REVIEW – Voice in your Head: Here we go again, another portable charging solution.  Me: Ah, but this one has a bit of a twist.  The Renogy 10,000mAh Solar Panel Water Resistant Power Bank has not only a solar panel for backup charging, but is also water-resistant.  Other products may offer one or the other of those features, but how well did Renogy combine them?  Let’s check it out!  Gadget on!

What is it?

The Renogy 10000mAh Solar Panel Water Resistant Power Bank is a water-resistant, shock-resistant and dustproof portable phone charger with a solar panel backup.

  • Dual USB output ports, 2.1A for tablets, 1.0A for phones
  • Micro USB input port
  • Water- and shock-resistant
  • Solar panel for backup charging
  • Dimensions = 5.4 x 2.9 x 0.6 inches

Design and features

renogy solarpowerbank 02

The very first thing I noticed above the device was its soft, matte finish, which felt very comfortable to the touch.   Additionally, a solar panel covers most of the top of the device, as seen in the photo above.

Also, despite it having a water-, shock- and dust-resistant case, the device had a nice size and relatively slim profile, and looked rugged.  In addition, each of the corners is built-up to provide additional shock- or drop-resistance.

The device is a nice size and fits well in my hand.  I also like the side notches as well as the scallops on the front and back.  All of these contribute to providing a bit more grip on the device.

The sides of the device have orange silicon panels which not only aid in grip, but also give it a bit of visibility.  Why is this useful?  Because I found myself digging around in the bottom of my EDC bag for this device on a couple of occasions when the lighting was sub-par, and the various orange silicon panels held me locate it.

There is a single push button-style power button along the side corner of the device.  It has the same orange silicone coating as described above, which contributes to the device’s water- and dust-resistance.  This button can be pressed to activate charging if it does not begin automatically when something is plugged into it, as I found occasionally happens.

The device is equipped with a light on the back, which is activated by holding down the Power button for a few seconds (see photo above).  Once illuminated, the light can be made to flash in an emergency strobe mode by holding down the button for another xx seconds.  Another press deactivates the light.  The light is bright enough for nearby, but not bright to light your way through a dark woods on a moonless night (it doesn’t throw light very far).

There is a small plastic clip on the back of the device.  Because it’s plastic, it looks and feels a bit flimsy.  I haven’t broken it (yet), but it feels as if it were flexed too far it would simply snap off.

The device’s power level indicator consists of a row of five tiny LEDs.  During charging, the LEDs illuminate to indicate charging status; when the LEDs turn off, the device is fully charged.

The device has a cover made from the same flexible orange silicone material as described above.  This cover protects all of the ports (see photo below) from dust, water splashes or perhaps even a light rain, but I have my doubts that it would protect the ports against a heavy rain and certainly not against full submersion, at least for very long.

As seen in the photo above, the device has two (2) USB output ports positioned to the left and right a single Micro USB input port. One of the USB output ports provides 2.1A for charging tablets while the other provides 1.0A for charging phones.  I like that it has two output ports to allow charging of two devices simultaneously, but there is no indicator as to which is the 2.1A and which is the 1.0A.  Frustrating.

The instruction booklet recommends that the devices primary charging method is via the micro USB input port (see included cable plugged into the input port in the photo above), which does charge the device faster than the solar panel.

renogy solarpowerbank 04

The device’s instruction manual recommends solar charging as a backup/emergency charging method only, because it is slower than wall charging via the micro USB port.  However, I noted that the device basically charges any time the solar panel is exposed to a light source, whether it be direct sunlight or artificial light.  As with USB cable charging, when the device is turned toward a light source, the bank of LED lights illuminate to indicate charging status.

I used the device to charge both my wife’s iPhone X (pictured above) and my iPhone 6 Plus, and it charged both phones at a reasonable rate.  It also charged my Garmin Fenix 3 HR GPS watch without an issue.  However, this device does not include pass-through charging, meaning it cannot be used to charge a device while being charged itself.  This is a big minus for me as when I travel I often take a single portable power bank that has multiple USB ports and use it to charge multiple devices while I charge the power bank itself, rather than take several individual chargers.

What I like

  • Backup solar charging
  • Water-resistant
  • Light with emergency flash mode

What needs to be improved

  • No pass-through charging
  • No way to identify the 2.1A vs. 1.0A USB output ports

Final thoughts

The Renogy 10,000mAh Solar Panel Water Resistant Power Bank is overall a well-built and useful piece of gear.  I like that I can toss it into my EDC ruck and have not only a backup power source for my devices, but the solar panel means I have an emergency source if necessary and also I don’t have to be as concerned about getting it wet or dropping it as I would be with devices that are less rugged. Overall, for its fairly unique feature set, its price of $20.99 seems like a pretty good deal.

Updates 09/11/18

Shortly after this Review was posted, a reader commented that I had not done much testing on this device’s solar charging capabilities, and this was a fair comment. I did some additional evaluation of the device, focusing on the solar charging feature. My initial assessment was that the solar charging feature appeared to be working, based solely on the fact that the small bank of LEDs on the device was illuminating while the device was placed in the sun or another light source; therefore, I naively assumed that solar charging was actually happening. However, further evaluation unfortunately proved this assumption to be incorrect. Although the LEDs were indeed illuminating when the device was placed in a light source, it was not actually charging. In fact, I placed it in direct sun for the better part of a full day and it did not charge up at all during this time. This is appears to be a lack of performance of one of the main and more unique functions of the device. It works fine when charged with a cable, but the solar charging basically does not appear to work properly. Apologies for missing this in my initial evaluation, and thanks to reader Greg for prompting me to do a more thorough evaluation and report back here.

Update 6/26/20

This power bank is smallish, lightweight, and rugged, but as stated in the 09/11/18 update, the solar charging capability of this item never did work properly, which was disappointing. However, its ruggedness and LED light do make it useful, so I sometimes grab it to toss in my bag for travel.

  2. I believe the problem with the solar charging is the continuous activation of the colored led’s using up most of the solar power being generated. If these could be turned off while solar charging it may charge faster.
    I use a 10 watt solar panel to charge the phone and it works well in strong direct sunlight.

  3. I do not have this one, but a similar 10k mAh Renogy solar battery pack. I just got it today, but it appears to take a very long time to charge in the sun. Reading the manual, it says 30hrs in direct sunlight to charge it 50 percent. Given that the average amount of good sun is 8-10 hours a day, that means it would take a week to fully charge. It is a 2w solar panel. Maybe this one is the same?
