damage.
Compatibility: Charger USBs are compatible with a wide range of devices that use USB charging, including smartphones, tablets, e-readers, digital cameras, and more. Ensure that the charger USB you choose is compatible with your specific devices.
Fast Charging: Some charger USBs support fast charging technologies, such as Qualcomm Quick Charge or USB Power Delivery (PD). These technologies can significantly reduce charging times for compatible devices.
Compact Design: Charger USBs are often designed to be compact and portable, making them convenient for travel or everyday use. Some may also have foldable prongs for added portability.
Safety Features: High-quality charger USBs include safety features like overcurrent protection, overvoltage protection, and short-circuit protection to safeguard your devices from damage due to electrical issues.
Brand and Quality: Consider purchasing charger USBs from reputable brands or manufacturers known for producing reliable and safe charging accessories. Cheap, low-quality chargers may pose risks to your devices.
Multi-Port Chargers: If you have multiple devices to charge, you can opt for charger USBs with multiple ports, allowing you to charge several devices at once without needing multiple adapters.
Compatibility with USB Cables: Ensure that your USB cables are compatible with the charger USB's port type (e.g., USB-A, USB-C) to establish a secure connection for charging.
Voltage and Plug Type: Be mindful of the charger USB's voltage compatibility with the regions you intend to use it in, and ensure it has the appropriate plug type (e.g., Type A, Type C) for your wall outlets.

Charger USBs are versatile accessories that can make your charging setup more convenient, whether you're at home, in the office, or on the go.When selecting a charger USB, consider your device's charging requirements and any specific features you may need, such as fast charging or multiple ports, to ensure that your devices are charged efficiently and safely.

User questions & answers

Question:	Will this work for flexvolt 60v batteries
Answer:	I can't find anything that specifically says so, but I'm 98% sure that it will. One of the main features of the FlexVolt battery is that it changes voltage when you change tools. Since the FlexVolt battery is backwards compatible to the 20V Max tools and chargers, I can't think of a reason why it wouldn't work. In other words, anything you can attach a 20V Max battery to, you can also attach a FlexVolt. Good luck.
Question:	I have tried it with my Samsung Note 10.1, and it will not charge. Is there compatibility with tablets like this
Answer:	Wow. So um, yeah, this was an outdated design in 2013. It's now almost 2019. DeWalt's not really in touch with their customers... they put something out and assume technology doesn't change? (It's OK, I get it... it's a closed ecosystem with proprietary batteries... customers will accept whatever they're offered, since there's no competition). NOTE: A DIY-minded individual could do this: get a cigarette lighter socket (salvage, or $10). Connect those leads to this battery. Pop in a USB car charger of any size you like ($10, and they're made to handle voltages up to ~18-20V and these batteries don't really output 20V, since they're rounding up those 3.65v cells to 20v and summing the set). All the parts you need are on Amazon!
Question:	With a fully charged 20V Max battery, roughly how many times would I be able to charge my phone before I would need to charge the 20V battery again
Answer:	It depends on which battery pack you plug into it. The easiest way to calculate the actual capability is to work with watt-hours instead of amp-hours. Take the amps and multiply by the volts of the pack.12v 1.5 AH pack = 18 watt-hours20v 4.0 AH pack = 80 watt-hoursAn iPhone 6 battery has 11 watt-hours. Therefore the large pack could charge it seven times from a FULLY discharged state.
Question:	What is the output of the USB ports (amperage
Answer:	According to a DeWalt product manager, The total output is 1.5 amps. If you only plug one device in it will pull up to 1.5 amps. If you plug two devices it will split the power .75 and .75. It is actually the device that determines the amount of power it pulls, so it might not be split right down the middle. If you have a product that wants to pull more, it can, so sometimes it could be .9 and .6.
