With battery overcharge protection built-in to smartphones nowadays phones are really smart! As long as you use a good quality charger like the Anker PowerPort 4 Lite you can charge multiple devices completely safe and keep them plugged in for extended periods of time.

Putting a spin on the traditional Bluetooth speaker, the Soundcore Flare+ and the Soundcore Flare by Anker are eye-catching 360 degree Bluetooth speakers with a ring led light on their base that creates a super cool light show that syncs to the audio being played!
The Anker Soundcore Flare has a unique design reminiscent of a cooling tower, but instead of rejecting waste heat to the atmosphere, the Soundcore Flare surrounds you with room-filling sound waves.
The exterior of the Soundcore Flare has the same cloth material as the Motion Q speaker, surrounding the speaker sides and rubber on the top and bottom, making the speaker suitable for outdoors.
In fact, the Flare speaker has an IPX7 waterproof rating so you can actually submerged it in 1 meter (3.3 feet) for up to 30 minutes.
Wireless connectivity is via Bluetooth 4.2 with EDR integration which makes Bluetooth sound better than regular Bluetooth. The signal coverage is also over a longer range (20+meters in direct line of sight).
Input charge is 5V 2A so the Anker Soundcore Flare charges the 4400mAh internal rechargeable lithium-ion battery in just 3.5 hours. At 12 hours of playtime at 75% volume, battery power is long lasting. While charging the unit, you will see the led show solid red and turn off completely after full charge is complete. Slow flashing red led indicates low battery.
You get a total of six buttons, four on top of the Soundcore Flare and two buttons on the side of it. The buttons on top include two dedicated volume buttons, a light effects button and a "BassUp" button which increases the bass at any volume.
The buttons on the side of the Soundcore Flare speaker are the Bluetooth button and the power button, both of which integrate an led activity indicator.
These two buttons are located just above the micro USB port and 3.5mm audio port which are protected by a rubber flap.

The bluetooth button flashes white when in bluetooth pairing mode and turns solid white when connected to a device.
The Soundcore Flare has an additional feature, called "True Wireless Stereo Pairing Mode", that lets you hook it up to another Soundcore Flare for true wireless stereo. To enter "True Wireless Stereo Pairing Mode", simply hold down the bluetooth button for 3 seconds.

Speakers with a multi-speaker sync feature are pretty neat because they let you get a true left-right stereo sound. The Flare even has a feature called "Boost Up mode" which doubles the volume sound. The integration of fully synced lights to the beat of the music makes the Soundcore Flare even more appealing.

The Anker Soundcore Flare 360 degree bluetooth speaker comes in blue color, as well as a companion app for iOS and Android, called Soundcore App, which lets you customize equalizer settings and the led lights.

Small but mighty, the Anker A2633 PowerPort 3 Nano 20 watt charger is designed for power hungry users, specially Apple customers who own the new iPhone 12, which ships with no brick charger! The low profile footprint of PowerPort 3 Nano is not only convenient when traveling light but, it's also handy if you have narrow access to main sockets. The front of the PowerPort 3 Nano has a glossy bubble finish with the word Anker etched inside it. The rest of the plug is made of matte hard plastic.
Being a wall charger, the Anker A2633 PowerPort 3 Nano works with most electronics, specially ones that support fast charge. It will charge a Nintendo Switch but does not support Charge-and-Play in TV mode; hence you cannot charge a Nintendo Switch in docked mode while playing on a TV. This is due to the Nintendo Switch charging protocol (5V at 2A/ 2.5A/3A).
The Nintendo Switch is sensitive to unexpected voltage changes, which can brick the Switch. The safest way to prevent bricking the Switch is by using the original 15V Nintendo Switch charger. If you prefer to use a third party option, you should get a 56k Ohm resistor USB cable (i.e. Powerline Plus)or use an intelligent powerbank like the PowerCore+ 26800 PD to prevent current overdraw.
The Anker A2633 PowerPort 3 Nano is able to pack that much power in such a small plug, thanks to using the new GaN (Gallium Nitride) technology, which can be found in other wall chargers such as the PowerPort Atom PD 1. The PowerPort Atom PD 1 is capable of 30W but it's twice the size, making the Anker A2633 PowerPort 3 a small powerhouse. There is also the 18W PowerPort 3 Nano (9V/2A) version (model A2616), which came out a few months ago in June and, it's still being sold.
The upgraded 20W PowerPort 3 Nano charger power bump makes it around 10% faster than the 18W charger, which translates to only 3-5 minutes faster charging time. Other than that, both chargers have the same non-folding pin design, which means no moving parts but, it also means no US plug support like you get with the PowerPort 4 Lite charger.
The Nano 20W charger also integrates PowerIQ 3.0 (PIQ 3.0), which is Anker's proprietary fast charging technology that combines USB PD and PowerIQ 2.0 into a single USB-C port. It works a bit like Quick Charge 3.0; hence you can use the PowerPort 3 Nano 20W charger with devices that support Quick Charge, Samsung Adaptive Fast Charging, and Motorola TurboPower.
The Anker PowerPort 3 Nano 20W charger is also compatible with Anker's USB-C wireless chargers such as the PowerWave. The 20W Nano charger also supports 5V/3A (15W) for fast charging devices that only use the 5V protocol. For standard, non-fast charging devices (i.e. 5V/1A) the 20W Nano charger will also work.
Safety-wise, the PowerPort 3 Nano 20W charger does not automatically shut off when it reaches 100% but, it's equipped with overcharging protection and temperature control, which sends the charger into standby mode, consuming very little power.
Compared to the 20W Apple charger, Anker's Nano 20W charger does the same thing, although it does not trigger the "ding" sound alert when charging iPhones. Anker's Nano 20W charger can maintain charge in a mac-book, iPad 12.9 and Samsung's Note 10 / Note 10+ smartphones. 
The Nano 20W charger has a maximum output of 9V/2.2A; hence it cannot charge the Note 10 / Note 10+ at full fast charging speed though, due to these phones requiring a 45W charger. You can buy the Anker PowerPort 3 Nano 20W charger from amazon. There is no cable included so, you will need to have a USB-C to USB-C cable or USB-C to Lightning cable (for iPhones).

Whether dry land or wetland, you can take the SoundCore Sport XL to the beach, a swimming pool, jacuzzi hot tub and even water rafting without worrying about sand, dust and water spoiling it!
The Anker SoundCore Sport XL is solidly built like a tank so it can withstand the elements and pretty much anything that you throw at it thanks to its durable and fully waterproof construction.
Size wise, the SoundCore Sport XL Submersible Bluetooth Speaker is middle of the road between the SoundCore Boost, Soundcore Motion B and SoundCore 2 but it comes with rugged rubber housing and IPX7 waterproofing that lets you submerge the SoundCore Sport XL in water up to one meter deep.
As far as user controls, the Anker SoundCore Sport XL has a total of five buttons on top of the speaker, as well as four small LEDs with the top LED being the activity LED to indicate Bluetooth mode (wireless audio) and wired mode (wired audio).
The play button plays/pauses audio, answers/rejects calls, activates voice control assistant and skips audio forward (there is no skip back function). The volume buttons are dedicated buttons for turning the volume up and down.
The call handling feature in the SoundCore Sport XL is pretty good as it lets you also put a current call on hold (press play button once) and switch between held call and active call (hold down play button for 2 seconds).
When initiating Bluetooth pairing mode, the LED will flash blue rapidly and turn solid blue when connected to a device.
When connecting the SoundCore Sport XL to an external audio source for wired playback the activity indicator LED will flash blue rapidly constantly. The audio playback is then control from whichever audio source you connect the SoundCore Sport XL speaker to.
If you don't have a 3.5 mm audio cable laying around or need a longer audio cable, you can get a very long, quality 3.5mm audio cable from Anker.
The other three LEDs below the activity indicator LED indicate the battery level. Three solid white LEDS indicates battery charge between 65% and 100%. Two solid white LEDs indicate battery level between 35% and 65%. One solid white LED indicates battery level between 5% and 35%. If all three LEDs are off that means battery level is less than 5%.
Aside from the SoundCore Sport XL inside the box, you get also a micro USB charging cable, a layard and user guide.
