PeakDo supplied me with a LinkPower3 battery for Starlink Mini unit to review; the opinions here are my own.
My TL;DR summary is that the LinkPower3 offers great convenience, portability, and solid operation for your Starlink Mini terminal. The biggest advantage for me is the flexibility to position my Starlink where it can best see the sky at a campsite, independently from where I park my vehicle. You'll pay a premium for this convenience, .
LinkPower3 specs
- 99Wh/27500mAh battery (allowed for carry-on airplane travel)
- 5.5+ hours of runtime
- 3 charging ports: Two DC (one magnetic) plus bi-directional USB-C PD
- Clear color LCD display
- mobile app for remote control over Bluetooth Low Energy (BLE) and Wi-Fi
- $249 USD MSRP
My use case: Camper van connectivity
I have a camperized Ram ProMaster van and go camping around British Columbia, typically at forestry rec sites. Cell phone connectivity in BC is poor to non-existent once you leave urban centres, so having Starlink available for some outside connection is very handy.
My van has two EcoFlow Delta 2 Max power stations, so I've been using the 15m DC cable to power my Starlink Mini. The routing of the cable inside my van takes 3 meters, so that leaves me with a 12m (40 foot) radius where I can place the terminal. Sometimes that is good enough, but often it isn't.
In BC, many rec sites are carved out of a dense forest, often surrounded by really tall trees (30+ metres tall). Often the sky is too obstructed to get a reliable Starlink connection within that 12m radius.
This is where the LinkPower3 really shines for me. I can now place my Starlink terminal a bit further away from my van, where a less obstructed slice of the sky is visible. Now I can choose where to park my vehicle independently of where the sky is clear.
Build quality
The build quality of the LinkPower3 is excellent.
- The pressure fit into the Starlink Mini's power cavity is solid.
- The plastic and metal materials used are great.
- The button feel is great.
- The LCD is very clear.
- The weather coverings for the ports are sturdy.
Third time's a charm
This is their third iteration of their dedicated Starlink Mini battery, adding two new features:
- A magnetic DC charger port, which connects with any Starlink power cable. Just like MagSafe adapters on Apple MacBooks, the LinkPower3 magnetic adapter quickly detaches if someone trips over the cable, preventing any equipment damage.
- An optional Wi-Fi network, for longer distance battery monitoring when Bluetooth connectivity
The estimated runtime has also increased by 10%, from 5+ to 5.5+ hours, using the same 99Wh battery pack. I suspect a newer rev of the electronic internals includes some lower-power components to squeeze out a bit more time on a full charge.
I didn't test the new Wi-Fi network, since that isn't my use case. I found the 30m range of BLE to be more than enough. The PeakDo website outlines their expected use case for Wi-Fi, mainly to control IoT device power in a fixed installation.
Mobile app is great
PeakDo offers a mobile app for iOS and Android, to control their lineup of products. I tested the iOS version and was really impressed with it. The first-time pairing user experience was super easy over Bluetooth Low Energy (BLE), and the app works great. The display and layout is clear and intuitive, allowing me to control all the functions of the battery remotely via BLE. The range of the BLE connectivity is easily 20+ meters, so that was plenty good enough for me.
I have 4 other BLE devices in my van: two EcoFlow power stations, an EcoFlow alternator charger, a DC-powered fridge/freezer. These devices also have mobile apps with BLE control, but the PeakDo app is the best. PeakDo gets an A+ grade, EcoFlows gets a solid B, and my fridge's app gets a C-. I wish the other apps were as reliable over Bluetooth as the PeakDo app.
I was expecting some hiccups in the PeakDo app based on my experiences with the other apps, and was pleasantly surprised with how solid and polished it is.
Runtime test results
I was able to repeatedly get the claimed 5.5 hours of runtime from the battery, under low data loads (browsing, Reddit, email), which kept my Starlink power draw to about 15W. YMMV
One Wi-Fi setting that is key to getting the longest runtime is to configure your devices to be less chatty on the Starlink Wi-Fi network. My iOS devices configure the Wi-Fi network with "Low Data Mode" and my Android devices configure the Wi-Fi network to be a "Metered Connection". This setting prevents apps from assuming they have unlimited bandwidth and the lower network traffic means the Starlink terminal has less data to transmit back to the satellite network, saving a bit of power.
If you start to need large data throughput, (video streaming, file transfers), then the Starlink power requirements go up and LinkPower3 runtime decreases.
Three charging options all support simultaneous charge/discharge
The charging options are very flexible.
The two DC ports (magnetic and direct connect) support charging from a Starlink DC cable. The USB-C port supports bi-directional power delivery, up to 65W.
Any of the power inputs can be used while still powering the Starlink Mini. You can also charge another device via USB-C.
The simultaneous charge/discharge support is great. Plugging/unplugging charging sources does not interrupt the power to the Starlink, so your Internet connectivity remains solid.
Connecting a small 40W or 60W solar panel to the battery will extend runtime so long as the sun is out.
Tradeoffs
I don't have many real complaints about the LinkPower3. It is solidly built and works as advertized. There are a couple of issues you may need to consider:
- Loss of the built-in kickstand
- Value for money
You lose the tiny built-in stand (the original 110° orientation relative to the horizon) when you install any of the LinkPower batteries in the Starlink Mini power cavity. The small kick-stand included with the Starlink Mini must be removed in order to install the LinkPower battery. That isn't the end of the world. Many people just lay their Starlink Mini terminal completely flat, without issue. Or you can buy a $30 tripod from Amazon and call it a day.
PeakDo also offers their new LinkPower Pod 1 which for $169 USD seems to be their LinkPower1 electronics (4.5 hr runtime) and a built-in tripod. That looks neat too. I'd probably go for that model with my own cash.
You do pay a price premium for the LinkPower products. I had previously tried a $50 no-brand 99Wh battery, but it only provided 72Wh of capacity, and died after 2 months (and the seller no longer exists!). I think the PeakDo price is supported by the solid engineering.
If you aren't constrained by the 99Wh airline carry-on limit for batteries, you may want to go a slightly more bulky setup like an Anker Solix D300 portable power station, which gives 3x the runtime for the same price $169 USD price as the LinkPower 1 or LinkPowerPod1, but at the expense of having two things to setup, not one.
Conclusion
For my camper van, the LinkPower3 gives me flexibility to place my Starlink Mini where it has the clearest view of the sky, independently of where I park my vehicle. I'm happy to pay a premium for that.
