Enjoy a Practical, Portable, Powerful 20,000 mAh battery bank from Odec.
I have had a love-hate relationship with batteries since my original Nintendo Gameboy, Walkman, and Diskman devoured many AA batteries. Looking back, I do not know why I did not simply invest in Duracell or Energize directly. As more devices moved to rechargeable onboard batteries, my need for AA/AAA batteries has decreased. However, I still utilize more AA/AAA batteries than I would like. I know I cannot be the only one who needs to charge their iPhone daily. Through daily phone calls, internet searches, game/movie/music/audible use, constantly searching for WiFi, checking emails, using GPS/Nav, etc., my phone hovers around 20% remaining power at the end of the day. While home, I place the phone onto a wireless charger or plug a USB-C to Lightning cable into the Lightning port. However, when on the go, I have learned to rely upon portable batteries. No matter if I am touring the Consumer Electronics Show in Las Vegas, Imaging USA in Nashville, TN, or camping with my pack of Cub Scouts, I look to 10,000mAh-20,000mAh options to keep me connected.
The Odec 20,000 mAh USB-C Power Bank arrived in a tan 6 9/16 inches long by 3 7/8 wide by 1 3/8 inches thick cardboard box. The main panel showed the Odec name along the top left, with a quaint little lightning bolt within the “O.” Beneath the name, you will find the battery capacity and an obliquely angled ink-outline of the 20K mAh battery. I visualized the circular power button, the four LED indicators, dual USB-A ports, and centralized USB-C ports within the image. Both sides displayed the same “GO GREEN WITH ODEC” logo, while the front and back panels were left unadorned. The bottom panel provided the OD-85 Model along the top right, product manufacturing labels along the bottom right, and the company web and physical address along the bottom left.
To access the Odec battery, I removed the thin outer plastic layer, lifted the front flap, the inner flap, and then removed the contents. Within the box, you will find a 2 1/8 inches wide by 3 3/8 inches tall 24-Month Product warranty card, a 3 3/4 inches wide by 2 3/4 inches tall User manual, a 48-inches long USB-C to USB-C cable, and the 5 5/8 inches long by 2 3/4 inches wide by 1inches thick battery. Before excitedly jumping into the testing phase, I decided to peruse the English section of the multi-lingual instruction manual (English, German, French, Spanish, Italian). The six-page English section was well translated, well thought out, and quite straightforward. The first page of the manual provided the package contents; the second page provided a labeled diagram of the 14.5-ounce battery. The third page provided a useful list of the product specifications (Model OD85, PD 3.0/QC 3.0, 20,000 mAh/74Wh LiPo, USB-C input/output AC 5V/2.6A 9V/2A 12V/1.5A, USB-A 5V/3A, 9V/2A, 12V/1.5A, Max 18W output, 142 x 68 x 28 mm, 5.6” x 2.7” x 1.1”, weight 410g/14.5oz). The instruction manual’s fourth page provided a few short paragraphs detailing power delivery (PD)/Quick Charge (QC 3.0). The fifth panel detailed the steps to charge the power bank and your device. Lastly, the sixth page reviewed the product care and listed warranty/customer support information. The manual could have used a little more detail about the device’s tech-specs (charging time, efficiency, etc.).
I grabbed my PA-Y19 Aukey 27W USB-C Minima wall charger and plugged the included USB-C to USB-C cable between the wall charger and the battery. Located along the battery side, adjacent to the 3/16 inches diameter power button, you will find a bank of four LED power indicator lights. I was pleased to find that the battery charged to full in only a few hours. Once the three solid white lights and the last solid green light were illuminated, I removed the battery from charge. I plugged a Klein Tools Multimeter into the USB-C output port and a USB-C to Lightning cable into my iPhone 12 Pro Max. Starting around 10% at 11:38 PM, the multimeter displayed 9.13V/2.14-2.18A. My iPhone 12 Pro Max increased to 14% by 11:41 PM, to 20% by 11:44 PM, 27% by 11:48, 32% by 11:51. 35% by 1153. 43% by 11:58. 50% by 12:02. 55% by 12:05, 66% by 12:12, and then 80% by 12:29. My phone then informed me that it had “OPTIMIZED BATTERY CHARGING” and that the charging was scheduled to finish at 5:30 am. True to the notification, I set the alarm for 5:30 am, and my phone read 100% power. Interestingly, the charging rate dropped from 9.13V/2.14A to 9.13V/0.2A and continued through the remainder of the early hours.
Once my 3687mAh iPhone 12 Pro Max battery was fully charged, I pressed the power button on the battery and found two white LEDs and one green LED were illuminated. I plugged the included USB-C to USB-C cable between the multimeter and my iPad Pro 11,” and the device screen read 9.14V/2.07A. Starting from a fully powered down state at 6:44 am, my iPad was at 43% by 7:37, 87% by 8:37, and 100% by 9:26. After charging the 7812 mAh battery of the iPad Pro 11” and the iPhone 12 Pro Max, the battery was 25%. I found that I could charge my AirPods Pro (519 mAh) fully before the last light was extinguished. This equated to 12018 mAh and roughly a 60% efficiency. I repeated the test with just my iPhone, using the top off my phone over the last five days. I still had roughly 50% of the battery left after that test. When fully depleted, the battery charged in about 3.5 hours via USB-C input (Aukey 27W USB-C). For my penultimate test, I plugged the KLEIN multimeter USB-A prong into the USB-A port and then a USB-A to lighting cable into my iPhone 12 Pro Max. The multimeter read 5.08V/2A. Lastly, I plugged a Drok USB-A multimeter into the USB-A port and the Klein Multimeter into the USB-C port. I charged my iPad Pro via the USB-C and my iPhone via the USB-A. The USB-A multimeter read 4.70V/1.32A, while the USB-C multimeter read 4.65V/1.98A.
I was pleased with the overall design, shape, mAh rating, and weight of the battery. When it comes to portability, I need a battery to weigh less than 16-ounces and provide at least 15,000 mAh of power. The battery bank from Odec sacrificed mAh for PD and QC 3.0. Although the device did not get too hot to handle, there was a noticeable increase in heat at the USB end. I loved that the device started charging instantly, and I was pleased that they did not add a wireless charging gimmick to this design. The hard plastic was quite durable and likely would survive a drop or two. I wish they would have included a carry bag/case or provided port covers/plugs for portability. Perhaps the features will be included in version 2.0 of the odek 20K mAh bank. The shape is perfect to fit into a pocket or a backpack. However, without a case or means to clip this to a bag, it must be carried or stored.
I do not feel that the PD/QC 3.0 trade-off was a negative feature. For a camping trip, I would prefer to have more total mAh than quicker charging. However, while touring CES, I found my phone drained by video/voice recording and a constant search for a signal. In that instance, I would have preferred a quicker charge in lieu of more power. With the ability to charge a phone up to five times or my phone/iPad/AirPods Pro once, look to the Odec bank as a perfect companion to a weekend away.
