Anker PowerCore Speed 10000 QC Review


The Anker PowerCore Speed 10000 QC is an incredible accessory for anyone who needs to recharge their mobile phones on the go. I do a lot of traveling for work and I've been very pleased with the performance of the PowerCore . No more searching for outlets at airports, or sitting on the ground next to the janitor's closet or bathroom waiting to top off my cell phone battery.

Not only does it support Qualcomm Quick Charge 3.0 technology, but for its size, it packs an amazing amount of battery capacity. I can charge a Samsung S7 Edge from empty to fully-charged at least twice. It will even charge the phone with the screen on, something my last PNY-branded portable charger couldn't do. With the screen off, performance is maximized- in fact, it can charge my phone from 20% to full on a 1 hour flight if I'm not using the phone. That means I can take a nap and when I land, my phone is ready to go again (and so am I). I no longer have to worry if I'll have enough juice to get in contact with my ride.

I kind of touched on size already, but this thing is pretty small. The charger measures a mere 3.9" x 2.4" x 0.9". That makes it smaller in length and width than my phone, but of course it's thicker. It's easy enough to slip it into my pants pocket if I need to carry it on me. I usually tote this around in one of the small side pockets in my Ogio Mastermind laptop backpack

The Anker PowerCore Speed 10000 QC is a great portable charger. It checks all the boxes: it's cheap, it's small, it works as advertised. The one drawback is the amount of time it will take to recharge the PowerCore itself (about 5 hrs, so you'll definitely want to charge it overnight). If you travel a lot, you'll appreciate the quality and strength of this portable charger.

As impressive as the Anker PowerCore Speed 10000 QC is, it's not perfect. The most notable drawback is the amount of time it takes to recharge the device. I use the micro-USB cable and wall charger that came with my phone to replenish it. It will take about 5 hours to fully recharge the PowerCore. If charging it overnight isn't a deal-breaker, this might be the portable charger for you.

Honestly, that's the only blemish on an otherwise great product.

Here's what I do like. I like the 10,000 mAh battery. This makes the Anker PowerCore Speed 10000 QC a beast. You definitely won't be disappointed with the battery this portable charger is packing.

I like the fact that the PowerCore automatically turns itself on and off. When you connect your device, it turns on. When you remove it, it turns off. That means there's no on/off button to mess with. The power button on my old portable charger was designed to keep it from turning on in a bag. The rigid, flush-mount button made it hard to press and it usually took more than one attempt to turn it on. This is one less hassle to deal with. Win!

I like that it can charge any mobile device- tablet, phone, Fitbit, etc. If the device has a USB cable with a rectangular male USB Type-A connector, it can be charged. This is the majority of mobile phones on the market. Even with the rise of the newer USB Type-C standard, I think this charger will continue to be relevant as there are only a few high-end phones using Type-C connectors. You can always use a cheap Type-C to Type-A adapter if you need one.

I like the built-in intelligent charging features. The Powercore has short circuit, overcharging, and overheating protection that protect both the portable charger and the device being charged. An extra bit of safety is always welcome when talking about lithium batteries.

Real-World Performance

To test the expected performance of the Anker PowerCore Speed 10000 QC, I performed a complete drain test using both an Amazon Fire HD 8 tablet and a Samsung S7 Edge phone.

Here’s how I did it:

  • Initial conditions. PowerCore is fully charged. The test device’s battery is completely dead.
  • Methodology. The test device is connected to the PowerCore until it’s fully charged. When 100% battery indication is reached, the test device is disconnected and the test device’s battery is allowed to completely drain. The PowerCore’s battery is not recharged. The test is repeated until the PowerCore’s battery is fully depleted.
  • Test devices. The Amazon Fire automatically turns itself on when it’s connected to a power source. The S7 Edge was manually powered on at 2% battery level. Both devices were tested powered on with the screen off. The S7 Edge has an always-on display, so battery levels were taken without turning the display on. The Fire tablet was periodically turned on to get the battery levels. For both devices, WiFi and Bluetooth were turned on, while data and location services off.

Additionally, I documented the PowerCore’s battery indication as each test progressed. The indicator has 4 blue LEDs. The LEDs go out as the battery level depletes.

As you can see from the results, Anker’s performance claims are legit:

Amazon Fire HD 8 Tablet

4750 mAh battery

  • 1st Run- Tablet charged to 100% in 4 hours 56 minutes, PowerCore battery remaining •••
  • 2nd Run- Tablet charged to 51% in 2 hours 32 minutes. PowerCore battery fully discharged.
  • Total- 1.51 charges (7172.5 mAh) in 7 hours 28 minutes.

Samsung S7 Edge Phone

3600 mAh battery

  • 1st Run- Phone charged to 100% in 1 hour 29 minutes, PowerCore battery remaining •••
  • 2nd Run- Phone charged to 100% in 1 hour 24 minutes. PowerCore battery remaining
  • 3rd Run- Phone charged to 11% in 8 minutes. PowerCore battery fully discharged.
  • Total- 2.11 charges (7596 mAh) in 3 hours 1 minute.


If you’re a frequent-flyer, it’s possible the Anker PowerCore Speed 10000 QC could be your new best friend. After 6 months of use, mine is still going as strong as ever. Anker delivers a high-capacity battery in a small package that’s about the size of your palm. This is a quality product that holds up well to the mild abuses that come along with traveling. With Qualcomm Quick Charge 3.0 technology, it charges your devices fast. If you’re in the market for a travel-friendly USB charger, you’ll probably love Anker’s PowerCore lineup.
