Mophie's PowerStation Plus has a fabric finish and houses a 6,mAh battery, as well as an integrated Lightning connector. With the USB-out port, you can charge or recharge two devices at once. The XL can be fully charged wirelessly on a wireless charging pad while the standard PowerStation Plus doesn't have wireless charging.

Note: Ignore Amazon's product description that says the smaller PowerStation Plus has Qi wireless charging -- it's not a wireless charger. Read more. There's nothing fancy about this power bank, but it's slim for a 10,mAh power bank, has two USB-A outputs and is dirt cheap. While it's thicker than some of the portable chargers in this roundup, it is one of slimmest 10,mAh portable chargers and has a USB-C input for charging the battery, but no USB-C output.

No cables are included. This wall charger has a 6,mAh battery. The Ventev houses a 6,mAh output battery. There's also a USB-out on the wall charger so you can charge or recharge another power bank with an extra cable. This Anker model is basically an oversized wall charger that plugs in like a power adapter with a built-in 5,mAh output battery.

The wall charger has got two standard USB charging ports for charging up multiple devices such as your phone and a secondary device or two phones simultaneously, and a little LED indicator on the side lets you check the charge level at the press of a button. These are designed to fit on a keychain and are about the size of an electronic car key. But be warned, they won't fully charge your phone. The idea is to have them around for charging in case your phone dies and you need a spot of juice to get you through a few hours.

Both Atom XS models have an integrated Lightning connector and won't weigh your phone down while charging. But again, this all about the convenience of having a tiny battery charger for emergency charging purposes. Available in a variety of capacities, MyCharge's Adventure series battery packs are designed to withstand drops and offer both dust and water resistance.

They also include a carabiner so you can clip the battery onto a backpack. It has one USB-out port no charging cable is included while the step-up Adventure Plus has dual USB-out ports to charge or recharge two phones at the same time. That's a lot of ports.

So if you need AAA batteries, we think your best best is to get whichever of these three good options is the cheapest. In our testing, we measured an average capacity of mAh for the AmazonBasics AAA batteries, which have a capacity rating of mAh. Along with the Energizer Recharge Universal AAAs—which have a capacity rating of mAh and, based on our testing, an average capacity of mAh—these two brands provided a hair more capacity than rated for.

But the range between all three is still too small to worry about and could easily be attributed to temperature and manufacturing age. And after 50 cycles, all three brands performed about as well as they did on their first charge.

On paper, the EBL AAAs were a clear favorite, but we have some external concerns about reliability that we explain in the Competition section. In our real-world tests, the AmazonBasics AAAs kept a flameless candle flickering for two days and nights 48 hours and kept a remote-control car racing for a full workday eight hours.

Similarly, the Energizer Recharge Universal AAAs kept a flameless candle and remote-control car running for 36 hours and seven hours, respectively. Last, the Panasonic Eneloop AAAs were able to keep a candle going for 36 hours and a car running for 6. For past versions of this guide, we talked to David Hobby of Strobist about the demanding battery needs of professional photographers, and Isidor Buchmann of Cadex Electronics about the mechanics and history of rechargeable batteries.

We also consulted with Lee Johnson, a former NASA electrical engineer, when the technical questions got too technical. Most electronics these days, like your smartphone, have a built-in battery that recharges from a wall charger. But plenty of devices still rely on AA or AAA batteries, such as instant cameras , flashlights , flameless candles , wireless mice , and keyboards , vibrators , electric pepper mills , and more. Fortunately, the technology has made great strides since then.

NiMH rechargeable batteries hold a charge longer, can be recharged more times over their life spans, and have higher capacities than those made with NiCd. In addition to technological upgrades, the price of rechargeables has come down considerably. Even after including the cost of a charger , rechargeable batteries will pay for themselves in five to six recharge cycles compared with buying most brand-name disposables.

And the benefits go beyond your wallet: According to a report from the California Department of Resources Recycling and Recovery , about 4 billion disposable batteries are shipped to the US each year. That means the average US household burns through about 47 batteries per year. But you could buy just 12 rechargeable batteries every four years the average life span of some popular rechargeable batteries instead of the disposables you would otherwise need. There are just a few instances where disposable batteries might be preferable to rechargeables.

Also, electronics that constantly draw low amounts of power—such as some wall clocks, headlamps, or bike lights—work better with disposable batteries. From there, we whittled down our list based on the following criteria:. We performed a mix of technical and real-world tests to see how major brands of batteries performed in a variety of situations. To test the batteries' average capacity, we used a Powerex MH-C rechargeable-battery analyzer to drain them down completely, and then charge them completely, three times in a row.

We charged the AA batteries at mA and discharged them at 1, mA, which is the recommended rate for batteries of this capacity. For AAA batteries, which have less capacity and should be charged and discharged more slowly, we charged and recharged at mA. We recorded the capacity in mAh measured by the Powerex after each of these cycles and calculated the average capacities.

We always prefer having built-in cables over supplying and transporting our own cables, which take up extra space, get tangled, and are easily misplaced. If you want the fastest possible charge and the highest capacity of any power bank we tested—and can bear to carry around a separate charging cable or two—this is a great option.

Rather than having a wall charger that you leave at home and a separate power bank that you carry, you can rely on a single gadget that does double duty. The PowerCore Fusion is a relatively small portable charger—about the size of a standard tape measure —and you can easily stow it in an accessories pouch or a large pocket. Its rated capacity 5, mAh—enough for a bit less than two full iPhone XS charges is similar to that of the Jackery Bolt.

We know the technology exists, because a pricier Anker model and the discontinued Jackery charger we tested has this capability. The Anker PowerCore 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 PD Redux.

And, like the Redux , it has a hefty 10, 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. 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.

The Flux Charger and Flux Lite are lightweight 3. 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. We also like its sleek shape and dimpled texture.

The intelliArmor Scout Max is a jack of all trades, master of none. 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.

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. The RP-PB 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.

Plus, the ZMI is bigger and heavier than the Anker.
