BatPower ProE 2 ES10B 148Wh MS Surface Power Bank for Surface Book 3 2 1 External Battery Surface Laptop 4 3 2 1 Surface Pro X 8 7 6 5 4 3 Go Portable Charger and Surface 120W Slim Charger Adapter

I ordered this after reading the specs and reviews, since I have a Surface Pro 3 that is circa 2014 and my built-in Surface Pro 3 battery life had been reduced to less than one hour on a full charge. I love the Surface because I travel a fair amount and being able to work after boarding the plane, during takeoff, and during landing, are big deals to me. So the Surface is great since it isn't a laptop and is allowable for use at all times on board aircraft. But due to my lack of battery life, I was losing productivity on my flights and on short airport layovers if I couldn't find a convenient electrical outlet to charge my Surface.This monster of a backup battery comes with a nifty Surface Pro 3 charging cable that serves as a replacement for the standard charger, but hooks up to the BatPower ProE2 backup battery. I've used this thing on 4-hour flights and it still has half a charge left when I land. This includes me charging my phone as well while simultaneously charging my Surface Pro 3. I've carried backup batteries for years, but never one capable of charging a tablet as large as the Surface Pro 3. And while it is larger than any other battery that I've every carried, it's not overwhelmingly large and I don't mind its extra heft given it's awesome output and lasting power.So far, so good on the quality of this battery. It looks great, looks very well made, and seems to be working like a charm. I've only had it a couple of months, an unless something drastically bad happens, I won't be updating this review again. I'm pleased with my purchase and I checked this aspect beforehand since I travel a lot: You may need to check with individual airlines to ensure that this battery is okay with them to be transported on board due to it being over 100Wh. I checked with Southwest Airlines and they had no problem with it, and I travel Southwest most of the time. I will be checking with other airlines if / when I travel on them, as I would hate to have any issues at the airport with transporting a battery of this capacity. The TSA has no issues with this battery as long as your airline allows you to carry it on board. So just do your homework on various airlines that you travel and this battery should serve as a good option to extend your battery life on the Surface Pro 3.

My family has two Surface tablets and a slew of devices that need to be charged or run off of USB power. I bought this system (ProE 2 ES10) in 2020 and it gives me true portability for whatever I need to take on the road with me.Pros:- Charger is the best I have purchased and I love that there are two USB ports.- Battery outputs cover any need I have encountered. Last year I had a power outage that lasted about 12 hours which was during my work-from-home workday. My router/modem are on a hefty UPS, so with this system I was able to keep my computer and my phone working and even ran a USB powered light after it got dark!Cons:- Honestly, I can't state any. The only issue I have had was that I misplaced the cable that goes from the charger to the battery for the 90 W charge and I can't order that cable individually. However, I also have the BatPower Car Charger which also has that cable, so I have been able to keep going.Recommendation to BatPower: please carry your cables as individual orders. They are the components that are most likely to be lost while on the road.

I ordered a BatPower ProE 2 ES10B 148Wh Power Bank for my Surface Book. It works great and has a large capacity as promised. But it doesn't work with my another HP 17 laptop, which requires an input of 19V while the ES10B can only support up to 15V. I emailed BatPower ([email protected]) and asked if they have a Power Bank for both Surface and HP Laptop. The BatPower support quickly responded to my email and asked for the model number of my HP Laptop. They then recommended that I re-order EX10H for HP Laptop and promised to send me a cable for surface book for free. I am much impressed by their excellent service!

The good news to start -- this is a solid combo of a large WH battery and charger which allows you to (theoretically) use/charge your Microsoft Surface Pro or other device, along with multiple other devices, all simultaneously. The battery pack is heavy, as expected, but smaller than most direct competitors and worked well for roughly the first year.Now the bad news - after about a year the battery pack totally stopped holding a charge. I can now plug it in, leave it charging for a day, and upon disconnecting the charger the battery pack will not put out any juice at all. While this product is advertised as having a "30 day money-back guarantee and 18 month warranty", I was never able to get a response from the distributor or manufacturer to attempt to get it repaired or replaced under that 18 month warranty. I have been trying since January without any success.The charger does still work, so I at least have an extra Surface charger, but it most certainly isn't worth over $150+ for a battery which lasted about a year and under 200 charge cycles, and which claims a non-existent "warranty." All in all, I would strongly advise against buying products from this company.

I would completely give this unit a five star for functionality! It’s amazing. I bought the surface 4 pro 160 watt version and I love it. It charges my i7 512 16gb surface pro twice over as well as my iPhone and Nintendo Switch. It works very very well. It is large and heavy, but for that kind of power I couldn’t expect it to be much lighter. All the cable are very well built and of good quality. The only reason I gave it 4 stars is because of the lack of feedback the unit gives you. For nearly 200 dollars a small LCD screen with battery percentage wouldn’t be much to ask for and it could also display the 12 to 15 volt mode switch to. Also the input and output connections are identical and easily mistakenly plugged in wrong. Would of been nice to make them different but I get why they did it so you could use the power inverter to charge your laptop without the battery. All in all worth every penny. Hopefully in future a small screen with battery percentage and feedback info could be added.

I bought the 40000mAh battery pack and it is fantastic! It came with a variety of charging cables so I can charge my phone and tablet at the same time quickly. The pack lasts for quite a few charges too; about 8 charges for my phone and two and half for just the tablet. The power pack charges up very quickly too and doesn't take all night like some other power packs I researched before purchasing this one.This pack came with the required cables for my devices like the Surface Pro and USB-C. At one point my friends and I had an iPhone, a Galaxy phone, my Surface Pro, and my phone all charging from the power pack, while using the devices and it kept up with no problems. It didn't come with the charger for the iPhone though, but did come with cables for everything else.I'd recommend it to anyone looking for power on the go. Very pleased with this purchase!

I travel for work and use the ProE 2 to recharge my surface pro laptop while on long-haul trips or even in the back of taxis. Given it has the 3 USB ports and the 1 laptop charging output, I charge my watch, headphones, phone and laptop all at the same time!!Couldn't be happier with it and I bought it 2 years ago. Still working great.

Surface Pro 2017 をメインマシンとして使用しています。純正アクセサリーではないので、万が一本体に悪影響があっては非常に困りますが、５日程度かなりフルに使用しても問題はなかったです。家でバッテリー＆Surface本体に充電 → 外出時はACアダプタを持ち出さず、内蔵バッテリーまたはこちらのバッテリーを接続する使用方法で、丸一日12時間程度まで活動が可能になりました。電源のある場所に縛られずに活動できるのでストレスが減り、効率も上がりました。その分、出費と、持ち歩き重量は増えましたが、そのせいもあって、日帰りの時はACアダプタ持ち歩くのを止めました。（追記）注意点が一点ありました。BatPower の電源をオフの状態で Surface Pro と接続して、 BatPower の電源を入れると Surface Pro から電流が逆流します。Surface Pro のバッテリー残量が少ない時にこれを行ってしまい、 Surface Pro がバッテリー切れ状態になり、１分間程度使用できなくなってしまいました。今は気をつけるようにしていますが、最初は何が起こったのか分からず動揺しました。星１個マイナスです。

Ordered this after I saw a friend of mine using it. Have had it for 3 weeks now. Exactly as described on the website. Quick delivery. Product works exactly as described. Great selection of ports provides a very convenient charging station for my various devices. You need to pay attention to the instructions for outputting 15V vs. 12V when using the DC output for Microsoft Surface devices (newer devices and the Surface Book 2 require 15V DC). Highly recommended!

DC出力は15/12Vのため、ノートPCの充電はできないものがあります。手持ちのSurfaceはOKでしたが、入力が20VのノートPCはダメでした。USBポートにつなぐ機器はスマホやタブレットならば大丈夫ですが、ウェアラブル機器や充電式ペンだと無理でした。要求電力が小さすぎても充電できないようです。大容量なのが魅力的ですが、何でも充電できる物ではないことと、容量が大きすぎるために飛行機内持ち込み不可な点にはご注意ください。
