The 4-Bay T4s Intelligent Universal Charger from Tenergy is an automatic smart charger compatible with almost all types of rechargeable batteries, thereby eliminating the need to own multiple chargers. Capable of automatically identifying and charging Lithium Ion (Li-ion), LiFePO4, NiMH and NiCD rechargeable batteries, the T4s applies the appropriate charging mode, whether it be a constant charge current (CC), constant charge voltage (CV) or trickle charge.

Great product!
Bought this as a gift for a friend, and he loves it! It was a great replacement for what he had before, and was such great value! Built well, performs well, is compact, and is perfect for on-the-go use. Great replacement for carrying around multiple blocks for multiple devices. Might have to get one for myself...

All in one heavy duty charging brick
Love that this charger has a metal housing — it feels heavy-duty and well-built in a way most charging bricks don’t. Charges fast, handles a laptop, a phone, and a tablet at the same time without breaking a sweat, and the foldable prongs make it actually travel-friendly. 65W is the sweet spot for daily life: enough to power a MacBook Air or Pro, plus charge two more devices. Pros: • Solid metal build feels premium • 65W is plenty for laptops, tablets, and phones • Three ports (2 USB-C, 1 USB-A) • Foldable prongs for travel • Compact for the wattage Cons: • Heavier than plastic chargers (the trade-off for the build) • Maxing out all three ports splits the wattage, so not everything fast-charges simultaneously Tips: • Use a high-quality USB-C cable to actually hit fast charging speeds • For laptop charging, plug into the top USB-C port for max output • Great single-charger replacement for travel — covers laptop, phone, and tablet in one brick

100% would recommend, FAST and PORTABLE
The Anker 65W 3-Port Fast Compact Foldable USB-C Charger is a really nice charger overall. It has foldable prongs and 3 different ports, which makes it super useful for charging multiple devices at once, especially for college students or travel setups. It’s also really portable and easy to throw into a backpack but hefty in quality. The charging speed is excellent too. I can charge my MacBook from around 30% to 65% in about an hour. It does get a little warm while charging, but it cools down well and has never been an issue for me.

Compact, lots of power, great for travel.
I tested it at full power. It does what its advertised to do. At full power it does get fairly warm, not near warm enough to be a hazard. It can't be covered up, It may overheat if it's covered with stuff. I got it for travel. It will charge my computer, tablet and phone just fine. It shares the 65W, so charging of each device may slow as you plug in more devices
