Flat 3-in-1 powerbank with Lightning, USB-C and Micro-USB connector

It’s not like I do not have enough powerbank. With me, a number of models fly around, but one thing was missing: A flat as possible power bank, which has a Lightning- and a USB-C and a micro-USB connector. Of course, after a bit of research, I found what I was looking for: The portable Charger power bank offers everything I wanted.

With the NebulAcc additional battery, the micro USB connector is firmly connected to the power bank with a ribbon cable. There is also a Micro-USB to USB-C and a Micro-USB to Lightning adapter. This gives you a lot of options for connecting to a wide variety of devices.

For me, this variety of connectors was important because I want to charge both my iPhone and headphones, the controller of the DJI Mavic Pro or the DJI Spark and my little MacBook. The Powerbank should be flat, so that I can take it with me in the MacBook bag and in my bag for the Mavic Pro or the Spark, without strong edges “threatening” the remaining equipment in the bag.

  • Portable Charger, Smart Identification Output: Connects your devices to maximize both compatibility and charging speed (up to 2.4 amps). Each port intelligently identifies your device to speak its unique charging language. This charging mode will be more efficient and secure. 5V, 2A input also helps you to charge the power bank speedly.

Technical specifications

For the sake of completeness, I would like to briefly list the “Specs” of the Power Bank:

  • Capacity: 5,000 mAh
  • Dimensions: 69 x 120 x 9.5 mm
  • Weight: 120 grams
  • Output: 5V / 1A (exact measurement below)

As an accessory comes next to the adapters also a small carrying bag made of felt, which holds the power bank in the main compartment, while the small mini bag on the front can be used for other accessories. A sewn rubber band holds the battery in the bag.

Handling the powerbank

A special feature of the NebulAcc Powerbank is, in any case, the flat design, which corresponds approximately to the thickness of my iPhone 7 Plus with a case. In terms of size, it is much smaller than an iPhone 7 Plus and is more comparable to the iPhone SE or iPhone 5.

Another handy thing about the extra battery is a small compartment in the battery itself, which holds an adapter. Since the tray is covered by the ribbon cable when the powerbank is not in use, the adapter also cannot fall out. He is also so tight on the tray, that you only get it out if you plug in the micro-USB plug and thus pull out the adapter.

And there we are unfortunately already at my only point of criticism: In the powerbank, itself is unfortunately only room for one of the two adapters. That is, one of the two adapters always flies “freely” around somewhere. With my (missing) order, it’s only a matter of time before he disappears. Now you might think that the felt bag still has room for the adapter. That’s right, but unfortunately, the small compartment in which you could accommodate the adapter, unfortunately not close properly and he can fall out during transport.

Apart from the disadvantage, the use of the powerbank is very easy. Pull the flat cable from the side of the powerbank, plug in the adapter (if necessary) and plug the cable into the device you want to charge. There is no button or the like to query the “level” of the battery, but as soon as a consumer is plugged in, the NebulAcc auxiliary battery with four blue LEDs will indicate its current capacity.

Charging current in the test

To test how much charging current the battery gives off, I compared it with a rather thick anchor battery, which provides with the PowerIQ function up to 2.4 amperes charging current – provided that the device to be charged draws, too so much electricity. In practice, I’ve found that my iPhone 7 Plus only uses just over 1.1 amperes as a charging current, while my iPad Pro 9.7 inches, after all, already absorbs 1.7 amps of charging current. The said 2.4 amps, which are advertised as I have never been able to measure and come in my view, at the most with the iPad Pro with 12.9 inches or MacBooks.

The values of the NebulAcc additional battery were only slightly below those of the Anker battery. Although only 1-ampere maximum output current is stated in the manufacturer’s description, in practice it has delivered more than 1.2-ampere charging current. A good value, I think …

A quick note on MacBook operation: While the MacBook is in operation, it indicates that it is charging, but in practice, the battery capacity drops, which is because the extra battery does not provide enough power to charge the internal battery while the battery pack is charging MacBook also needs power. Closing the MacBook requires significantly less power and the powerbank charges it up gradually.

So I would say that the power bank is more suitable for smartphones, tablets or smaller consumers. Laptops need too much power in a short time, which the powerbank cannot deliver. The 1.2 amps are simply not enough for laptops if you have them in operation while charging.

Conclusion to the power bank 

As already mentioned, there are certainly additional batteries that have more capacity and also charge connected devices at a higher charging current. The NebulAcc additional battery can not score either with regard to a particularly large capacity or with regard to a high charging current. The advantage of the NebulAcc lies instead in the flat design and the fact that you get two adapters on Lightning and USB-C included, which even partially find a place in the power bank itself. There is not much to complain about the additional battery in my view and I’m glad to have made the selection. If I suggest to the manufacturer to suggest an improvement, it would definitely be a space for the second adapter, so that an additional transport bag is unnecessary.

In practice, this extra battery with the adapters saves me from having to carry two to three charging cables, which I would have to pack with a normal power bank. That’s why the NebulAcc Powerbank – even with the above limitation – is a recommended accessory that I can recommend with a clear conscience.

Do you have Powerbanks who can serve you particularly well? Then I would be glad about your opinion and recommendations in the comments!
