The Anker PowerCore 10000 PD was our pick for the power bank with the fastest possible charge until it was discontinued and replaced by the slightly smaller (same width and thickness, but about a half-inch shorter) Anker PowerCore 10000 PD Redux.

The Anker PowerCore+ 10000 fits easily in a pocket—it’s the same width as an iPhone SE, about twice as thick, and just a few millimeters taller. And, like the Redux, it has a hefty 10,000 mAh capacity rating. But it has a low recharge speed compared with other models we tested (just 12 watts), and it offers only USB-C output. We also think its rough texture and less-ergonomic shape (flat on one side, rounded on the other) make it a weak contender.

The Anker PowerCore Fusion Power Delivery is sort of a mashup of our favorite PD wall charger and the PowerCore Fusion 5000. In addition to a USB-A output port, it has a PD output port rated for 30 watts that should allow it to charge a MacBook Pro—something that none of the other two-in-one models we tested can do. But even so, we think its $80 price tag (more than double the cost of the PowerCore Fusion 5000 at this writing) is too steep for its 5,000 mAh capacity.

The EasyAcc 6000mAh Ultra-Slim Power Bank (Lightning) and EasyAcc 6000mAh Ultra-Slim Power Bank (Micro-USB) are lightweight (4 ounces) and as high-capacity (6,000 mAh) as the Jackery Bolt. But we think the Bolt’s smaller size (in terms of height and width) make it easier to hold in your hand and fit into a pocket. Plus, the Bolt has two built-in cables (Micro-USB and Lightning), while these models each offer only one or the other.

The Flux Charger and Flux Lite are lightweight (3.1 ounces) and small enough to fit in a pants pocket. Both have a Micro-USB input port, a USB-A output port, and built-in USB-C and Lightning cables. The only difference between the two, as far as we can tell, is that the Flux Charger comes in either black or white color schemes and the Lite comes in pastel blue, pink, or lavender. However, the cables are nearly impossible to get back into their slots after charging—in contrast to those on the TravelCard Chargers and the Jackery Bolt, which are velvety smooth to slide in and out—and the materials seem flimsier.

The Flux Charger Plus has a higher capacity (10,000 mAh) than the Flux Charger and Flux Lite (both are rated for 4,000 mAh) and the Jackery Bolt (6,000 mAh). In addition to built-in Lightning and USB-C cables, it offers two USB-A output ports and a Micro-USB input port. But it’s not as portable as its smaller brethren, and its built-in cables are similarly sticky.

The HyperJuice USB-C + Lightning Battery (10,000 mAh) combines the best aspects of the Jackery Bolt (dual built-in cables) and the Anker PowerCore 10000 PD Redux (10,000 mAh capacity, top USB-C PD charging speeds). We also like its sleek shape and dimpled texture. However, its lack of a USB-A output port makes it useless for charging many common devices (most wireless headphones, some Android phones, and more), and it’s one of the heaviest models we’ve tested. Plus, at this writing, it’s more expensive than any of our picks.

The intelliArmor Scout Max is a jack of all trades, master of none. It has a built-in AC plug and Micro-USB port to charge itself, and its built-in Lightning, Micro-USB, and USB-C cables can charge pretty much any handheld device. But unsheathing the cables and plug is trickier here than on other models we’ve tested (such as the Jackery Bolt and Anker PowerCore Fusion 5000), and its 10,000 mAh capacity is no better than that of the Anker PowerCore 10000 PD Redux. Plus, we couldn’t find any warranty information on the company’s site and can’t vouch for its customer support.

The Jackery 6700mAh Portable Charger with Dual USB Wall Charger (discontinued) had USB-C and USB-A output, but it measured about a half-inch wider than the PowerCore Fusion 5000. It also offered only AC input, whereas the Fusion 5000 has a Micro-USB input port in addition to AC input.

The Mophie Powerstation Hub has a bit more capacity (6,000 mAh) than the PowerCore Fusion 5000, plus it adds a USB-C PD input/output port and Qi wireless charging. But we don’t think those features justify the current $100 price tag. Plus, representatives from Mophie told us that the company was issuing a voluntary recall of the international adapters that came with the Powerstation Hub following reports that the prongs could break off inside a wall outlet and cause an electrocution hazard.

The Mophie Powerstation Plus Mini has an adapter that lets you turn the built-in Micro-USB cable into a built-in Lightning cable, which is a nice idea, but sliding it on and off is not super smooth. The adapter also seems likely to vanish since it’s not tethered to anything. And without that adapter, the power bank is nearly worthless: You lose the Lightning-output function altogether, and the Micro-USB cable still works but doesn’t stay firmly in its slot.

The Mophie Powerstation Plus (USB-C) and Mophie Powerstation Plus Mini (USB-C) are sleek-looking and lightweight. But their built-in USB-C cables are especially tricky to get back into their slots, which we think would drive most people up the wall. And both are much bigger and heavier than the TravelCard Charger (USB-C), which solely offers USB-C output.

The RAVPower PD Pioneer RP-PB186 is nearly identical to the Anker PowerCore 10000 PD Redux, but we just barely prefer the Redux. The RP-PB186 has rough ridges at each of its seams that make it less comfortable to hold. But if you find it for significantly less than the Anker model, it would be a great alternative.

The RAVPower PD Pioneer RP-PB172 offers a wide range of input options, including Lightning, Micro-USB, and USB-C PD, but only the last will recharge the power bank at top speed. And aside from the PD port, it has only one USB-A output port. We think you’re better off spending a little more for one of our high-capacity power bank picks, all of which offer plenty of output options, have hub functionality (you can pass power and data through them), and are powerful enough to charge most laptops.

The Tronsmart Trim 10000mAh USB-C Power Bank and the Aukey PB-Y13 have the same capacity (10,000 mAh) as the Anker PowerCore 10000 PD Redux, and unlike that Anker model, they both provide Micro-USB input and Quick Charge 3.0 output. But we don’t think either feature offers a huge benefit to most people. Also, judging by our past experience with all three brands, we think the C-to-C cable that comes with the Anker model is a better value than the Aukey A-to-C cable or the Tronsmart Micro-USB cable.

The Xcentz 5,000 mAh and 10,000 mAh Portable Chargers are most comparable to the Anker PowerCore 10000 PD Redux—they’re lightweight (less than half a pound each) and roughly the size of a candy bar, and they offer USB-A and USB-C PD output ports. But the rounded edges of the Redux and that model’s narrower shape make it more comfortable to hold or pocket, and they also give it a slightly more pleasing aesthetic.

The ZMI PowerPack Ambi 10K Dual USB-C Power Bank has the same capacity rating as the Anker PowerCore 10000 PD Redux, as well as two fast-charging USB-C PD ports. However, unlike that Anker model, the ZMI has no USB-A output ports, which most people like to have, and its combined output rating (20 W) is lower than what we measured from the Anker (18.8 W and 10.8 W, or almost 30 W total). Plus, the ZMI is bigger and heavier than the Anker.
