Eco-friendly designs, but high prices for such low specs

Eco-friendly designs, but high prices for such low specs

Mophie is well-known for each the standard of its merchandise and the hefty price ticket hooked up to them, so we have been once we heard that a handful of its staff had splintered off to start out a brand new, eco-mindful energy accent firm referred to as Nimble. With shopper cost-cutting recyclable packaging and a give attention to renewable supplies, we have been curious to see if Nimble might disrupt the battery and charger established order — a extremely aggressive market. Sadly, Nimble’s specs and prices simply cannot beat the competitors. 

We reviewed each Nimble’s in depth assortment of batteries and its wi-fi charging equipment — a way more fascinating topic now that Google has bequeathed the Pixels with Qi. Sadly, for all of us, we discovered Nimble’s batteries to hold a premium in worth that wasn’t supported by product efficiency. Though generally we have been impressed with the fashion and common construct high quality, in addition to the idea of lowered environmental impression, these batteries and wi-fi chargers are a troublesome promote on look alone.

Reviewed by Richard Gao and Ryne Hager.


Nimble gives batteries/moveable chargers (a reputation I hate) in 4 sizes named by the variety of additional days they supply the typical telephone. At $50-$100, they’re additionally fairly steeply priced. With a mere 18W output over USB-C, Nimble’s batteries do not examine too favorably to different main OEMs on the similar worth, or the multitudes of random Chinese language manufacturers on Amazon. Whereas I dig the general construct high quality and aesthetic, I do not assume Nimble’s batteries are value it on the MSRP — although we do have an unique coupon ( DROID15 ) that will get you an additional 15% off at Nimble’s website.

Design, hardware, what’s within the field

All of the Nimble batteries, from smallest to largest by capability.

The product schtick for Nimble could also be eco-mindful reuse of supplies, but it does not appear to compromise the construct high quality of its merchandise. The shell is product of aluminum and a metallic-flecked semi-transparent darkish plastic with a soft-touch end. Nimble is fast to level out the interior plastics are of plant-based origin, but no point out of recycled or pure supplies is included with regards to the TPE a part of the physique. That is too dangerous, as I might have loved seeing how a extra eco-friendly shell may need appeared, since all the recycled plastic merchandise I’ve used have a pleasing matte texture that I actually take pleasure in.

Though match between the elements wasn’t precisely Apple-precise, it felt sturdy and high-quality, and I would not be frightened about it falling aside or getting too crushed up inside a bag — although you’ll be able to pull the shell off should you attempt.

Perhaps do not pull too onerous (although it snaps again on simply wonderful)

All of the batteries have their outputs and inputs aligned alongside a single edge — objectively one of the best battery design. I hate it when one is on a unique aspect. Although port numbers and positions differ, all have 2-Three  USB Sort-A ports paired with a single USB Sort-C port for each charging and output, which maxes at 18W. A row of LEDs signifies remaining capability, with the highest LED denoting output by sort: inexperienced for commonplace, orange for USB-PD. A button on the prime triggers the LEDs to point out you the remaining capability, with a barely annoying slow-fill animation.

Nimble’s different obvious trademark function is a magnetic cable supervisor on the butt-end of every battery, and it is not executed too properly. The magnet included in it’s fairly weak, and the strap to carry cables itself is way too giant. The entire magnetic meeting fell off my batteries just about continually. Whereas it is a cool concept, the execution is not fairly there. Each a stronger magnet and a tighter strap can be wanted for it to be helpful, because it stands it isn’t value preserving in your battery whenever you toss it in a bag: it’s going to simply fall off.

Battery packaging is product of 100% “scrap paper,” optimized for recycling. Whereas I like the thought within the summary and I take pleasure in that ostensibly saves shoppers cash as nicely, the packaging is not very sturdy. The batteries are available a molded cardboard clamshell, they usually obtained a bit crushed up on their solution to my door. On one of many bigger batteries, a stickers preserving the 2 halves closed had even ripped open. Nimble appears conscious it’s kind of of a problem, as the most important battery is available in a extra sturdy and stereotypical cardboard field. Regardless, not one of the batteries have been truly harmed in any means throughout transit.

All the batteries excluding the most important one got here with the identical stuff: a 1′ USB Sort-A to USB Sort-C cable, a bag for recycling previous electronics, and a small product guide.

The most important, 26,000mAh battery comes with a dinky USB Sort-C QC 18W charger and an extended (~Three’) USB Sort-A to Sort-C cable. I discover it a bit humorous that the included charger is marketed as Qualcomm’s Fast Cost when the repeated advertising give attention to battery enter/output is USB Energy Supply.

I additionally had some reliability points with the USB Sort-C port on the most important battery. After some time, it stopped liking all of my USB Sort-C cables, and I needed to be cautious to not jostle it whereas it was charging, or it was susceptible to disconnect. The opposite batteries had no such challenge, although.

Nimble’s batteries embrace a 12-month guarantee, which is the naked minimal for batteries, for my part. Many OEMs present 12-18 month warranties with further extensions after product registration, and for Nimble’s premium pricing, I anticipated them to face by their merchandise for an extended interval.


We examined all 4 batteries in our typical trend, measuring watt-hours (over [email protected] 5V/2.4A), max enter, and max output throughout port varieties:

Capability 10,000mAh 13,000mAh 20,000mAh 26,0000mAh Max enter V (USB-C) eight.9V eight.9V eight.9V eight.9V Max enter A (USB-C) 2A 2.1A 2.3A 2A Max Enter W (USB-C) 17.8W 18.7W 20.5W 17.8W Max output V (USB-C) 11.6V 11.7V 11.6V 11.7V Max output A (USB-C) 1.4A 1.4A 1.4A 1.4A Max output W (USB-C) 16.4W 16.4W 16.2W 16.4W Max output V (USB-A) four.8V four.8V four.8V four.8V Max output A (USB-A) 2.3A 2.3A 2.3A 2.3A Max output W (USB-A) 11W 11W 11W 11W Watt hours over USB-A 30.2 39.eight 61 83.eight

There’s one main inconsistency I might like to notice, and that’s the USB-A ports that are not labeled as “Fast Charge.” Though each battery had the identical type of output on these quick charging ports, the opposite USB-A port efficiency diversified drastically, not simply throughout batteries, but between ports on the unit itself. A few of the ports might spit as much as 2.four A, whereas others could not exceed 1A.

Not all the USB-A ports behave the identical even excluding the “Fast Charge” port.

The batteries cost at a reasonably fixed 9V off of USB-PD, if they will get it, dropping amperage with time. None of my telephones ever appeared to have the ability to negotiate something over 5V on USB-C, but my MacBook Professional was capable of hit 12V.

The QC charger included with the most important battery hit a most of eight.8V and 1.9A, in my testing. It additionally did not appear to barter utilizing USB-PD in line with my tester, although that may be consumer error (I just lately obtained a brand new gadget particularly for testing PD compatibility, and I am nonetheless acclimating to it).

Do you have to purchase one?

In all probability not. Nimble costs approach an excessive amount of for these batteries contemplating their most output. 18W of energy over USB-C is fairly primary — it is not even sufficient to cost a laptop computer whereas it is actively getting used — and virtually each battery from the final ~5 years with 2.4A output comes near that. For much less cash, you will get batteries with USB-PD that hit 30W from different OEMs. For only a bit extra you will get one thing like RAVPower’s 27,000mAh battery,  which has an identical ~15W USB Sort-C output and a 70W AC outlet (and it was truly cheaper than Nimble’s largest battery once we had a coupon for it).

If these Nimble batteries might hit 30W or 45W over USB-C, I might think about them to be extra fairly priced, but throughout all 4 battery sizes, there are cheaper choices with the identical or higher specs. Our unique 15% low cost by way of coupon DROID15 makes it a little bit of a greater deal, but until the design actually appeals to you, different decisions persistently beat these batteries in a comparability of pure specs — and all at decrease prices.

With the financial savings ostensibly being introduced from using recycled supplies and environmentally pleasant, minimalist packaging, Nimble’s prices really feel disingenuous. Whereas I loved the construct high quality, general aesthetic, and use of premium supplies like aluminum and non-gross TPE (too many corporations use gross soft-touch black rubber), Nimble’s pricing is nonetheless unrealistic. The extra options built-in additionally fall flat: The magnetic cable administration is pointless contemplating how weak the magnet is and the way unfastened the flap to safe cables is, and the tremendous sluggish LED indicator animations have been irritating each time I needed to examine battery ranges.

Nimble must bump its output ranges or drop prices to get my unreserved suggestion.

events should purchase the batteries immediately from Nimble, or by way of Amazon.

  • “3-Day Charge”/10,000mAh – $49.95
  • “5-Day Charge”/13,000mAh – $59.95
  • “8-Day Charge” 20,000mAh – $69.95
  • “10-Day Charge” 26,000mAh – $99.95

Wi-fi chargers

Nimble technically gives 4 wi-fi charging merchandise: Wi-fi Pad, Wi-fi Twin Pad, Wi-fi Stand, and Wi-fi Journey Package. Nevertheless, there are actually solely three charging pads; the Journey Package merely incorporates the Wi-fi Pad and a bigger dual-port wall plug that, when put along with the pad, varieties a kind of field that the charging cable could be nestled in. Of this quartet, there are not any that I might notably advocate until you actually dig the aesthetic.

Design, hardware, what’s within the field

As we have seen from the batteries, Nimble locations a robust emphasis on their product design. The identical is true for its wi-fi chargers; all the things is wrapped in material that the corporate says is “made from organic hemp and recycled plastic bottles, and constructed with plant-based bioplastics derived from corn, sugarcane and other naturally occurring starchy fibers.” The grip pads on the underside are made from soft-touch TPE, they usually, too, are fairly particular. TPE supposedly requires little power to supply, and Nimble infuses mica crystals in every pad to create a 1-of-1 speckle design for every unit. The model, specs, and regulatory markings are engraved within the backside.


The Wi-fi Pad.

The eco-friendliness continues with the packaging, which is identical 100% scrap paper cardboard that the batteries arrive in. I personally did not have any points with the packing containers arriving broken, although they are not probably the most premium-feeling. Honestly, I felt like I used to be opening egg cartons, but hey, you’ll be able to’t complain about saving the world.

I am a fan of what Nimble’s completed with the supplies. The material gives a pleasant texture, and the TPE under retains the pad from shifting round. The rounded corners make for a pleasant, seamless look. The whole lot feels strong and nicely put-together, which is usually not the case for charging merchandise. A lot of the wi-fi charging pads I presently have use shiny black plastic. That appears alright when new, but it scratches and scuffs moderately simply. I do not see that taking place with material. Sadly, the wall plug is shiny plastic, but you are not going to see a lot of that anyway. No less than it has Nimble’s elephant emblem on it.


The Wi-fi Twin Pad.

The Wi-fi Pad, Wi-fi Twin Pad, and Wi-fi Stand every have one USB-C enter, in addition to a small indicator mild that exhibits when one thing is charging. All three help 10W quick wi-fi charging for telephones like Samsung’s flagships from the Galaxy S6 onwards, in addition to 7.5W charging for iPhones from the eight/X onwards. Different telephones will default to 5W. The Wi-fi Pad and Wi-fi Stand additionally every have one 5V/1A USB-A output, but that is one thing that I do not think about many individuals utilizing given how underpowered it’s. Maybe it might be good for charging your smartwatch or Bluetooth earbuds, but not a lot else. It also needs to be famous that the Wi-fi Twin Pad can have a most of 10W throughout each pads. So should you’ve obtained two telephones that help quick wi-fi charging on there, they’re each going to be caught at 5W.


The Wi-fi Journey Package.

The 2 charging pads are fairly self-explanatory, but the Wi-fi Journey Package and Wi-fi Stand in all probability require some description. The Journey Package consists of the Wi-fi Pad and a big, ~1-inch tall wall brick. Contained in the brick — which holds onto the pad magnetically — there are a retractable plug, two USB-A ports with a mixed output of as much as 5V/3A (considered one of which is, and a cubby to suit a charging cable in. The thought is which you could deliver your wi-fi charger with you if you’re on the go. I suppose it is an alright concept for those who really feel the necessity to use a wi-fi charger even if you’re on trip or a enterprise journey, but I doubt many individuals do.

Not probably the most safe.

At this level, I ought to in all probability point out that the wall charger portion of the Wi-fi Journey Package arrived faulty. It wasn’t capable of to attract energy from any of the retailers I attempted for longer than a second, so I substituted the very comparable bricks included with the opposite Nimble wi-fi chargers for testing. Nimble has knowledgeable us that an up to date model of the Journey Package will probably be launched within the subsequent few weeks, which is why it is at present bought out.


The Wi-fi Stand.

The Wi-fi Stand is one thing I flat out can’t advocate. It is nothing to do with the charging performance, as that is equivalent to the Wi-fi Pad’s, but it is simply poorly thought out. Nimble determined to make the stand parts (the bottom and the kickstand) retractable so as for it to perform as each a base and a stand. It is a good suggestion in principle, and one which Samsung has already executed, but it is simply not executed properly right here. The bottom, or no matter you name the half that the underside of the telephone sits on, is comically small. The kickstand additionally appears fairly weak. My check gadget was a Galaxy S7, a small telephone by in the present day’s requirements, and it was about to teeter proper off. I can not think about how a Pixel Three XL or an iPhone XS Max would stably keep on there.

Just like the batteries, every wi-fi charging gadget, save for the Wi-fi Journey Package, got here with a Fast Cost USB-A wall brick (5V/2.5A, 9V/2A, 12V/1.5A), a high-quality 1-meter USB-A to USB-C charging cable in gray, just a little plastic pouch for recycling previous tech, and a small instruction booklet. The Journey Package did not include the brick, because the package already features a dual-port wall charger designed to suit with the wi-fi charging pad. All 4 choices are backed by 12-month warranties.


Since we’re coping with wi-fi chargers right here, this part goes to be much less technical than the batteries’. Our check gadget was a Galaxy S7, which is provided with Samsung’s 10W quick wi-fi charging tech. For reference, the Pixel Three and Pixel Three XL additionally help a most of 10W by way of wi-fi.

Utilizing an influence meter, we clocked the utmost inputs at round eight.9V/1.1A, or ~10W, for all three Nimble wi-fi charger fashions. Meaning the scores are proper on the cash. It is value noting that the Wi-fi Twin Pad can solely deal with a most of 10W on each coils, which means that the utmost velocity if in case you have two telephones is 5W for each.

We additionally used Ampere to confirm how the Nimble chargers in contrast with an OEM Samsung wi-fi quick charging stand. The utmost enter that the app confirmed was 840mA for the Nimble fashions, which was about on par with what the Samsung charger confirmed.

Do you have to purchase one?

In all probability not. Simply as we noticed with the batteries, Nimble is charging higher-than-average prices given the specs its merchandise are providing. I am an enormous fan of the material exterior and TPE bases, in addition to the environmentally-conscious angle of a lot of the merchandise. Nevertheless, few will discover these design elements distinctive sufficient to warrant the upper pricing.

The Wi-fi Pad, at $39.99, is almost twice as costly as rivals on Amazon. The $49.99 Wi-fi Twin Pad is not as dangerous, but this $38 twin wi-fi charging pad not solely helps an 18W enter (9W on each coils with two telephones charging), but additionally has a further USB-A output on the charger. The $49.99 Wi-fi Stand cannot be really helpful for the identical financial causes, and that is to not point out how simply it might get knocked over with a telephone on it. Lastly, the Wi-fi Journey Package does not make a lot sense to me as a product, and at $59.99, it isn’t well-priced both.

As talked about beforehand, Nimble is providing AP readers an unique 15% low cost with code DROID15. That makes the prices barely extra palatable. If the material/TPE development actually speaks to you — and I can not blame you in the event that they do — be happy to go for both the Wi-fi Pad or Wi-fi Twin Pad. Even with the coupon, I do not assume the Wi-fi Stand is value it. The identical goes for the Wi-fi Journey Package, but that is type of a moot level provided that it isn’t at present for sale.
