Travelling light – Part II on the field

Disclaimer: there are many USB power banks on sale however most of them do not declare the maximum output current and therefore you cannot be sure that it will work in all situations I describe. The equipment I use does work and is proven by my daily experience, the suggestions are not prescriptive but if you choose your own parts you do do at your own risk

It has been some time since my post on chargers and recharge facilities. During the pandemic I have done a considerable amount of land based photography including wildlife, landscape and astrophotography so I have had the opportunity to develop the concept of portability further on the field. So I wanted to share my experience with you all as some of the findings are beneficial in every day situation.

Charging your camera battery

Today some cameras can charge the battery in camera using USB. In almost all cases the camera needs to be turned off to allow charging, as a complete recharge of your battery can take a few hours I never use this method. I always rely on spare batteries typically 3 and a dual battery charger that can be powered using USB. I use Newmova they are cheap and cheerful for both my Panasonic and Olympus cameras.

With 3 batteries you can have two in the charger if needed and one in the camera which means uninterrupted shooting for a long period of time depending on your use.

Battery Grips

I also use battery grips in particular for my Olympus camera. Battery grip provide the most benefit when you are not wanting to interrupt shooting while swapping batteries. I usually set the camera to use the grip battery first and the camera as back up which means you can then insert another battery in the grip and keep shooting. I do not recommend using a battery grip as a sole source of power as at the end you can can go through 2 batteries relatively fast if you use quick burst shooting. The other dis-benefit of the grip is the one battery is always locked inside the camera so you need to increase your total battery stock to 4 if you use a dual charger. The grip is very useful to shoot verticals and provide weather sealing but overall is not my favourite option and I only use it for specific session on my Olympus camera because I only have 2 batteries.

There are some working 3rd party battery grip like this one that function AS LONG AS YOU USE ORIGINAL OEM BATTERIES.

I have not seen versions for Olympus camera and the original battery grip is expensive. I got mine second hand for a good price.

Again if you only have two batteries or you want to rotate 4 batteries a battery grip is a good option if you don’t mind the extra weight.

Power Banks

I use a relatively simple USB power bank as I do not have PD capable cameras. This power bank has a decent capacity but more importantly it can output 4.5A using two outlets.

RAVPower Portable Chargers 16750 16750mAh External Battery Pack 4.5A Dual USB Output £24.99 

This power bank has also a light included very useful for your night photography. You can also use it to charge your phone but with two outlets means you can power two dual USB chargers and effectively charge 4 batteries twice until it runs out (typical battery less than 2000 mAh).

This power bank can also be used as constant power supply for cameras that take a dummy battery and do not support powering through USB.

DMW-DCC12 USB Power Cable kit DMW-DCC12 DC Coupler Dmw-Blf19 Dummy Battery (BLF-19 Battery Replacement) Compatible with PANASONIC DMC-GH3 DMC-GH4 DMC-GH3K DMC-GH4K DC-GH5 GH9 and more Digital Cameras £22.99

Using the power bank with this fake battery kit means I can run my GH5 in video for days (8.72x batteries equivalent charge).

IT IS VERY IMPORTANT THAT YOUR POWER BANK OUTPUTS MORE THAN 3A OTHERWISE IF YOU USE MECHANICAL SHUTTER THE CAMERA MAY GO IN SHUTTER VIBRATION AND SUFFER PERMANENT DAMAGE

Some well know power bank from respectable brands like anker and even rawpower themselves only outputs 3A current total so when the mechanical shutter is used and the camera draws more current you run into issue. This also happens when you set a custom white balance and the camera triggers the mechanical shutter. So if you have such power bank you are limited and hence I do not recommend them.

If you also use flash you can use the same chargers I already linked in the previous article

Prices have dropped to £7.99 for the micro USB and £9.99 for the dual USB C and micro USB input. Note that despite the misleading description the two chargers are identical except one has micro USB and the other also USB-C. The USB-C version is slightly bigger (70x90x23 mm USB version vs 97x114x34mm USB C). The USB C version has a stronger output for AAA batteries that I do not use and it does not charge faster standard AA so don’t be mislead.

Dew Heaters

Another useful accessory if you do astrophotography in humid or cold environment is a lens warmer. There are two versions I recommend the one with the temperature regulator as the strip gets to 50 C and this can increase dark current noise in your shots.

Travelling light – Part I Chargers

Disclaimer: there are many USB chargers out there and not all of them have performance level adequate to support your underwater photography needs. Make sure that each USB-Type A outlet is at least 10W and that the total power equals 10xnumber of outlets as a minimum or your USB charging will be slow. If you get an USB-C charger make sure that the power allocated to the USB-A outlets is enough or your laptop will charge very fast but your batteries will take forever. The product I am suggesting here have been researched and I have tested them on the field I do not take responsibility if you get something different because it looks cheaper or newer. In case of doubt happy to take questions.

Few months ago I booked a shark diving trip. Looking at the boat specs I realised the vessel was smaller than those I have travelled in the past and therefore I was concerned that with many photographers on boat it would have really been a struggle to have all my chargers especially as there were only shared cabins. Furthermore many boats do not allow anymore to charge batteries in your cabin to reduce the risk of fires,

I put my items on a scale and I realised how much this whole set up weights

Charger spaghetti and one strip

I contacted the boat that told me strips were available for power but of course US format so not good for me. 1.8 Kg for a single AA battery fast charger, laptop power supply, phone charger, camera batteries charger. 1.8 Kg without even including the back up AA charger in the image below. Of course I can find a lighter strip or have a number of US adapters but you can see this is not heading in the right direction.

Chargers for a typical underwater photography typical trip

I recently bought a new MacBook Pro that only has USB C ports this has made me realised how powerful USB has now become with USB C you can deliver power to charge a large laptop as well as transfer at light speed images and especially videos. I will write another post on how to make your physical media management more effective but for now let’s focus on power.

At the same time in our home there is competition for charging tablets, phones and all sorts of other portable equipment by USB.

I thought would not be nice to have a multi USB charger? Do they even exist and the answer is yes. See below a product I bought for home and travel use that can power up to 4 devices.

Wall Charger, RAVPower 40W 8A 4-Port USB Charger with iSmart 2.0, Travel Adaptor for iPhone XS/XR/XS Max/8/8 Plus, Galaxy S9/S8/Note 8, iPad, Tablet, Kindle, Power Bank & More – Black

£15.99 to end all our struggles seemed a great deal. You can directly click the image above to buy it on amazon.

In US this is $16.99 so even cheaper

RAVPower USB Wall Charger 40W 8A 4-Port Multi-Port Travel Charger Charging Station, Compatible iPhone Xs Max XR X, iPad Pro Air Mini, Galaxy S9 S8 Note 8 Edge, Smartphone, Tablet and More

From there I started thinking is there a way to charge AA batteries using USB after all the current requirements are quite low?

So I found this other product that did the job and can charge 4 AA or AAA batteries for £14.99 on Amazon. Note that despite the misleading description the two chargers are identical except one has micro USB and the other also USB-C. The USB-C version is slightly bigger (70x90x23 mm USB version vs 97x114x34mm USB C)

From there I moved to camera batteries and I found another product that allows to charge two batteries at the same time as battery consumption for video is huge. £8.49 seems a bargain click and see for yourself!

When you hit the page you can also buy compatible batteries this is not recommended please buy original batteries there is a whole world of difference.

At this stage my travel charger was using 2 ports for AA batteries 1 for camera dual battery charger with one spare for the phone or other devices.

I though is there a charger that also has a UBC charging port so I can also get rid of the laptop charger and there is £27.99 on amazon click on the image to go directly there.

At this point streamlining was complete. As additional benefit the desktop charger has a removable power plug so you can get your cable for EU or US or any other country the device will work anywhere. The only item still to be worked on are video lights but with batteries of 99 Wh this is not yet possible.

I put all on the scale well it speaks for itself 1 KG less

Of course many people do not have USB C powered laptops yet but this is changing so I would recommend getting a charger with USB C however if you don’t want or need that there is also a charger without with 4 or 6 ports

Of course you have put all eggs in one basket now but frankly it was the same also before if one of the charger would fail and besides you will find USB chargers on a resort or a boat as anybody as a phone. Worst case you can bring two power suppliers however this looks unnecessary to me.

I hope you find this useful feel free to share this page with your friends and use the links on here. I have looked into products in details those are the best ones that have the features you need (2.4A current at least 45W USC B won’t bore you with details but trust me this is what you need).
