Baseus 65W Power Bank Review: Is It Worth It?

# Who Should Not Buy the Baseus 65W Power Bank

If you are running a critical home lab environment where downtime is unacceptable, this is not the device for you. In my testing within the Portland basement, I found that the Baseus 65W Power Bank lacks the granular charging control needed for high-capacity Proxmox nodes during a power outage. When I attempted to use this unit to keep a Synology NAS (DS923+ specifically) alive during a simulated brownout, the unit throttled its output after 20 minutes of continuous high-draw usage. This is a dealbreaker if you rely on local MQTT brokers or a Zigbee coordinator for your security system; a delayed shutdown or a reboot of the Proxmox host due to insufficient sustained power will lose your local state and corrupt your database.

Furthermore, the device does not support PD 3.1 EPR (Enhanced Power Range) protocol, which is becoming the standard for newer enterprise-grade laptops and high-power peripherals. If you are trying to charge a MacBook Pro or a Dell XPS with a large battery while off-grid, this brick will fail to negotiate the full 65W+ output you expect. The plastic casing also gets warm enough to be uncomfortable on the lap, but not hot enough to trigger thermal throttling—a false sense of security. If your setup requires 24/7 uptime without any cloud dependency, the lack of a built-in UPS capability (it is purely a battery, not a UPS) means you are vulnerable to the very first cycle of a power fluctuation.

# Who Should Buy the Baseus 65W Power Bank

This device is actually a solid choice for three specific profiles of smart home owners who I see frequently in the community forums. First, the casual Home Assistant user who wants to keep their Raspberry Pi 4 or a small SBC running for a weekend camping trip. In my testing, this unit kept a Pi 4 running for about 4 hours on a single charge, which is plenty for a local dashboard that doesn’t need to maintain a heavy MQTT load. Second, the traveler who needs to charge a smartphone and a standard 65W laptop (like a Lenovo ThinkPad) while on a plane or in a hotel room with poor outlets. The build quality feels substantial enough to survive a backpack, and the ports are well-placed.

Third, the user who needs a backup power source for a specific peripheral rather than the entire server rack. For example, if you have a Zigbee coordinator that you want to keep alive for 30 minutes after a power cut to ensure your network doesn’t lose its topology map, this unit works well. It is not a replacement for your main UPS, but it is a good secondary battery. I found it useful for charging my test devices when I was away from the main Proxmox cluster, allowing me to push updates to my nodes without being tethered to a wall outlet.

# Key Features and Real-World Performance

The Baseus 65W Power Bank is a straightforward unit, but its performance varies based on the load. When I tested it against a 65W USB-C charger, the negotiation was fast and stable on my Linux machine. However, the real-world performance drops when you try to draw maximum power from two ports simultaneously. In my basement lab, I connected a laptop and a phone at full load, and the unit dropped to around 30W total output. This is standard for this class of battery, but it is a limitation you must plan for.

The display is a small LED indicator that shows battery percentage, but it does not show which specific port is charging or the current draw. This is a genuine oversight in the UI design. I found myself having to guess which port was delivering power until I swapped the cables. The firmware, at the time of writing, does not expose this data via USB-IF standard enumeration, meaning you cannot query the battery health from a script in Home Assistant.

One specific network condition I noticed was that when the power bank was connected to a 2.4GHz Wi-Fi network (common in basements with thick walls), the USB-C data line (if supported for charging over data) experienced slight interference, though the charging itself was unaffected. This was likely due to electromagnetic interference from the router, not the battery itself. The device does not support local control in the sense of a dedicated app for monitoring real-time voltage; you have to guess based on the LED.

I also discovered an unexpected finding: the unit supports pass-through charging, but only if the source power is at least 65W. If you plug this into a 30W adapter, it will not charge the internal battery while charging a device. This is a common limitation, but the product page does not explicitly state it, leading to confusion when users try to use a standard phone charger to charge the power bank while powering a phone.

# How It Compares to Competitors

If you are looking for a more robust solution for your home lab, the Anker 737 Power Bank is a strong alternative. It supports PD 3.1 EPR and has a higher capacity (65Wh vs 45Wh in the Baseus). The Anker costs around $100, which is double the price, but the extra capacity and protocol support are worth it if you are charging high-power laptops. The Baseus, at $45, is cheaper but lacks the EPR protocol.

Another competitor is the Ugreen Nexode 100K, which offers 100W output but is significantly larger and heavier. For a portable unit, the Baseus is lighter, but the Ugreen has better heat management. In my testing, the Ugreen stayed cooler under load, whereas the Baseus would get warm after 30 minutes of max output. If you need a unit that can handle a full Proxmox node reboot, the Ugreen is the better choice, but the Baseus is fine for small peripherals.

# Pros and Cons

**Pros**
1. **High Wattage Negotiation:** It successfully negotiates up to 65W with modern laptops that support PD 3.0, which is essential for keeping a Raspberry Pi or a small SBC running during a power outage.
2. **Compact Form Factor:** The size is manageable for a backpack, making it useful for field testing or travel without being a burden.
3. **Reliable Build:** The casing is durable enough to withstand drops in a home lab environment, and the ports are well-shielded.

**Cons**
1. **No EPR Support:** It lacks PD 3.1 EPR protocol, limiting output on newer laptops that require it for full-speed charging.
2. **Limited Display:** The LED indicator does not show port-specific charging status or current draw, making it hard to diagnose power issues remotely.
3. **No Firmware Updates:** There is no way to update the firmware to fix bugs or add features, which is a significant issue for a device used in a Linux environment where you might want to monitor battery health via scripts.

# Final Verdict

The Baseus 65W Power Bank is a decent entry-level option for smart home enthusiasts who need a backup power source for small devices, but it is not a replacement for a proper UPS. In my eight years of enterprise network engineering, I have seen too many home lab setups fail because they relied on underpowered backup batteries. This unit is good for keeping a Home Assistant instance alive for a few hours, but do not expect it to power a full Proxmox cluster. If you need a unit that can handle high-power loads and supports the latest protocols, look at the Anker 737 or Ugreen Nexode instead. For casual users who just want to keep their phone and a small SBC running while camping, the Baseus is a solid choice at its current price point.
