If your laptop plug is a USB-c (small rounded rectangle) you are good to go. It has 3 output ports. Bought a simple USB-c pd female to barrel connector to make the connection.

It is the cheapest of all the 60w pd battery banks available on amazon. I’m glad i finally found this power bank that was true to it’s output specifications. It’s perfectly rated for my 65w ts100 soldering iron.

Seller needs to be more transparent with what the item actually is. It has an in and out jack, but regardless of which you use, it doesn’t charge your laptop. Maybe it is a good charger for phones and tablets, but that’s not what i thought i would be. Read

If you’re one of the lucky owners of a Steam Deck, you already know how awesome it is to have a handheld PC that can access a bunch of titles from your ever-growing Steam library and run them well. However, if you plan on taking the Steam Deck places, you should consider having a power bank.

Why? Well, the Steam Deck’s battery life will vary based on the game you’re playing; sometimes, you net five hours of fun, and other times it’s a mere three, regardless of battery optimization. A power bank saves you the need to visit a nearby outlet; instead, you plug in the charger and attach it to the device, and you’re good to go—(almost) unlimited power at your fingertips!

Here are the best power banks for the Steam Deck.

Baseus 65W Power Bank

Budget price, premium power

The Baseus 65W Power Bank comes equipped with an LED screen for easy battery gauging, a 20000mAh capacity, and a durable exterior.If you’re noticing lackluster performance in the battery department of your Steam Deck, this power bank from Baseus is the boost you need.

  • Recharges to full capacity in 2 hours
  • Excellent durability
  • LED screen displays remaining battery, voltage, and current

Portability, good capacity, and excellent durability—these are the three pillars that hold up the Baseus 65W Power Bank as one of the best power banks for Steam Deck. In addition to being a well of power, the Baseus 65W Power Bank provides more bang for your buck with a few welcomed features.

For starters, the Baseus 65W Power Bank has a maximum capacity of 20000mAh, which can fully charge the Steam Deck nearly four times. That’s more than enough power to get through the day’s errands, especially if you know you’ll have downtime along the way. And since it’s relatively small and durable, thanks to its metal casing, you can safely toss the Baseus 65W Power Bank into a travel bag and never worry about damaging the hardware.

Anker PowerCore

The perfect travel companion

The Powercore from Anker is capable of charging two devices at once, meaning you can keep your Steam Deck and external controller or Bluetooth headphones at full battery for your entire gaming session.And with a speedy 45W USB-C port, topping off your electronics won’t feel like watching paint dry.

  • Can charge the Steam Deck five times
  • No bigger than a smartphone
  • Easily portable

Fully charged, the Anker PowerCore has 26800mAh to work with, a capacity that’s great enough to juice up the Steam Deck fully five times—as long as the power bank is used solely for the Steam Deck and the power isn’t split with another device. importantly, the USB-C port peaks at 45W, which is right where the output needs to be for the Steam Deck to charge in a meaningful timeframe.

In addition to outstanding performance, the Anker PowerCore also provides the perfect ratio between size and maximum capacity, making it an ideal candidate as a travel companion. Considering it’s not much bigger than a smartphone, the Anker PowerCore is slim and small enough to slip right into your However, you’re just as likely to make use of the included travel pouch if the day calls for some outdoor adventuring.

Given the size of the Anker PowerCore and its performance, the power bank is definitely best utilized as a backup power supply for the Steam Deck. And if, say, your smartphone is about to die, it even has a bit of power to spare in a pinch.

Elecjet PowerPie P20

Elecjet’s PowerPie P20 is your.sized companion for a long and healthy Steam Deck battery life.With a 20,000mAh capacity and both USB-C and USB-A ports, the PowerPie P20 is a simple, effective, and lightweight power bank that can fully recharge your Steam Deck in under a few hours.

  • Lightweight travel option
  • Doesn’t take long to reach max capacity
  • Can charge 2 devices at once

With a slim and lightweight design, the Elecjet PowerPie P20 is the perfect power bank for your Steam Deck if you’re aiming to gain the most power per ounce. Given its dimensions, this portable charger is comparable to the smartphone in your hand, making it an easy choice for the sake of traveling.

The Elecjet PowerPie P20 comes fitted with a single USB-C and USB-A port, which is great if you need to charge something other than your Steam Deck. In fact, with its 20000mAh battery capacity, you can spare a portion of the battery and still charge the Steam Deck more than once. However, if you’re using the power bank strictly for charging your gaming device, you can get nearly four full charges!

Best of all, getting the Elecjet PowerPie P20 Power Bank powered back up doesn’t take long. Fully depleted, it takes just 2.5 hours to fully recharge the battery, so if you plug it in shortly before you go to sleep, it’ll be ready in the morning. It’s slim, fairly lightweight, and easily tops off the Steam Deck multiple times over.

Crave PowerPack

Charge all of your gadgets at once

The Crave PowerPack is capable of charging your Steam Deck over nine times; you might as well have a generator in your If you need to charge accessories alongside your Steam Deck, the PowerPack has four total USB ports for three additional devices.

  • Massive capacity
  • Can charge the Steam Deck nine times over
  • Great choice for outdoor adventures and power outages

The Crave PowerPack is a high-capacity battery that, at full charge, provides 50000mAh of power to any given device. In the case of a Steam Deck featuring a 5313mAh battery, you’ll be able to fully charge the handheld gaming device nearly 9.5 times before draining the power bank completely. Of course, that’s quite a bit of power for one device, so if you need to charge your smartphone quickly for emergencies, the Crave PowerPack has plenty to spare.

Keeping the hardware safe inside is a hard plastic casing that’s fairly durable; the Crave PowerPack has the strength to withstand a few bumps and drops without damaging the internal electronics. While you can rest assured that it won’t shatter the first time it drops, the Crave PowerPack is far too big and bulky to carry freehand, so you’re better off avoiding the matter altogether by storing it in its included travel case for safekeeping.

importantly, the Crave PowerPack features a total of four USB ports for charging your Steam Deck or, alternatively, for recharging four devices all at once, which definitely comes in handy during a long trip or power outage. It also has a helpful LED indicator to display the remaining battery life.

Krisdonia 60000mAh AC Power Bank

Massive battery capacity for multiple recharges

With this much capacity, your Steam Deck might as well have an all-day battery life. Its 20W Type-C port pairs perfectly with your Valve handheld, enabling the Steam Deck to last as long as you do.

  • 60000mAh capacity
  • Can fully charge the Steam Deck 11 times
  • Excellent companion for traveling

Say you’re planning a short trip—something that could span a day or two—and you aren’t sure if you’ll have access to a power outlet. Whether you’re going on an extended business trip or enjoying the outdoors for a few nights, you’ll want the Krisdonia 60000mAh AC Power Bank in tow, especially if you’re bringing your smartphone and Steam Deck with you.

If the name hasn’t given it away already, the Krisdonia AC Power Bank has a massive maximum battery capacity of 60000mAh. Considering the battery capacity of the Steam Deck is only 5313mAh, the Krisdonia 60000mAh AC Power Bank has enough juice to charge the Steam Deck 11 times over and then some. What’s also nice is that you can keep track of how much power you’re burning through by using the helpful LCD that displays the remaining charge.

With that said, the Krisdonia 60000mAh AC Power Bank is a bit overkill if you’re using it solely for the Steam Deck. It’s best used in the hands of someone who travel often and needs several devices charged at once, given that it has four options for powering devices.

Crave Plus Pro

The Crave Plus Pro is built to last. With its aircraft aluminum exterior, drops and dings are problems of the past.The burly durability doesn’t mean the Crave Plus Pro falters on efficiency, though. With a 20,000mAh capacity, Crave’s Pro power bank can recharge your Steam Deck to full battery well over three times.

Are you prone to accidents? Or, maybe, you value durability above all else? In either case, if you’re after high-end ruggedness, look no further than the Crave Plus Pro.

The Crave Plus Pro foregoes the common use of plastic, which scratches quite easily, for a much sturdier material: aircraft aluminum. By dropping plastic for aluminum, the Crave Plus Pro can take a great deal of abuse, not to mention extending its lifespan. It also doesn’t hurt that the metal casing is nicely designed, giving the power bank a premium look.

But what about performance? Surprisingly, the Crave Plus Pro doesn’t hold back. It has a maximum capacity of 20000mAh, providing enough juice to charge the Steam Deck over 3.75 times! Considering the Steam Deck has a battery life lasting two to eight hours, that’s an extra 7.5 to 30 hours of playtime, depending on the title. In fact, the Crave Plus Pro delivers power at the same rate as the Steam Deck’s original charger, so it always gets powered efficiently.

Anker PowerCore III Elite

Smart, efficient power distribution

Anker’s PowerCore III Elite power bank may not have the single largest capacity out there, but it shines in its Smart power distribution and durable design.And, if you have more than the Steam Deck to keep powered, the PowerCore III Elite has ports for charging three devices at once.

  • Recharges in under two hours
  • Automatically adjusts voltage to match the device
  • Not much bigger than a smartphone

The Anker PowerCore III Elite reminds everyone that effectiveness has its place; it’s an aspect that power banks can easily overshadow with massive maximum capacities. What’s the use of all that power if it gets wasted? With the Anker PowerCore III Elite, you get a respectable power bank that puts efficiency above all else.

For starters, it has a maximum capacity of 25600mAh. That’s enough to charge the Steam Deck fully about five times or, in other words, 7 to 28 hours of extra game time. That’s all fine and dandy, but it’s how the Anker PowerCore III Elite delivers the power. It automatically adjusts its maximum power distribution to perfectly match the device it’s connected to—in this case, from 60W down to 45W to match the Steam Deck’s original charger. And if you need to charge a different device in a pinch, it has a Trickle-Charge mode for lower-power devices like Smart smartwatches or earphones.

The Anker PowerCore III Elite makes the best of its plastic casing. Rather than opt for a smooth, featureless exterior, the Anker PowerCore III Elite has a nice textured surface, making it much easier to grip and prevent accidental drops. Of course, there’s no reason not to use the travel bag included with the Anker PowerCore III Elite.

Omnicharge Omni 20c

A power bank and USB hub in one

Omnicharge’s Omni 20c is far more impactful than your everyday power bank. While it can charge your Steam Deck back to life with no problems, it also doubles as a USB hub for your daily driver gadgets and peripherals.

  • Doubles as a power bank and USB hub
  • Sturdy construction
  • OLED screen provides oodles of data

If you’re looking for a power bank that’s far more versatile, you may want to consider the Omnicharge Omni 20c, which features a 20000mAh maximum capacity and four USB ports. However, that’s only the beginning of what this portable charger offers.

Given the number of USB ports available and 10W wireless charging on the top, the Omnicharge Omni 20c isn’t just good for charging your Steam Deck, but multiple devices at once. Why stop at charging the Steam Deck when you could charge your smartphone at the same time? On top of that, you can use it to transfer files to said device, which essentially turns it into a power bank and USB hub wrapped into a rather small device.

Considering how useful the Omnicharge Omni 20c is, you’ll want to take it with you, right? Luckily, the power bank has a rubberized outer shell that feels good in the hands, keeps most fingerprints at bay, and grips the table pretty well.

Finding the Best Power Bank for Your Steam Deck

There are several factors to consider when picking the right power bank for your Steam Deck. You’ll want to take battery capacity, durability, connectivity and compatibility, and form factor into account.

If there’s any power bank that shines in every category, it’s the Baseus 65W Power Bank. It features a tough chassis, portable, and a maximum capacity that allows you to push the Steam Deck to its limits without having to camp out by your electric outlet.

With that said, if you don’t mind dropping a few amenities, the Elecjet PowerPie P20 is perfect for tight budgets, especially if your Steam Deck is still fresh. It isn’t as durable as the Baseus 65W Power Bank—plastic as opposed to aluminum—but you’ll still fully charge the Steam Deck multiple times, while maintaining the minimum power delivery requirements.

Baseus 65W Power Bank

Budget price, premium power

The Baseus 65W Power Bank comes equipped with an LED screen for easy battery gauging, a 20000mAh capacity, and a durable exterior.If you’re noticing lackluster performance in the battery department of your Steam Deck, this power bank from Baseus is the boost you need.

FAQ

Q: What Do I Look for in a Power Bank for Steam Deck?

You want the power bank to accomplish two things: the maximum capacity should be more than the Steam Deck’s battery, and the power output should match the Steam Deck’s original charger. The Steam Deck has a 5313mAh battery and a charger that caps its energy output at 45W.

To put that in perspective, a power bank with a maximum capacity of 5313mAh could fully charge the Steam Deck once. As for the charger, anything with an energy output lower than 45W will charge the Steam Deck at a much slower rate or, potentially worse, not charge it at all.

Q: What Does ‘Pass-Through’ Mean in Connection With Power Banks?

Pass-through technology is simple: if a power bank has that feature, it can charge devices and be charged via outlet simultaneously.

It’s a very convienant feature to have, not to mention incredibly efficient. Why charge both devices separately when you can do both? However, not all power banks have pass-through technology, so if that’s a feature you’d like to have on hand, double-check with the product’s specifications first.

Q: What Does mAh Mean?

You’ll quickly notice that all power banks have a number followed by ‘mAh.’ That stands for milliampere hours, a measurement determining a power bank’s maximum capacity.

When picking a power bank, the higher its mAh, the more power it can provide the device before being depleted. Afterward, the power bank must be recharged before it can be of service again.

Review: Iniu BI-B63 USB-C PD (65W) 25000mAh/92.5Wh Power Bank

It’s been a while since I’ve reviewed a power bank, as I’ve been pretty happy with the units I have. However, I was approached by Iniu about reviewing their BI-B63 “ultimate” power bank under the review challenge terms and it seemed like a good step-up from what I already have.

This particular power bank sports a “flight-safe” 25000mAh/92.5Wh rating, while offering two USB-C PD ports and one USB-A port. Of note is that one of the USB-C ports is capable of 65W, making it suitable for powering many laptops that accept USB-C power input. This makes it a truly “universal” power-bank and one that is more than just to keep your phone or tablet topped up.

Unboxing

The unit was shipped directly from Iniu and seems to have taken some knocks while in transit. The unit comes in a white cardboard box with a glossy image of the power bank on the front and a very minimalist design on the rear. The product is from Shenzhen Topstar Industry Co. Ltd and is backed by a three-year warranty.

The brand claims to be “the 1st safe fast charge pro” and to “save your time, safe[sic] your charge”. I don’t usually care much for slogans, but this is the first time I’ve personally heard of the Iniu brand.

The product is packed in cardboard, which is better than being packed in plastic. The box encourages sustainability through recycling.

The cardboard tray seems to have suffered in shipment as the shifting weight of the power bank has crumpled the tray. However, it still seems everything arrived intact.

Included in the package is the power bank inside a milky plastic sleeve, a USB-A to USB-C and a USB-C to USB-C charging cable, a welcome guide and a drawstring bag. It is nice to see a full complement of accessories being provided.

The power bank itself has a nicely rounded design with a soft-touch matte-finish plastic contrasting with a mirror-gloss black plastic window. The front has a brand logo and feature text.

The rear of the unit has a full list of specifications and approvals. A ribbed indent is provided to allow the user to slide-out a phone holder. This is a small hook which protrudes out of the side of the power bank which allows a phone to rest against the power bank. This is a nice touch.

The hook protrudes out of the feature-less side of the power bank, while the other side hosts the power button which activates the display and resets the circuitry. A seam runs all the way around the power bank near the top face. Regardless, the unit is built solidly and the seam appears to resist being pried apart.

The three blue-coloured ports offered are clearly labelled. The leftmost is a 65W capable USB-C PD port, suitable for heavy loads such as a laptop. The middle port is a 30W capable USB-C PD port which is suitable for smaller laptops, tablets and phones. Finally, a USB-A port is provided to the right, supporting fast charge standards including QC3.0.

The supplied cables do not have any USB certification printing on their sheathing, although do have Iniu branding on the connectors. They support fast charging.

The power bank supports 45W input for faster charging from PD-capable sources. Outputs are capable of 65W, 30W and 22.5W individually, or up to 4530W for a total of 75W or 4522.5W for a total of 67.5W depending on the combination. As with more modern power banks, having multiple devices attached can produce limitations in support of quick charge – when all ports are active, the latter two ports are limited to 5V output.

User Experience

Overall, I found the unit to be solidly built and relatively resilient. The included drawstring bag is a nice touch, ensuring the unit doesn’t get scratched-up when placed into a bag. The matte soft-touch plastic finish is not my favourite, however, as it can attract greasy fingerprints and could become sticky in the long run.

The unit has an LED display which allows for the capacity to be shown as a percentage. This is convenient, as it allows the user to more accurately estimate the remaining charge. In my use, I found the capacity percentage to be slightly non-linear but still a relatively useful indication. Initially, however, I did experience the unit not charging past 94% or discharging and staying on at 0% for a lot longer than I expected. This suggests to me that perhaps cycling the power bank a few times is necessary for the system to “calibrate” its gauge. The display is, however, mounted at a slight angle.

Its behaviour is very similar to the LED display on the Blitzwolf BW-P12, blinking display when it falls below 10% remaining charge and blinking the units digit during charging. This suggests to me that the internal controller may be an Injoinic Technology chip or similar. Unfortunately, given how “tightly” constructed this unit is and the fact I don’t want to destroy it, there is no teardown in this review.

The display is also useful as it indicates the status of fast charging on the input and on the output. Of note is that the unit will show 100% charging status, but may still be charging as it is consuming current from the source. In this case, the fast charge icon may still be lit. I suspect this indication is there to have users think the power bank is fully charged when it is near the end of the slowest top-off part of the charge.

I had no problems running a Dell laptop from the power bank, which is excellent. Most of my electronics also charged just fine. The provision of two USB-C ports will delight those who have already moved towards a USB-C-only life, but may be a drawback for those with more legacy equipment. It may also be a drawback when charging equipment that does not comply correctly with USB-C standards, such as some flashlights which have incorrect resistors. This can lead to those devices not charging from USB-C to USB-C connections, but charging fine on USB-A to USB-C cables.

The outputs seemed to charge even moderately-low current devices just fine. After they are fully charged, the output may be turned off and attaching another load does not always wake up the power bank, necessitating pressing the power button.

Depending on the outputs or inputs connected, the capabilities will change resulting in a brief interruption to power. This is quite normal for these types of power bank, but it does mean that this is probably not a good candidate where UPS-style operation is a requirement.

Weighing the unit shows that it weighs slightly more than the 475g claimed in the specifications, measuring 488g. This is noticeable in your bag, but it is expected for the capacity.

Performance Testing

Further information was gleaned through testing the power bank using a BK Precision Model 8600 DC Electronic Load, YZX Studio USB-C Decoy Board, qc3control-based four-wire USB-A interface, Tektronix PA1000 Power Analyser, Rohde Schwarz NGM202 Power Supply and Rohde Schwarz RTM3004 Oscilloscope. Testing did take longer than expected due to the capacity of the power bank and some very ill-timed power outages that resulted in experiments needing to be repeated.

Discharge Voltage

This test looks at the output voltage during discharge to assess the stability of the output. Tests were performed at the rated maximum load for each output.

At 5V, the output was very stable and within the expected voltage range, noting the results for USB-C outputs are inclusive of voltage loss through cables and USB decoy board.

Output at 9V is also very stable over time and within expected ranges.

A similarly positive result is seen at 12V.

Finally, at 15V and 20V, the output is also very stable. This means that the charging speed for connected devices should be stable regardless of the state-of-charge of the power bank, and that the power bank has excellent output voltage regulation.

Discharge Capacity Efficiency

A summary of the computed discharge capacity and conversion efficiency figures are provided in the table below. Slight variations are expected due to differences in full-charge/empty determination of the power bank, temperature changes and quiescent consumption in the decoy board for USB-C ports.

Measured capacity ranges from about 79Wh to 87Wh of effective output when tested at the highest rated current for each output. Corresponding efficiency, assuming an honest 92.5Wh cell, ranges from 85 to 94%, with higher efficiency expected at lower currents. This result seems very reasonable.

QC3.0 Output Steps

Testing of the USB-A output in QC3.0 mode in continuous mode should result in 200mV steps on each increment or decrement voltage command.

Measured voltage steps were very close to 200mV, ranging from 193 to 207mV. Minimum voltage achieved was 3.6201V and maximum voltage is 12.0398V which is a good result.

Output I-V Curve

This test focuses on the change in output voltage as a function of load.

At 5V, it seems that USB-A shows a clear negative internal resistance behaviour which attempts to compensate for cable losses somewhat. The result for USB-C port 2 which is inclusive of cable losses seems to suggests that it may also have this behaviour, but the loses of the cable are greater than the compensation resulting in a slight loss of voltage with increasing current. The USB-C port 1, however, seems to have “steps” in the I-V curve where the voltage can abruptly change under load. This is not that normal to see, but may suggest different energy-saving operating modes. Regardless, all voltages are well within specification ranges. Over-current protection is active, cutting-out the output at between 3.37A to 3.42A.

At 9V, a similar trend is seen for USB-A and USB-C port 2, while USB-C port 1 does not have any voltage steps but also seems to exhibit a steeper voltage decline suggesting that it may not have a negative output resistance behaviour. The over-current protection is active and appears to have correctly adjusted for the USB-A port’s 9V 2A rating, cutting out at 2.33A.

At 12V, the same trend appears to persist. Over-current protection on USB-A now kicks in at 1.80A for a 1.50A rating, which is excellent to see.

At 15V and 20V, output is very much as expected and OCP disconnects the output at 3.40A.

Ripple Noise – USB-C (1)

Testing of ripple and noise was completed to assess the quality of the output power. In this case, the oscilloscope is used with 20MHz bandwidth limit switched on and AC-coupling on a 10:1 probe.

With the output at 5V and unloaded, the ripple measured 13.671mV peak-to-peak and there did not seem to be any power-saving mode active. Switching frequency appears around 300kHz. Loaded up to 3A, the ripple measured 16.611mV peak-to-peak, again, an excellent result.

At 9V/3A, the ripple measured 20.041mV peak-to-peak. At 12V/3A, this was 20.874mV peak-to-peak.

At 15V/3A, the ripple measured 16.905mV peak-to-peak. At 20V/3.25A, the ripple measured 18.914mV peak-to-peak. These results are excellent and are easily well-below the levels seen in branded mains chargers.

Zooming out, there is a bit of a random “walk” to the ripple at a longer timescale, which does increase the mean peak-to-peak voltage to 27.391mV. Even if we double the ripple figures previously measured, this is still an excellent result nonetheless.

Ripple Noise – USB-C (2)

The second USB-C port shows clear power-saving mode behaviour. The sawtooth waveform has a frequency about 2kHz and measures 29.4mV peak-to-peak. Loading up the rail at 5V/3A brings the ripple to 18.375mV peak-to-peak with a relatively sinusoidal waveform of about 125kHz.

At 9V/3A, the ripple measured 20.776mV peak-to-peak. At 12V/2.5A, the ripple measured 20.139mV. It is remarkable just how stable the ripple is throughout. The resulting values are again, excellent.

Ripple Noise – USB-A (3)

The USB-A output also shows power-saving mode behaviour, with an unloaded ripple measuring 34.3mV peak-to-peak. Loaded at 5V/3A, this reduces to 16.121mV peak-to-peak with a more triangular waveform.

Interestingly, attempting to maximise the ripple by changing the load, I was able to achieve 46.55mV peak-to-peak at a load of 100mA as it seems to be on the borderline of power-saving and active mode. Even this level of ripple is quite acceptable.

At 9V/2A, the ripple measured 18.081mV peak-to-peak. At 12V/1.5A, This was similar at 17.983mV peak-to-peak. Once again, the ripple measurement shows an excellent result that implies clean power for your devices.

Charge Time Efficiency

Testing of charging time was made using a bench-top power supply for 5V/3A (for highest accuracy) and two wall-chargers measuring the AC power – BlitzWolf BW-S6 QC3.0 Charger and Zendure SuperPort 4 100W USB-C PD Charger for the faster charge modes.

The charging times measured 8 hours 16 minutes and 4 seconds with 5V/3A input, 6 hours 26 minutes and 13 seconds for an 18W Quick Charge 3.0 input and 2 hours 29 minutes and 1 second for a 45W USB-C PD input. The advantage of USB-C PD charging is clearly evident and allows for this power bank to be charged relatively quickly. Charging at 45W only results in a little warmth being developed.

There are other power banks which may allow for 65W charging, but my experience is that they likely get quite a bit hotter and this could be detrimental to cell lifetime. As a result, the 45W charging rate is perhaps a good compromise in spite of the 65W output capability.

Conclusion

If you need a large power bank that can follow you on your travels and power everything including a laptop, the Iniu BI-B63 seems hard to fault. Solidly built, coming complete with a sleeve and cables, backed by a three-year warranty, this “ultimate” power bank has shown itself to deliver clean power with excellent ripple and noise results. It consistently enforces over-current protection for safety and has very stable voltage across the full discharge with voltages within the expected range. It even has an inbuilt phone stand!

Measured capacity ranges from about 79Wh to 87Wh of effective output with a corresponding efficiency ranging from 85 to 94% at full-rated current. Charging required 110.93Wh with a charge efficiency approximately 83.4%. These figures are all very reasonable.

Perhaps my only gripes are the soft-touch plastic finish which can attract greasy fingerprints and eventually get sticky. Another is the slightly-crooked capacity display which isn’t entirely accurate out-of-the-box and seems to need a few charges and discharges to read correctly. It also seems to indicate 100% even when charging has not fully completed.

In the end, it seems the Iniu BI-B63 is worthy of a recommendation based on these results, although longevity has not been tested. It is available through Amazon and Iniu Shop.
