There was a problem filtering reviews right now. Please try again later.
I first picked up the 20100 about 2 years ago, so it's not the newest product on the market, but it is one of the most affordable and reliable. It's also been revised several times as new technology is available, so it will keep up with todays devices. There's even a USB-C version now, though that's a review for another time.
First impressions, this is solid. Out of the box it has a nice heft and is well put together. No loose rattle or clicks. Button is smooth and responsive. Seams clean/tight and has a durable feel to the entire unit. Looks and feels well made. It's also held up well. In the two years since I purchased it, it's been annexed by teenage son. It's survived several drops, and daily being thrown in his backpack. It's not marketed as "rugged" but it has held up excellently to daily use/abuse. It is a little larger than most battery packs, but this is to be expected at a capacity of 20,100 mAh. Lithium cells can only get so small, but the unit is still very compact consider it barely larger than the six 18650 cells that power it. It won't fit in your pocket, but easily slips in a purse or backpack.
Performance has been excellent. Capacity is listed at 20,100 mAh but you need to keep in mind there is a conversion you need to do prior to matching to your phone capacity. For example, Anker states it will charge the iPhone 6s a total of 7.3x. iPhone 6s battery is 1715mah. 1715x7.3 = 12,520. Well below 20,100 mAh. But you are converting from a 3.7volt cell in the backup battery to 5V USB output. Then your phone is converting the 5V coming in typically back down to 4.2V. With these conversions you will have losses due to inefficiency, which is why your battery and phone heat up with use.
So, where does the 20100 fall? I hooked my unit up to a dummy load running 5v at 2A, using a smart multimeter, I consistently measured capacity at 13,640 mAh. Converting to watt hours (makes for easier comparison) = 68.2 Watt hours. Anker lists the battery pack at 74.37 Watt hours. 68.2/74.37 = 92% available capacity. Accounting for losses due to electric resistance and conversion, this is excellent efficiency. It also accounts for why the battery doesn't really heat up with use.
So real world use? iPhone 6 can recharge about 7.5 times. iPhone 7 about 7 times. When I tested with my iphone 7 I can typically get 6.8 charges before the battery pack is completely drained. So the advertised capacity is essentially dead on.
Charging, as other reviewers have noted, takes awhile. With a 2A charger this takes about 9-10 hours if the unit is completely dead. Since most people are not going to drain the pack daily, plug in at bedtime and it's ready in the morning. If you're using your phone charger it will take longer, but honestly if you're investing in this battery pack, do yourself a favor and pick up a quality wall charger (Anker sells several versions of those also :) ) When I used this on our last trip to Disney, it charged on average 3-4 phones/day and still had 2 leds lit. Plugged it in at night and it was full and ready to go by morning. Another very important feature is the dual USB outputs. Being able to charge 2 phones and stop siblings from fighting over the charger is priceless.
In all, this is a phenomenal battery pack and a steal at the current price. Catch it during a sale or with a discount coupon and it's a no brainer.
If you need a high capacity battery and don't need to worry about it fitting in a pocket, you can't go wrong with the Anker 20100.
I purchased this with my own money, did not receive any discount or incentives and was not asked by the company to write this review.
I purchased this product in August 2016. Pokemon Go came out in June 2016, and I was playing frequently for long periods of time and this charger was just what I needed to keep playing all day. This charger was extremely reliable. Didn't take long to charge, and the charge never decreased in output. I have purchased other Anker portable chargers after purchasing this one. The other chargers I purchased where larger versions of this one. This one was always my favorite, since it was a little smaller, but was dependable. It fit well in my back pocket, wasn't as bulky or heavy as the larger ones.
I have continued to play Pokemon Go and other cell phone games since I purchased this charger in 2016. This charger has been used frequently since it was purchased. There were times that I would use it during the day, charge that night so I could use it again the next day. I don't know how many times I have charged it over the past 4 years, not every day, but at least once a week if not 3-4 times a week. This charger has two ports, and I frequently would have two devices connected charging. I tried to completely drain the battery before recharging it.
This week the battery bit the dust. I am not able to charge it. I have tried different cables and wall adapters, and no luck. It lasted 4 years. Warranty is 18 months. I am disappointed that it finally bit the dust, just because it was my favorite. I have gone through more cell phones than Anker chargers since I purchased this charger.
I am going to purchase the current version of this charger to replace the one that just died. Amazing product, long life, excellent reliability, strong charging capability for the life of the charger. I highly recommend this charger and brand of chargers!
That being said, this battery pack is absolutely no exception. I figured between power outages, and the occasional travel with the kids, I should have a solid battery pack for our electronics. I've also discovered that I have several other items that charge via USB and this battery charges everything. I have a set of GMRS 35 mile radios which charge via USB on the charging dock. This pack charges them up without breaking a sweat. Even my small emergency radio can be charged via USB. I'm discovering that a lot of my things can be charged from this pack, which is a great investment.
It's got some solid weight to it. If you insist on packing light, you might want to consider a smaller pack from Anker. If you're looking for a lot of power in a small package, this one fits the bill. The two USB ports put out some great power at the same time. I've charged my Moto G4 Plus from zero to 100% in roughly 1 1/2 hour with the phone turned off which to me, is impressive. The four blue lights on the outside indicate how much of a charge you have and there's also a button you can press to get the power indicator lights to tell you how much juice you have. For the outdoors, I'd recommend purchasing a 10ft USB cable so the battery can stay in your pack, giving you more than enough cable to have handy for your GPS, radio, or phone. Anker makes some VERY nice cables that are perfect for the sportsman and the outdoors.
For the family, this thing can be a big lifesaver, providing essential power during an emergency or family trip when the kids need some more tablet time or during a power outage. This also comes with a carry pouch and a 3ft USB cable which is a big plus. The only downside to this pack is the recharge time. It does take considerable time to recharge it (roughly 8-10 hours), especially if it's completely drained. In my personal opinion, I believe the slow charge is to ensure the pack charges efficiently and correctly, just like a traditional battery charger. I'd recommend charging this pack overnight and it'll be ready to roll in the morning. After using this pack for several months, I'd recommend it to anyone without reservation, especially for it's battery strength and size. This is just about as much power as you can take with you in a small package and it hasn't let me down once. I'd buy another one with zero hesitation.
Top reviews from other countries
Very large charge, comes in a lovely box, a micro to usb-A cable and a nice little mesh bag to pop your battery pack in.
It charges my Galaxy s10 pretty fast and without any problems. Definitely charge this power bank overnight.
PACKAGING: I’m not usually one to care about how a product is packaged (as long it isn’t damaged in transit) - but I have to say, Anker has done a superb job packaging this thing. Maybe not quite at the Apple level, but not too far from it. As soon as you open the box, you get the impression this is a premium product.
BUILD QUALITY: I’m extremely impressed with the build quality of this product, especially given its very reasonable (dare I say low) price. It feels very dense and solid, while not being unreasonably heavy. At 358 g + 10 g (pouch) + 14 g (cable), this may be getting a bit heavy for hiking/backpacking trips, but is quite lightweight for just about anything else (car/plane travel, car camping, etc.). Speaking of the pouch, this is probably the best soft carrying pouch I’ve ever seen included with an electronics product. It’s made of a nice lightweight mesh, which is lined internally with a thin foam padding that gives added protection against bumps and drops. The USB A ports seem to be of really nice quality, and have a great feel to them when you insert a USB plug into them. This model has two USB ports, allowing charging of 2 devices (at up to 2.4A each) simultaneously - this is a very nice feature to save time when multiple devices need to be charged. The device has a small 4-light LED indicator that provides information on the current charge level, which is very useful for knowing how much juice is left in the battery pack. While not charging or being charged, pressing a small button on the side of the device will activate the LED indicator. The only minor complaint I have is that plugging a cable into the micro USB port is a little more resistant and finicky than I’d like.
CHARGING: When using this device to charge my Samsung Galaxy S7 Edge (3600 mAh battery), I get an average charging rate of about 1.3 minutes per % (so about 130 min. to fully charge the phone). This rate is similar to what I get from standard (non-fast charge) 2A wall chargers. The PowerCore has the capacity to fully charge the phone just under 4 times, which is expected given the 60-70% efficiency quoted by Anker on their website. In terms of how long it takes to recharge the PowerCore itself, it takes about 11.5 hours to go from empty to full (using a 2A USB charger). One nice feature to point out is that there is no on/off switch - when you plug in a device, it starts charging, and when you unplug it, it stops. So no need to worry about forgetting to turn the charger on or off.
PROS:
- Very well built, and seemingly durable
- Reasonable weight, given the charge capacity
- Good length micro USB cable and excellent quality carrying/storage pouch included
- Charge level indicator
- Charges devices at a good rate
- Does not need to be switched on/off
CONS:
- Time to recharge the PowerCore 20100 is somewhat on the long side, making things a bit tricky. For example, if you wanted to charge overnight, you’d need to start it charging a couple of hours before going to bed, and leave it charging for a couple more hours after waking up - this is a bit awkward.
CONCLUSION: Overall, I’m very impressed with this product. It appears to be a high quality product that offers a great set of features. No, it doesn’t have Quickcharge capability (either for charging or for being charged), but given its low price, it offers excellent value. Unless Quickcharge is important to you, I would highly recommend this battery pack to people looking for a super convenient way to charge their electronic devices while travelling.
PICTURES: Among the attached pictures, I’ve included one of the PowerCore 20100 beside a credit card, and another of it beside the PowerCore 10000, to give a relative sense of size.

Peso: 350 gr
Medida: 17cm x 6cm x 2.2cm
================================
Pros:
- Alta capacidad (20100 mAh).
- Acabados de buena calidad.
- Leds indicadores de carga.
- PowerIQ, carga a la máxima velocidad posible en cada equipo.
- Tamaño relativamente compacto.
Cons:
- No incluye cargador.
- Tarda 8-12 horas en recargarse (2amp)
================================
La batería tiene dos salidas USB (Tipo A) para cargar dos equipos simultaneamente, el micro USB es exlusivo para cargar la batería.
Inlcuye una funda de tela y un cable USB del color de la batería, aunque es posible encontrar una funda rígida aqui en Amazon.
Resulta bastante útil para viajes cortos/largos debido a su capacidad ya que se pueden cargar hasta 6 teléfonos, pero no sería mi primera opción para el día a día, para ello recomendaría más la versión de 13,000 mAh, pero al final depende de la necesidad de cada uno.
Lo que no me gustó es que no incluya un cargador y en mi caso no puedo usar el cargador del celular porque mi Moto Z es USB Type C.
Se necesita de un cargador de buena calidad para no dañar la batería y preferible de 2amp para reducir el tiempo de carga, de lo contrario puede requerir hasta un día en cargarse completamente. También es posible cargarlo con un puerto USB de la pc, pero tardaría bastante tiempo en completar una carga total.
Nota:
Este es el módelo más básico de esta capacidad y no cuenta con USB Type C ni tampoco viene con tecnología quick charge 3.0
