Full Review

There are so many power banks in the market that it’s sometimes easy to forget they’re all built differently. Look a bit closer, though, and you’ll begin to see the nuances. Take, for example, size and capacity. For a given capacity, each model from each brand can differ wildly in size. Because the truth is, size and capacity are two different things, and it’s up to brands how to balance the two while keeping other features in mind.

In this review, we’re looking at a very good example of how this works out. Specifically, how a power bank can be so small and lightweight while packing so much capacity.

NITECORE’s NB10000 doesn’t look too impressive right out of the gate. It has two ports, a power button, and a slim carbon fiber body. You’d be forgiven for thinking that this power bank is only 6,000 or 7,000 mAh. It’s actually a 10,000 mAh unit, however, and at just 150 g, it’s one of the densest power banks we’ve tested, at the cost of the extra frills found with some other power banks.

The Rundown

We’ll start with a tour of the hardware features around the outside. Up at the top are two USB ports—one USB-A and one USB-C—and a physical power button with embedded LED indicators. There are four LED indicators in total, with the one on the far right indicating when it’s in low current mode, while the rest indicate charge status. It’s a pretty basic setup, visually speaking, but the NB10000’s updated version 2 does have yellow accent coloring around the ports.

Reading the LEDs can be somewhat confusing since they are all located on one side of the button, and only three of them indicate charge level. We sometimes get the wrong impression that the unit is only half-full since three LEDs only span half the length of the button. It’s not, though, and we had to get used to this odd design choice to avoid overcharging the unit. You can also double-tap the button to turn off the LEDs altogether.

The good news is that NITECORE’s moved the LEDs beside the power button on the newer version of the NB10000. It’s now much easier to read, and we wish it came out this way in the first place.

Charging the NB10000 is done through the USB-C port. This port supports two-way USB Power Delivery (18W input and 20W output on the newest version). Meanwhile, the USB-A port only supports 18W output. Both ports, however, support Quick Charge 3.0. If you decide to use both ports simultaneously, the output is capped at 15W (5V3A). You can also charge the NB10000 while using it to charge another device. All in all, it’s a fair amount of charging functionality for a power bank of this size.

As for the low current mode, that’s designed for low current devices like smartwatches and wireless headphones—devices that generally don’t require a ton of power. To activate, simply tap and hold the power button.

As the name suggests, the NB10000 has a mAh rating of about 10,000. Doing some rough back-of-a-napkin math, that’s worth about three charges for either a Samsung Galaxy S22 (3,700 mAh) or Apple iPhone 13 Pro (3,095 mAh). If you’re toting a higher-end device, that’s two charges for a Galaxy S22 (4,500 mAh) or iPhone 13 Pro Max (4,352 mAh).

Your mileage may vary since power transfer isn’t a hundred percent efficient in the real world, but you can get quite close. NITECORE is quite conservative in their own estimates, only quoting two charges for an iPhone 13 Pro and 1.5 charges for a Huawei P50 (4,100 mAh).

Packability

The most impressive feature of the NB10000 has to be its size. We’ve seen plenty of power banks smaller than this, but none really match it in terms of power density. We’ll get to the comparisons later. For now, see how it packs easily into our tech pouch.

It’s an easy fit even for an already-packed tech pouch such as ours. The only problem is how the NB10000 is shaped: it’s a very boxy power bank. Its corners are relatively sharp, and they can catch on soft fabrics or loose threads. Think of stretchy mesh typically found in tech pouches, loose shirts, and worn-out pants s—these will probably snag on the NB10000 sooner or later.

On the other hand, we like that NITECORE pretty much went as minimal as possible with the NB10000’s design. There are no frills like a curvy chassis or shiny trim added solely for the sake of styling. Yes, the body is carbon fiber, but that’s as much about keeping the weight down as it is about the looks. Plus, it is IPX5 rated, so it also has good water resistance.

For the record, we’re not quite fond of how the carbon fiber finish looks, but it is what it is.

Quick Comparison

Now’s the part where we actually see how the NB10000 stacks up against the competition. We’ve gathered two power banks with a size or capacity, namely the Anker PowerCore Lite 10000 mAh and the Satechi Quatro Wireless Power Bank. We’ve also thrown in the Futurizta Tech Pixy Mini, one of our go-to power banks due to its exceptionally compact size.

custom, power, banks, bank

NITECORE NB10000: 10,000 mAh / 150 g = 66.7 mAh/g Futurizta Tech Pixy Mini: 5,000 mAh / 98 g = 51.0 mAh/g Anker PowerCore Lite 10000mAh: 10,000 mAh / 216 g = 46.3 mAh/g Satechi Quatro Wireless Power Bank: 10,000 mAh / 268 g = 37.3 mAh/g

The figures speak for themselves, with the NB10000 being the clear winner in terms of sheer power density. Of course, the other battery banks have their merits in extra features the NB10000 doesn’t have. For example, while Satechi’s Quatro may come off as the worst, it also features two wireless charging spots.

Features-wise, the NB10000 does come off a little modest. Save for the low current mode, it doesn’t boast blazing fast wired charging speeds, nor does it have wireless charging. There are no built-in flashlights, nor is there a digital readout. You’ll be hard pressed to find branding even—and that’s okay.

For straight-up packing as much power as you can while minimizing space occupied, the NB10000 is a clear-cut winner in our book. Sure, the sharp corners and carbon fiber finish may be cons, but its charging potential is a compelling selling point for any digital nomad.

Review: Aukey Slim 10,000mAh USB-C Power Bank

Mid-range power banks are amongst the most used types of portable chargers on the market now. The reason for that is because they have enough power to charge our smartphones to full power at least once or twice, and yet they have very small form factors.

The form factor of mid-range power banks is basically that of mini power banks that have 3,000mAh power capacities. In this review, we’re going to be taking a look Aukey’s 10,000mAh Slim USB-C power bank.

The charger has an absurdly small form factor while still making use of mid-range power capacity and it also has a USB-C port for faster standard charging.

Power Capacity:

The charger does have a 10,000mAh power capacity, however, if you don’t yet; the power capacity that brands state with their power banks is just for show. It’s not the actual capacity that you’re going to be receiving.

What you really need to know is the amount of power that you’re actually going to be receiving, also known as the output capacity. Basically, the capacity that you receive after the initial power has gone through its conversion during charging.

3.7 x 10,000 = 37,000 / 5 = 7,000

Most of the time, you’re going to average about 7,000mAh of power that you can actually use from the charger. This is a great amount of power for charging smartphones, as that’s the main type of device that this power bank is made for.

In terms of how many full charges that you’re able to get from this power bank?

About two. Most smartphones these days have a 3,000mAh battery capacity, mainly starting with the Samsung Galaxy S7, then the S8 had a 3,000mAh battery and so did the S9. However, in the recent release of the Galaxy S10, the battery capacity barrier is being breached.

With the S10e now using a 3,100mAh battery, Galaxy S10 now has a 3,400mAh battery and S10 Plus has a whopping 4,100mAh battery.

So if you’ve got an even newer smartphone like the Samsung Galaxy S10 on the market, then you might fair even less than two full charges.

Output Charging:

There are two ports that you can use to charge your devices.

One is the USB-A port that has a 5V/2.4A (12W) charging speed. The other one is a USB-C port that has a 5V/3.0A (15W) charging speed.

So this power bank does not feature Quick Charge and neither does it feature Power Delivery charging with its USB-C port. We thought we’d mention that ASAP before there are any misunderstandings.

The standard port does have standard charging and with 12W, it’s still quite fast.

As for the USB-C port, it’s going to be most useful to use with USB-C Andriod smartphones, as you can charge your smartphone at 15W. Rather than using the slower USB-A port. Just remember, that you’ll need a USB-C to USB-C charging cable to use the USB-C port.

This power bank does not come with a USB-C to C charging cable.

Also, just to clarify why this power bank does not feature Power Delivery, it’s because the USB-C port has a 15W charging speed. While Power Delivery charging starts at 18W.

Another thing to know is that the USB-C port on this power bank is going to be most helpful for charging smartphones only. 15W of charging power from a UBS-C port is not enough power to charge a tablet or laptop.

Input Charging:

To recharge this power bank, you have two options.

You can either use the USB-C port, that can also be used to recharge the power bank. The USB-C port has a 3 Amp recharging speed.

Or you can use the slower Micro-USB input port that has a 2 Amp recharging speed.

Size and Weight:

The length of the power bank is 4.9 inches, a width of 2.7 inches, and a thickness of 0.5 inches. The weight of the power bank is 7 ounces.

In terms of length, the charger is smaller than most smartphones on the market, and with its thinness, you can place this power bank in the same as your smartphone if you wanted to.

Functional Components:

Nearly all of the functional parts of this power bank are on the same side.

The USB-C port, USB-A port, Micro-USB input port, and four green LED power capacity lights can be found on the same side. As for the power button, that can be found on the long length side of this power bank.

Structure and Material:

The build quality of this power bank is pretty good structurally speaking. The ports feel solid to use, and the power button is responsive.

If you were to drop it, the charger could get damaged though. However, it is quite light, and a fall may not do as much damage as a heavier power bank would have.

Tech:

On the tech side, the charger does not overheat, at least in our case.

There have been reports of this power bank actually having its batteries expand and bust out of the casing, and leaving the power bank useless.

In terms of technical improvements, this power bank does have a flaw. It makes use of Lithium Polymer batteries that are more prone to expansion due to heating up. This can be remedied with the usage of Lithium-Ion batteries.

However, that would cause the power bank to be larger and not nearly as small as it is right now. It’s an equivalent change factor in this case. It’s not assured that the batteries would expand as it’s a case by case type of occurrence.

custom, power, banks, bank

Reliability

The reliability of this power bank is going to be best for Android USB-C smartphones owner. Even though the USB-C port does not feature Power Delivery, it’s still more powerful than a standard port.

It’s not reliable for charging USB-C laptops, and not really meant for charging USB-C tablets. Although you might get away with charging tablets with USB-C port as long as it’s a tablet, and not a laptop/tablet hybrid. As 15W of charging power is not enough for those types of larger devices.

Summary:

There’s enough power capacity to charge most smartphones to full power about two times. This power bank is best for charging USB-C smartphones, as the USB-C port is faster than the USB-A port.

The power bank is so small that you can basically place this charger in the same that you place your smartphone in.

There have been reports of this power bank having its battery expand. There’s a chance of that happening as the charger does make use of Polymer batteries, but it’s not assured that it’ll happen. As the power banks that those users had may have had defects.

This power bank is most reliable for Android smartphones that have a USB-C port. As there’s enough power capacity to charge most phones to full power at least twice, and the charger does not.

Specs of the Aukey Slim 10,000mAh USB-C Power Bank:

Initial: 10,000mAh

Output Capacity: 7,00mAh

USB-A Port: 5V/2.4A (12W)

USB-C Port: 5V/3.0A (15W)

USB-C Input: 5V/3.0A

Micro-USB Input: 5V/2.0A

  • LED Power Indicator: 4 Power Indicators
  • Size: 4.9 x 2.7 x 0.5 inches
  • Weight: 7 Ounces

Conclusion:

Aukey’s slim USB-C 10,000mAh power bank has quite a lot going for it with its small form factor, fast standard charging, and an easy to use design. We just hope that its small battery problem doesn’t become a big one.

myCharge MagLock Magnetic Powerbank

Best MagSafe battery pack overall

  • Comprehensive functionality
  • USB-C port
  • Built-in speaker signals charge level and connection
  • Budget-friendly

Features: Capacity: 3,000mAh, 6,000mAh, 9,000mAh | Charging Port: USB-C | Power button: Yes

The latest company to offer a MagSafe compatible battery pack is myCharge with its MagLock lineup. The MagLock lineup has three different options, ranging in capacity and price. A 3,000mAh option is 50, 6,000mAh is 60 and the 9,000mAh pack is 70.

The MagLock has a unique raised design where the pack connects to the phone. According to myCharge, the gap between the phone and the battery pack allows both devices to remain cooler than the competition, which leads to better efficiency and faster charging rates. When you connect the pack to your phone, it plays a short sound to let you know the pack is in use. Another sound plays when you remove the pack from your iPhone.

There’s also a power button, but I haven’t had to use it. I just attach the pack to my phone, let it charge, and then remove it. The MagLock is charged via a USB-C connection, and functions as a wireless charging pad if you place your phone on the pack while it’s plugged in.

Apple MagSafe battery pack

Best MagSafe battery pack for native integration

  • Deep integration with iOS takes full advantage of the battery pack
  • Smart charging ensures proper iPhone and battery pack charging
  • Your iPhone uses reverse wireless charging to charge the pack
  • Compact size

Features: Capacity: 1,460mAh/ 11.13Wh | Charging Port: Lightning | Power button: No

Apple’s MagSafe battery pack is the second smallest battery pack I tested, even though pictures can make it look big. Inside are two battery cells with 11.13 Wh of capacity. Don’t expect the battery pack to charge your iPhone from 0 to 100. Wireless charging is highly inefficient due to several factors (heat being one of them). You’re more likely to get around a 60% charge on the iPhone 12 Pro, and for most, that’s more than good enough to get through a long day at work or when traveling.

At 100, the MagSafe battery pack is the most expensive pack of the lot. Its tight integration can arguably justify Apple tax with iOS 14.7 and above; when you place the pack on a compatible iPhone, you’ll see an animation on your screen letting you know how much of a charge the pack has. It will automatically begin charging your phone. The first time you attach one to your phone, you’ll also see an alert letting you know it will keep your phone at 90% to protect your battery. The battery widget built into iOS will show the pack’s current charge level, right alongside your iPhone and other accessories.

Charging the battery pack is done via a Lightning connector on the bottom of the pack. If you use a 20W adapter, you can charge both the pack and the iPhone at the same time by plugging the connector into your iPhone. Your iPhone will then use reverse wireless charging to top off the battery pack.- the first time we’ve seen such a feature in use from any iPhone model.
