Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ’em) products and single out the most convincing. While we’ve written before about our favorite battery packs and the most important things to have on you when you get stuck on the subway, we dove back in for a more comprehensive look. Below, the best power banks on Amazon. (Note that reviews have been edited for length and clarity.)

The best power bank with three USB ports

4.4 stars, 4,822 reviews

“Charged this power bank up and used it about 3 weeks later. Still seemed to be at full charge, little or no leakage over time. I recommend the smart-charge slot for the quicker charge rate. Charged my cell, my 8-inch tablet, and my cell again without emptying this charger. Still had 2 LED status lights of 4 showing on the battery. Recommend it.”

Best ultracompact power bank

4.7 stars, 6,791 reviews

“If you’re looking for peace of mind every time you leave the house, this power bank doesn’t disappoint. It’s the size of a credit card and only a hair heavier than my iPhone 6, making it extremely portable without being bulky and heavy. There’s a power button you press which shows how much power is left via 4 blue LEDs (when it’s dead, only one LED will flash). You can only charge one device with this power bank but I’m always impressed by how quickly this charges my iPhone 6 (from 10 percent to near full takes approximately 1 hour). So far, I’ve been able to charge my phone about 4 times from near empty to full before having to charge the power bank. It comes with a USB cable to charge the power bank itself as well as a drawstring pouch. What I love the most about this power bank is how effective it’s been. The power bank itself requires at least 2 hours to charge from empty to full but, once charged, your phone will charge to full in less time. As a result, I haven’t charged my phone using a wall outlet since I bought this power bank more than a week ago. Not having to worry about my phone going dead or being near a wall outlet is the best feeling next to purchasing a new phone.”

Best cylinder-shaped mini power bank

4.4 stars, 26, 187 reviews

“Absolutely LOVE this product. All other portable charger units I have found don’t even give a full charge to my phone like this one does. Very light and small to fit right in my purse. VERY pleased with this one.”

Best power bank with two USB ports

4.6 stars, 11,103 reviews

“Wow, this product is great. It is a life saver. It literally charges my iPhone 6s like 10 times. This product is amazing. I take it with me to work every day and since I don’t have a plug nearby this keeps me alive for the week with one charge. Sometimes my co-workers charge their phone and it still has juice left at the end of the week. I recommend this to everybody. This also charges your phone very very fast.”

Best under-$15 power bank with two USB ports and a flashlight

4.3 stars, 4,038 reviews

“I like the flashlight feature. It takes some time to charge but it’s worth it for such a decent size mAh battery pack. It tells you when it’s done charging your phone and it charges quickly. The clean smooth white casing looks sleek. It has 2 USB outputs. It has some weight to it. It was the perfect addition to my EDC bag, minus the fact it’s a tad bit heavy, but it’s not a hiking EDC, mostly car, and commutes-around-town bag.”

Best under-$35 battery pack with two USB ports and a flashlight

4.5 stars, 13,367 reviews

“Bought this to charge a cell phone and a small Asus tablet while hunting. Had plenty of juice to charge tablet once and phone twice. It arrived fully charged, so after I ran it down charging the aforementioned items, I let the portable charger recharge overnight. Seems durable — flashlight not very bright, but appreciate that it’s there.”

Best power bank for non-Apple laptops

4.4 stars, 387 reviews

“This is a very good product. It feels solid and is a real road warrior. I am using it for my laptop, which has some components in it that drain its internal battery fairly fast. I really have not had the laptop or the charger long enough to give a long-term analysis of the portable battery, but I am comfortable in feeling that this external battery is going to get a lot of use and will probably perform like a champ. I have almost drained the internal battery of my laptop a couple of times. I hooked up the portable battery and it charged the laptop battery all the way up as I continued to use the laptop hard core. I have no doubt that I can comfortably take my laptop on the road and have enough power for the whole day without having to worry about finding an outlet to plug in my laptop, or put the laptop in battery-saving mode. I have no doubt that this external battery is going to give a couple of charges to a mainstream laptop that is used mainly for productivity. You don’t even have to take the external battery out of your laptop bag, the cord that comes with it is quite long.”

Best power bank for laptops, including Apple

4.1 stars, 388 reviews

“This is an outstanding, versatile design that lets you charge any combination of devices and battery. For example, you can charge the battery + laptop + USB devices all simultaneously. Fantastic for business users, especially at, e.g., airport gates, where you can sit down anywhere convenient or in sight of of your boarding gate and still have full power for laptops and pads and phone. And of course onboard as well. Powers my MacPro 13” for 4+ hrs if the laptop is already fully charged and light on Wi-Fi usage, and of course recharges it if not. Recently I had the battery controller go bad on me, it just wouldn’t output power despite being fully charged. As it had an 18-month warranty, I emailed them the details of the symptoms, and without hesitation or delay, shipped a replacement the next day! FANTASTIC SUPPORT/SERVICE.”
